Do SFP MSA Benefits the Optical Transceiver?

When you purchase the 1000BASE-T SFPs for your switch, you may always see such description of them: This 1000BASE-T SFP transceiver is based on the SFP Multi Source Agreement (MSA). So, what's the SFP MSA? What's defined by the SFP MSA? Do SFP MSA benefits the optical Transceiver?

Multi-source Agreement(MSA)

A multi-source agreement (MSA) is an agreement between multiple manufacturers to make products which are compatible across vendors, acting as de facto standards, establishing a competitive market for interoperable products. Products created via multiple source agreements include SFPs and other network device interfaces.New MSA will define 1550nm silicon photonics based QSFP optical transceiver for 100G data center networks on single mode fiber (SMF) infrastructure.

SFP Multi-Source Agreement: This document establishesinternationally compatible sources of a pluggable fiber optic transceiver module in support of standards for fiber optic systems including Asynchronous Transfer Mode (ATM), FDDI, Fibre Channel, Fast Ethernet and Gigabit Ethernet, and Synchronous Optical Network (SONET) / Synchronous Digital Hierarchy (SDH) applications.

This MSA document strictly defines sufficient characteristics of a SFP transceiver so that system (e.g. Ethernet switch, Router, and media converter) vendors may Implement ports on their devices so MSA compliant pluggable optical transceivers SFP from any vendor will function properly. That is, transceivers could be purchased from any of the multiple sources in the open market, like Fiberstore. See Cisco GLC-T 1000BASE-T price on Fiberstore.

SFP transceivers also include a management (I2C) interface, an Electrically Erasable Programmable Read-Only Memory (EEPROM) and optional Digital Diagnostics Monitoring (DDM, Aka Digital Optical Monitoring or DOM). The EEPROM memory space is defined in the MSA and includes information describing the transceiver's capabilities, standard interfaces (e.g., SX, LX, EX, ZX), manufacturer and other data. This data makes available to the host system over the I2C interface, as is the status of the optional DDM functions.

What is defined by the SFP MSA?

The major elements or characteristics defined in the SFP MSAs are:

Mechanical Interface

• Transceiver edge connector to host PCB-mounted electrical connector mating
• Mechanical dimensions of the device (H: 8.5mm, W: 13.4mm, D: 56.5mm)
• Insertion, Extraction and Retention forces
• Host board mechanical layout (location/size of solder pads, etc.)
• Electrical connector mechanical aspects
• Bezel design considerations for host systems
• Cage assembly dimensions

Electrical Interface

• Timing requirements and Status I/O
• Pin definitions
• Module definition interface and data field description

Digital Diagnostics Monitoring (DDM) feature common in many modern SFP transceivers is defined by reference to the industry-standard SFF-8472.

Do SFP MSA benefits the optical Transceiver?

Optical transceiver form factors, defined through SFP multi-source agreements (MSAs), benefit equipment vendors by ensuring there are numerous suppliers to select from. No longer must a system vendor develop its own or be locked in with a supplier. Pluggables also decouple optics from the line card. A line card can address several applications simply by replacing the module. In contrast, with fixed optics the investment is tied to the line card. A system can also be upgraded by swapping the module with an enhanced specification version once it is available.

I propose that all such tries to undermine the value of these standards and subvert the free operation of the marketplace be vigorously resisted by consumers. Since there are many excellent choices, network operators should specifically avoid purchasing SFP modules directly from system vendors who attempt such coercive tactics. One reason should be to save money. System vendors primarily use these tactics to protect their grossly inflated prices. Second is to aid and encourage the creation and adherence to standards and, in addition, rebuke tries to undermine them. If you plan to buy the 3rd party or OEM transceivers (e.g. Cisco SFP compatible) for your switch, you had better to choose a vendor with high reputation. I recommend Fiberstore for you. Why? You may know the answer after you try.

More Cost-effective DACs from Fiberstore

Recently, Fiberstore cut the price of Direct Attach Cables (DACs) through strengthening the cost control. This change will make the DACs more cost-effective and better promote the high speed transmission.

Direct attach cables are used to connect one mobility access switch with another when forming a stack and now they are widely used in storage, data, and high-performance computing connectivity. With the development of communication technology and the increasing demands of people, 10 Gigabit, 40 Gigabit and even higher speed transmission gradually become more popular with people. DAC cables are one of the perfect choice for such high speed interconnect solutions.

Fiberstore supplies various kinds of high speed interconnect DAC cable assemblies including 10G SFP+ Cables, 40G QSFP+ Cables, and 120G CXP Cables. All of these direct attach cables can meet the ever growing need to cost-effectively deliver more bandwidth.

What's the Difference Between Transceiver & Transponder?

In a fiber optic communication network, there are many equipment and facilities to support the normal operation of the system. Fiber optic transponder and fiber optic transceiver are the one of these devices. Literally, both of them are with a prefix "trans". It seems to imply that there is a similarity between them. Actually, they are not the same. So, what's the difference between them, something difference on principle or applications? Today, we are going to have a discussion on this topic.

First, in order to better understand the difference between a fiber optic transceiver and a fiber optic transponder, we need to define what each one does.

Fiber Optic Transceiver Most systems use a "transceiver" which includes both transmission and receiver in a single module. Its purpose, in broad terms, is to transmit and receive data. In fiber optic communication, the commonly used transceiver modules are hot-swappable I/O (input/output) devices which plug into module sockets. The transceiver acts to connect the electrical circuitry of the module with the optical or copper network. Devices such as routers or network interface cards provide one or more transceiver module slot (e.g GBIC, SFP, XFP), into which you can insert a transceiver module which is appropriate for that connection. The optical fiber, or wire, plugs into a connector on the transceiver module. There are multiple types of transceiver module available for use with different types of wire, fiber, different wavelengths within a fiber, and for communication over different distances. The most commonly used fiber optic transceivers include GBIC, SFP, SFP+, XFP, CFP, QSFP etc. They are widely used for different application, eg. 10G, 40G fiber optic transmission.

Fiber Optic Transponder "Transponder" includes a transmitter and a responder. It is a similar device with transceiver. In optical fiber communications, a transponder is the element that sends and receives the optical signal from a fiber. A transponder is typically characterized by its data rate and the maximum distance the signal can travel. According to its specific applications, it is also known as wavelength-converting transponder, WDM transponder or fiber to fiber media converter. Fiber optic Transponders extend network distance by converting wavelengths (1310 to 1550), amplifying optical power and can support the “Three Rs” to Retime, Regenerate and Reshape the optical signal. In general, there is an O-E-O (optical-electrical-optical) function with this device. Fiber optic transponders and optical multiplexers are usually present in the terminal multiplexer as an important component for WDM (Wavelength Division Multiplexing) system. In addition, in nowadays market, many transponders are designed as protocol and rate-transparent fiber media converters that support SFP, SFP+ and XFP transceivers with data rates up to 11.32 Gpbs, and with seamless integration of different fiber types by converting multi-mode fiber to single-mode fiber, and dual fiber to single-fiber.

Fiber Optic Transceiver vs Fiber Optic Transponder A transponder and transceiver are both functionally similar devices that convert a full-duplex electrical signal in a full-duplex optical signal. The difference between the two is that fiber transceivers interface electrically with the host system using a serial interface, whereas transponders use a parallel interface. So transponders are easier to handle lower-rate parallel signals, but are bulkier and consume more power than transceivers. In addition, transceivers are limited to providing an electrical-optical function only (not differentiating between serial or parallel electrical interfaces), whereas transponders convert an optical signal at one wavelength to an optical signal at another wavelength. As such, transponders can be considered as two transceivers placed back-to-back.

Author's Note I hope you can start down the path to fully understanding transceivers, transponders, and the difference between them, particularly in a networking, Ethernet, or fiber-optic communications setting after reading this article. Of cause, knowledge is endless, if you still want to get more information about transceiver and transponder, I suggest that you should find more references to read. If you just need to buy the related products, I will recommend Fiberstore.com to you as usual.

Fiber Optic Transceivers Today and Tomorrow

Fiber optic transceivers is a self-contained component that can both transmit and receive. Usually, it is inserted in devices such as routers or network interface cards which provide one or more transceiver module slot, such as GBIC module, SFP transceiver, XFP, etc.

Fiber Optic Transceivers Today

Fiber optic transceivers for applications in the field of datacom are mostly characterized by a couple of established international standards. These standards define the electro-optical performance of a transceiver/transponder as well as its pinout and its physical outline and package, including the corresponding fiber optic connector interfaces.

Fiber optic transceivers meeting these standard are operating worldwide in numerous applications in mainframes, server clusters, storage area networks, wide area networks, and local area networks, and currently around 20 to 30 worldwide competing suppliers have been established. The number of partners involved in some important multisourcing agreements has seen an increase since 1989. This is also indicative of the increasing importance of industrial associations where both suppliers and applicators are represented. This speeds up the market penetration of novel components, systems, and applications. Nowadays, this does not seem to generate conflicts with the commonly agreed normative power of international standardization organizations such as the Internationnal Organization for Standardization (ISO), International Electrotechnical Commission (IEC), and International Telecommunication Union (ITU).

The demand for these transceivers has continuously increased during the past 10 years, and the prices have shown dramatic decreases of order of 25% per year. Consequently, the goal of all manufacturers is to offer a high level of performance, reliability, quality, and serviceability while maintaining cost-effective production in the face of drastically increased volumes to meet the market pricing.

Some Aspects of Tomorrow's Transceivers

The bit rates of fiber optic transceivers are continuously increasing in order to meet the worldwide demand for ever higher bandwidths. These bandwidth increases are called for by both existing storage and networking markets, as well as the parallel computing industry and high end server design.

In the past 10 years, a significant reduction of transceiver module size was possible due to significant progress in the downsizing of optical subassemblies and associated passive and active electronic comparison of the ESCON/SBCON outline, multistandard, small form factor (SFF), and parallel SNAP-12 transceivers. The function of the transceivers shown is described in detail in my previous blog posts.

Future transceiver design is likely to focus on power consumption, electromagnetic compatibility and immunity, and density. As data rates continue to increase, we will start to see transceivers used closer to the ICs on the board and not just at the card edge. It has also been demonstrated the is possible to incorporate optical components onto a chip, completely avoiding the deficiencies of high-speed signals on copper board traces. While these advancements may take their place in high-end computing systems, classical card edge transceivers are likely to continue to play their role into the foreseeable future to allow fiber cable connection for SANs and networking.

Where to Buy Fiber Optic Transceivers

Fiber optic transceiver is a very popular format that's recommended by a large number of fiber optic component providers. Fiberstore provide a full range of optical transceivers. Cisco, especially, you can find a full product line of our Cisco SFP modules, such as Cisco GLC-T 1000BASE-T, SFP-GE-T, GLC-FE-100LX, etc. Our SFP and SFP+ moduels are 100% compatible with a good price and enjoy same-day shipping.

What is the difference between GLC-T and SFP-GE-T?

What is the difference between SFP-GE-T and GLC-T? I have some information from Cisco Support Forums:

• GLC-T, 1000BASE-T SFP transceiver module for Category 5 copper wire, RJ-45 connector.
• SFP-GE-T, 1000BASE-T SFP transceiver module for Category 5 copper wire, extended operating temperature range, RJ-45 connector

GLC-T SFP copper SFP is a fiber optic transceiver module via Category 5 copper lines, Cisco GLC-T fiber transceivers provide 1Gbps data transfer and it provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over existing copper network infrastructure. GLC-T SFP is compliant to IEEE 802.3 and its dimension is 0.6 in x 2.8 in x 0.6 in. GLC-T is with plug in module type Mini-GBIC.

3rd-party GLC-T Key Features

• Support 1000BASE-T Operation in Host Systems
• For 100m reach over Cat 5 UTP Cable
• Hot-Pluggable SFP Footprint
• Support RX_LOS as Link indication function
• Fully metallic enclosure for low EMI
• Low power dissipation (1.05 W typical)
• Compact RJ-45 connector assembly
• Compliant with SFP MSA and IEEE Std 802.3-2002
• Detailed product information in EEPROM
• Commercial temperature range (COM): 0 to 70°C

Cisco SFP-GE-T fiber optic transceiver that works with 1000BASE-T. SFP-GE-T is with extended working temperature and it is with DOM support. SFP-GE-T is small form transceiver with RJ45 connector interface and it is with spring latch for high density applications.

3rd-party SFP-GE-T Key Features

• Support 1000BASE-T Operation in Host Systems
• For 100m reach over Cat 5 UTP Cable
• Hot-Pluggable SFP Footprint
• Support RX_LOS as Link indication function
• Fully metallic enclosure for low EMI
• Low power dissipation (1.05 W typical)
• Compact RJ-45 connector assembly
• Compliant with SFP MSA and IEEE Std 802.3-2002
• Detailed product information in EEPROM
• Commercial temperature range (COM):0 to 70°C

The third-party GLC-T and SFP-GE-T have the same Key Features. So no difference between them? I think that they are operationally identical and can be interchanged with no problems - the only difference is that the SFP-GE-T conforms to NEBS Level 3 and the GLC-T doesn't. And Then question is what is NEBS Level 3? I'll also add that the SFP-GE-T is a little bit more expensive...maybe $40 more (retail) but it works in switches or routers like the ASR while the GLC-T is for switches only.

What is NEBS and why is it important?

Long a requirement for equipment used in the Central Office in the North American Public Switched Network, the rigorous Network Equipment Building System (NEBS) criteria have become a universal measure of network product excellence. The NEBS compliance of GDC's products is a key advantage for access providers including Local Exchange Carriers (LECs), Competitive Access Providers (CAPs), Competitive Local Exchange Carriers (CLECs), Internet Service Providers (ISPs), and Access Service Providers (ASPs). Products that are NEBS certified are also expected to be top performers in enterprise net- work environments as well.

What does NEBS Level 3 Certified mean?

NEBS has three levels, Level 1, Level 2, and Level 3. Level 1 refers to cases where minimum compatibility with the environment is needed. Level 2 applies for limited operability of the product. 

Finally, NEBS Level 3 certification guarantees the maximum operability of the equipment. It also certifies that the equipment will perform well in harsh environmental conditions and will not interfere with other electronic devices around. NEBS Level 3 certified networking equipment is vital in mission-critical applications. More information about NEBS please Google it.

In a word, GLC-T with 1000BASE-T standard, SFP-GE-T with 1000BASE-T NEBS 3 ESD. But, for a 3rd-party SFP module, I still don't know what the difference between them.

To save more money, I suggest that compatible 3rd transceiver modules may be another good choice but you should ensure that your vendor is reliable. Fiberstore's fiber optic transceivers are 100% compatible with major brands, they are backed by a lifetime warranty so that you can buy with confidence. Additionally, customize optical transceivers to fit your specific requirements are available. If you have any requirement of transceivers, Fiberstore will be a good choice for you.
