Ideal High-Speed Interconnect Solution

What is the Ideal High-Speed Interconnect Solution?

The ideal high-speed interconnect solution should have such features as optimized for short distances, low cost, low power consumption, small cable bend radius, low cable weight, high density, and low link latency. The only one solution which can meet all the requirements is the direct attach active optical cables.

Direct attach active optical cables, or active optical cables for short, are direct-attach fiber assemblies with fiber optic transceiver (SFP+, XFP, QSFP+, CXP etc.) connectors. They are suitable for short distances and offer a cost-effective way to connect within racks and across adjacent racks. Nowadays the Active Optical Cable (AOC) is accelerating data connectivity for storage, networking, and HPC applications. It leverages fiber optic technology for the transmission of data while reducing the weight, density and power consumption of traditional copper solutions. Note: Active optical cables have signal amplification and equalization built into the cable assembly, while passive optical cables don't. See

Advantages of Active Optical Cables

The AOC assemblies provide the lowest total cost solution for data centers by having the key advantages as following:

• Low weight for high port count architectures;
• Small bend radius for easy installations;
• Low power consumption enabling a greener environment.

Compared to Active & Passive Copper Cable Assemblies

1. Longer reach (> 7 meters)
2. Lower weight and tighter bend radius enable simpler cable management
3. Thinner cable allows better airflow for cooling
4. Lower power consumption
5. No need for power-hungry conditioning ICs on the host board
6. Can be used in architectures with challenging cable routing

Compared to Optical Transceivers

1. Datacenter/Consumer friendly: No cleanliness issues in optical connector
2. Cost-optimized: Not constrained by optical interface specifications driven by longer reach applications
(Note: However, the active optical cables cannot be routed through fiber patch panels.)

Ideal High-Speed Interconnect Solution

Today's enterprise data centers and networking environments are undergoing an infrastructure transformation, requiring higher speeds, greater scalability, and higher levels of performance and reliability to better meet the demands of business. As speed and performance demands increase, the AOC assemblies have become an integral part of the overall system design. However, AOC design margins and parameters vary widely, and can be the difference between an optimized, highly reliable fabric and the incompatibility issues that drive up support costs. There are various types of AOC assemblies for 10G, 40G, and 100G applications on the market. Judging from the cost performance, Fiberstore is the only one who can provide the most ideal high-speed interconnect solution of QSFP+ assemblies including 40G QSFP+ AOC, 40G QSFP+ breakout cable, and 40G QSFP+ to 8×LC AOC.

D-Link SFP Transceiver Datasheet

D-Link SFP Transceiver Overview

D-Link Gigabit Interface Converters are transceivers that connect Gigabit switches and 10/100Mbps switches with GBIC slots to Gigabit Ethernet networks, providing high-speed connections over the fiber optic or twisted pair cable. The fiber optic transceivers have standard duplex LC connectors for connection compatibility.

Overview

• DEM-310GT, 1000BASE-LX SFP 1310nm 10km, SMF
• DEM-311GT, 1000BASE-SX SFP 850nm 550m, MMF
• DEM-314GT, 1000BASE-LX SFP 1310nm 50km, SMF
• DEM-315GT, 1000BASE-LX SFP 1550nm 80km, SMF

Small Form Pluggable (SFP) Package

These transceivers use the industry-standard Small Form Pluggable (SFP) package. They slide into the mini GBIC slot of the Gigabit device. They provide the necessary signal amplification for data to be transmitted to the network cable from the port, and vice versa, for the port to receive data from the network cable.

Hot Swappable

All D-Link Mini GBIC transceivers are hot-swappable. You can remove or replace the GBIC transceiver with the system powered on. This permits modules and mini-GBICs to be added or swapped without interrupting the network.

Applications

Applications of the fiber transceivers include distributed multi-processing, Gigabit switch cascading, high-speed I/O file transfer, bus extension application, and channel extender/data storage.

What is DDM, DOM and RGD?

If it is your first purchase of fiber optic transceivers, you may be very confused with the fuction options "DDM", "DOM" or "RGD". So, what functons do they represent? And do you need these functions? Today, we will have a detailed explanation of them.

What's DDM?

DDM, namely Digital Diagnostics Monitoring, is a technology used in SFP transceivers in order to give the end user the ability to monitor real-time parameters of the SFPs. Such parameters include optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage etc.

What's DOM?

DOM, short for Digital optical monitoring, is familiar with the DDM function. It is also a feature which allows you to monitor many parameters of the transceiver module in real-time. DOM allows you to monitor the TX (transmit) and RX (receive) of the module, as well as input/output power, temperature, and voltage. Network administrators can then check and ensure that the module is functioning correctly.

Author Note: Obviously a SFP with DDM/DOM funstion is high-ender than one which without it. This is why most of modern optical SFP transceivers support DDM/DOM functions according to the industry-standard SFF-8472.

What's RGD?

You may be confused with the difference with the SFPs with "RGD" and the one without it, or you may be interested in the "-RGD" in the product number of some SFP transceiver modules. So, what does RGD stand for? RGD means rugged transceivers. In fact, these are enhanced transceiver modules which have been designed for greater durability, and can operate under more extreme conditions. Rugged transceivers may feature enhanced ESD protection, and extended operating temperature range so that it can help eliminate field failures without the need of costly external protection devices.

Author Note: In general, a rugged SFP can be identified by its product model, ie. -RGD. Specific situations depend on the specific vendors.

Other Functions in SFP transceivers

If you have an experience of buying Cisco SFPs, you may be confused with the part number with "=", because you can not find out the difference with the one without "=" according to the specification. In fact, "=" is also called a "FRU" part where FRU stands for "Field Replaceable Units". Those are the parts that can be used as "spare" or be shipped individually to replace damaged units. But the new parts that are ordered directly from a reseller or from Cisco usually don't come with the = sign. Thus, if you want to buy an SFP transceiver with the "FRU" part, you should ask your vendor to ensure this function.

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.

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.
