Twisted-pair and Direct-Attach Twinax Cables Will Become a Trend

Now fiber optic transceivers are commercially available for almost all international and industrial standards, including Ethernet, Fast Ethernet, Gigabit Ethernet, 10Gbit Ethernet. What’s take an important role in this situation is SFP fiber optic transceiver. So let’s take an eye on it. SFP is also called small form-factor pluggable which is a version of Mini GBIC. at first sight, you can find the size is only half of GBIC. It supports data rates up to 10 G. The SFP Transceiver are available with a variety of transmitter and receiver types. What’s more, it is with LC interface. The kind of SFP transceiver module called SFP-10G-SR in Fiberstore is a quite well choice, it is nearly same as Cisco SFP 10G SR. SFP is regarded as a hot pluggable module, this make it Effortless to alter and effortless for upkeep in comparison with conventional modules. It makes the Ethernet network easier to upgrade and sustain. End users can replace a Solitary SFP module Throughout the Procedure Rather of replace the complete board with various modules on it.

SFP+ twinax cables are copper cables with two SFP+ transceivers attached on either end. This  SFP cable is also known as Direct Attach Cables (DAC). Using twinax cable is significantly cheaper than connecting devices using two 10 Gbps fiber optic transceivers over fiber cable. There are two types of twinax cables. active and passive. In IBM b-type switches only active cables are supported which contain Vital Product Data (VPD) information. Twinax cable is available in length of 1m, 3m, and 5m. Also referred to as twinax, a direct-attach twinaxial cable is very similar to coaxial cable, except for one additional copper conductor core. Both twinax cores are protected by an insulator layer and another metallic conductor surrounding the core pair. Analogous to twisted-pair cables, both cores are twirled together to diminish interference effects from outside sources.

Originally created by IBM for shorter-distance connections, twinax cables offer a cost effective way to interconnect Ethernet devices within racks and across adjacent racks. These cables are usually accommodated into the transceiver housing of a switch or server. Direct-attach 10 Gigabit Ethernet twinax cables have Enhanced small form factor pluggable (SFP+) compatible connectors while 40 Gigabit Ethernet twinax cables deploy Enhanced Quad small form factor pluggable (QSFP+) connectors.

On both data rates, twinax cables are available in the following types. Active: Have components in the SFP+ or QSFP+ housing to improve the signal quality. Usually covers 7 and 10 meters. Passive: Have straight conduction between devices and are available in 1, 3, and 5 meters. for example Cisco SFP-H10GB-CU1M and what SFP-H10GB-CU1M in Fiberstore has same functions with Cisco’s and it also fully compatible with Cisco devices, the same time the price is lower than Cisco’s. Twinax cables have achieved high popularity in data centers because of their high benefit/cost ratio. As an additional advantages, twinax cables present a much lower bit error rate (1 error in 10 E18 bits transmitted) than the IEEE requirements for 10 Gigabit Ethernet connections (1 error in 10E12 bits transmitted). Although the 2004 IEEE 802.3ak standard was the first to introduce 10 Gigabit Ethernet in Twinax cables (10 GBase-CX4), this superseded solution was based on infiniband twinax cables, The twinax cables currently used in 10 Gigabit Ethernet are standardized by the small form format committee standard SFF-8431 and 8461.

Although the Ethernet standardization process has its fair share of politics, the study of its timeline remains a good way to access the networking industry trends over the last three decades. we can see some trends, such as twisted-pair roughly increased ten times its data rate every five years. That pace, however, did not continue in speeds higher than 10 Gbps. Optical fiber had a slightly faster development, being the first media to support data rates higher than 100 Mbps. It also presented the highest longevity among all media. Twinax cables have risen as a viable Ethernet option for 10-Gbps connections.

Because of the higher cost of optical transceivers, fiber is typically employed on links between switches, where higher speeds are required the earliest. High-volume connections, such as server access, depend on lower costs to justify an upgrade to faster data rates. For that reason, twisted-pair and direct-attach twinax cables have been the most popular choices for these connections.

Supply the SFP Transceiver Module and SFP Cables

Many people is likely t need SFP transceiver module or cables but they do not know which they should buy, and now I will introduce the two products in Fiberstore.

SFP-10G-SR is hot-swappable fiber transceiver module with 850nm VCSEL transmitter and PIN photo detector, it is fully compatible with IEEE 802.3ae 10Gbase-SR, electrical interface of the SFP+ SR is compliant to SFF-8431. SFP 10G SR features are low power consumption and it supports multi-rate from 2G fiber channel to 10G Ethernet. And we know Cisco SFP 10G SR is a SFP module that used for 10Gigabit applications, we Fiberstore supply Cisco the SFP 10G SR equivalent transceivers, they are compatible to work with both 50/125MMF and 62.5/125MMF, the characteristics of the other feature the good prices, excellent performance and 100% compatibility.

The SFP 10G SR hot swappable transceiver use LC connector interface, supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000 MHz*km MMF (OM3), up to 300m link lengths are possible. The SFP 10G SR modules are easy for deployment and maintenance, Rohs compliant and meet the IEEE standards for 10G Ethernet. 10 Gigabit Ethernet over copper is most commonly found in an SFP+ direct attach form-factor, in which twinaxial copper is terminated by SFP+ housing attached to the end of the cable, Some vendors refer to these as Direct Attach Copper (DAC) cables. These are used for fairly short runs, 1 to 7m for passive cables or up to 15m for active cables, with the latter drawing transmission power from the connected device. 10 Gigabit copper over UTP(10GBase-T) is also available, but is less common at the moment, as upgrading infrastructure to support it tends to cost more than using existing SFP+ ports.

In fact, External ports include 14 ports for 1 Gb or 10 Gb Ethernet SFP+ transceivers (support for 1000Base-SX, 1000Base-LX, 1000Base-T, 1000Base-SR, or 10GBase-LR) or SFP+ copper direct-attach cables (DAC). Ten ports are enable by default. An optional FoD license is required to activate the remaining four ports. SFP+ modules and DAC cables are not included and must be purchased separately. When 10 GbE started to be widely deployed in the data center, the most prominent copper cable type used was based on the enhanced small form-factor pluggable (SFP+) standard. The SFP+ reach is limited to about 7 m when using direct attached copper cables and around twice that when using active copper transceivers in the cable connectors. For longer reaches, optical cables are used between the racks. But these SFP+ cables are relatively expensive compared to Cat5.

The Cisco 10GBASE SFP+ modules offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications. Cisco SFP+ Copper Twinax direct-attach cables are suitable for very short distances and offer a cost-effective way to connect within racks and across adjacent racks. Cisco offers passive Twinax cables in lengths of 1, 1.5, 2, 2.5, 3 and 5 meters, and active Twinax cables in lengths of 7 and 10 meters. As we know Cisco SFP-H10GB-CU1M, this SFP-H10GB-CU1M can apply into 1-8G Fiber Channel and 1-10G Gigabit Ethernet, or these devices such as Hub, Switches, Routers, Servers, Network Interface Card (NICs), its function mainly include networking, storage, telecommunications.

Fiberstore is a leading manufacturer and supplier of fiber optic transceiver.module and SFP cable. They have a large quantity of SFP transceivers and cables in stock.

The Installation of SFP Module and Fiber Cable on SFP Optical Switching Module

First how to install the SFP Module? Optical fiber mode of GbE gigabit switching module contains a SFP with coil. SFP module is to convert electrical signals into light signal of laser products. Before install the SFP modules, we need to know that on the surface of SFP module there designs an integrated guide groove, the purpose is to prevent the user to put in the wrong direction when installation and location. when you insert the SFP modules, please use as little power as possible, because if you force the SFP modules propulsion SFP modules interface, it might damage the SFP modules or SFP modules interface. And SFP modules must be inserted into the SFP module interface to connect optical fiber cable properly, then another point we need to pay attention to is that you must pull out optical fiber cable from the SFP modules and then the SFP modules can be removed from the GbE exchange module.

Well, how to install the SFP modules? Here are some need to be aware of. If you install SFP modules under the condition of the electric, release the switch button must be dealt with half-open state, so that you touched the SFP modules linker 1.2 and 3. Warning: when installing laser products (such as a CD-ROM, DVD drive, fiber optic equipment, or the transceiver), pay attention to the following items: Don’t open the lid of the products. because open the lid is in danger of from laser radiation. Within the device there is not reusable service components. It is better to use control button or a program to adjust performance, don’t choose to use what you may be exposed to a laser. But there I would introduce SFP module to you, SFP-10G-SR in Fiberstore, this Cisco SFP 10G SR multi-mode transceiver is SFP+ module for duplex optical data communications such as 10GBASE-SR and 10GBASE-SW. This module is designed for multi-mode fiber and operates at a nominal wavelength of 850 nm.and it has a very high cost performance.

How to connect the fiber optic cable to SFP modules? When installed on the gigabit exchange module after the SFP modules can connect the fiber optic cable to the SFP modules. As for SFP cable, SFP-H10GB-CU1M is a quite well choice, the Cisco SFP-H10GB-CU1M in Fiberstore are suitable for very short distances and offer a highly cost-effective way to connect within racks and across adjacent racks. How to deal with the optical fiber cable? Note: in order not to damage the optical fiber cable, please follow the following guide to action.

1. Do not use optical fiber cable with folded arms furl.
2. When the spool of data to a trough, leave enough space (don’t let the cable into less than the radius of the 38 mm), make cable can h free scaling.
3. Straighten out the cabinet will cable don’t let it twisted together with other equipment
4. Do not place in tightly rolled up (radius of not less than 38 mm).
5. Don’t push too much pressure. You just need to confirm cable is supported.Installation of fiber optic cables
Complete the following steps to connect the fiber optic cable to the SFP modules:
1. remove optical fiber cable port of protective cap
2. install a good SFP optical fiber cable connected to the module
3. check the exchange module on the LED lights.When the normal work of the switching module, long green connection state of the light is bright.Pull out optical fiber cable
