SFP transceiver - SFP a brief introduction to the types and benefits

What is an SFP transceiver?

SFP stands for Small Form Factor Pluggable transceiver. This is a small form factor pluggable version.

SFP will be governed by multi-source agreements (MSA) of an important part of network providers, such as Agilent, IBM, Lucent, Siemens, Infineon, AMP / Tyco, and others.

The device has 10 I / O connectors on the back of the pack. This device interfaces with a motherboard network device (such as a switch, routers, media converters, and others) to afiber or copper cable network.

SFP transceivers for telecommunications and data communications. And their support SDH / SONET, Gigabit Ethernet, Fibre Channel, etc.

Benefits

Since the plug, which allows you to change the optical interface to the last step of the production of paper.

E 'can also accommodate different connector interfaces or a combination of SX and LX SFP.

The SFP cage is the surfacemounted on the PCB for the transceiver to accept. This not only offers easy replacement and reconfiguration, but also eliminates the extra steps for the production and reduce costs.

Since the optical component is removed from welding, SFP optical transceivers have a high reliability and enables the use of higher temperatures of welding.

Types of SFP

SFP transceivers are available in both single-mode fiber and multimode fiber. They are configured with 850 nmVCSEL laser at 550 m multimode fiber (SX), 1310 nm laser at 10 km / single mode fiber (LX), 1550 nm laser for more than 40 km (XD), 80 km (ZX), 120 km (or EZX EX) fiber single-mode optical transceivers and DWDM.

The industry has recently developed improved SFP MSA, known as SFP Plus (SFP +), which is designed for data transmission speed, lower costs and better thermal performance.

SFP + to support 8.5Gbit / s 10.52Gbit / s Fibre Channel, 10 Gbit / s Ethernet (10GBase SR, LR, and LRM), SONET OC-192(9.95Gbit / s) and G.709 "OTU-2" (10.7 Gbit / s).
