What I will talk about is that the widely used Cisco compatible SFP+ transceiver modules from one of the original Cisco transceiver manufacturers, Fiberstore. In the beginning let’s see what is the Cisco SFP+, or Cisco plus. SFP+ is the smallest size 10G transceiver compared with the former 10G transceivers X2 and XENPAK. Their advantage is that SFP+ transceiver modules are much more lighter weight and lower consumption. Cisco SFP+ transceivers are used for high speed 10Gigabit Ethernet, linking the equipment to fiber optic networks and offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications. And now I will mainly introduce four types of Cisco 10GBase SFP+ Transceivers SFP 10G SR, ER, LR(LRM), ZR from Fiberstore for your reference.

Cisco 10GBase SFP+Module: SFP-10G-SR

This Cisco SFP-10G-SR module is hot swappable fiber transceiver module designed for multi-mode fiber and operates at a nominal wavelength of 850nm. It works with 50 / 125 um MMF with max 300meters working spa. The SFP-10G-SR series multi-mode transceiver is SFP+ module for duplex optical data communications such as 10GBASE-SR and 10GBASE-SW. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C.
