This article is talking about the widely used Cisco compatible SFP plus transceiver modules from one of the original Cisco transceiver manufacturers, Ingellen Co., At the beginning let's see what is the Cisco SFP+, or Cisco plus. SFP+ is by far the smallest size 10G transceiver compared with the former 10G transceivers X2 and XENPAK. It is 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.
This article will mainly introduce four types of Cisco 10GBases SFP+ Transceivers SFP 10G SR, LR(LRM), ER, ZR from Ingellen for your reference.

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.
