Single-Mode SFP+ Module, Supports full-duplex. Cable Length: 10km using 9/125um Single-Mode Fiber. Always keep the protective dust plug on the SFP's optical bores until you are ready to make a connection. The wide variety of modules gives you flexible and cost-effective options for all types of interfaces. Cisco offers a range of GBIC, SFP, XFP, SFP+, CXP, CFP, Cisco CPAK, and QSFP+. The SFP+ transceivers are high performance, cost effective modules supporting data rate of 10Gbps and 40km transmission distance with SMF. The transceiver consists of three sections: a Cooled EML laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU. An SFP (Small Form-factor Pluggable) is a compact, hot-pluggable transceiver module that allows networking equipment — including switches, routers, servers, and media converters — to support different physical media, such as optical fiber or copper, without replacing the host hardware. Think of it as the “translator” for your network equipment, converting electrical signals into optical signals. Smartoptics SFP modules are for running various optical data communications such as 1/2G FC, Fast Ethernet and Gigabit Ethernet.
