The SFP-CWDM series single mode transceivers is small form
factor pl able module for bi-directional serial optical data 
communications such as Gigabit Ethernet 1000BASE-ZX and Fiber 
Channel 1x SM-LC-L FC-PI. 
It is with the SFP 20-pin connector to allow hot plug capability. 
This module is designed for single mode fiber operating at a 
nominal wavelength of CWDM wavelength. There are eighteen 
center wavelengths available from 1270 nm to 1610 nm, with each step 
20 nm. A guaranteed minimum optical link budget of 24 dB is offered.
The transmitter section uses a multiple quantum well CWDM DFB 
laser and it is a class 1 laser compliant according to International
Safety Standard IEC-60825. 
The receiver section uses an integrated InGaAs detector preamplifier
(IDP) mounted in an optical header and a limiting post-amplifier IC.

Operating data rate up to 10G
