The SFP-CWDM series single mode transceivers is small form
factor pluggable 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
