Description
This series single mode transceiver is SFP+ module for duplex optical data communications. This module is designed for single mode fiber and operates at a nominal DWDM wavelength from 1528nm to 1566nm as specified by the ITU-T.It is designed to deploy in the DWDM networking equipment in metropolitan access and core networks.It is with the SFP+ 20 -pin connector to allow hot plug capability.
The transmitter section uses a DWDM EML laser and is a class 1 laser com pliant according to International Safety Standard IE C-60825.
The receiver section uses a PIN detector and a limiting post-amplifier IC. This series are designed to be compliant with SFP+ Multi-Source Agreement(MSA) Specification SFF-8431
