Optical Transceivers SONET/SDH Transceivers for FTTx
2.5 Gb/s CWDM SFP Transceiver (Multirate) (PDF, 0.20 MB)
The JDSU CT2 Series 2.5 Gb/s Coarse Wavelength Division Multiplexing (CWDM) transceiver integrates optics and electronics in a Small Form Factor Pluggable (SFP) package. It is Multisource Agreement (MSA) compatible and designed for CWDM operation per ITU-T G.695 for unidirectional 8 channel black-link transmission (S-C8S1-1DX and S-C8L1-1DX). Although optimized for 2.5 Gb/s, the CT2 provides multi-rate capabilities and can be used for various protocols ranging from OC-3 (155 Mb/s) up to 2.7 Gb/s including 622 Mb/s, 1x/2x FC, GbE and 2x GbE.
The CT2 Series CWDM SFP transceiver provides a fully G.695 8 channel blacklink compliant interface between the optical Mux/Demux photonic layer and the electrical layer. Its microprocessor-based modular design implements all features specified in the SFP MSA compatible 2-wire Serial Digital Diagnostic Monitoring Interface for Optical Transceivers.
The major components in this module include an uncooled distributed feedback (DFB) based optical transmitter, a PIN or APD based optical receiver with integrated transimpedence amplifier (TIA), an APD high voltage circuit (if required), a microprocessor, a limiting post amplifier, and a laser driver. This CWDM transceiver design offers a "hot-pluggable" interface and is available in short haul (40 km, PIN) and long haul (80 km, APD) configurations.
