MF-2500FXE Series
2.5Gbps SFP TRANSCEIVER MODULE
2.7Gbps Multi-Rate, L-16.1, L-16.2 / LR-1, LR-2 SFP Transceiver
with Digital Diagnostic Monitoring Interface
MF-2500FXE Series
1. Description
www.DataSheet4U.com
This transceiver is compliant with Small
Form-factor Pluggable (SFP) MSA, and
optimized for SDH L-16.1, L-16.2 / SONET
LR-1, LR-2 applications.
The optical subassembly consists of two parts,
the transmitter with an uncooled DFB laser in
a hermetic sealed coaxial module, the receiver
with an APD preamp in a hermetic sealed
coaxial module and integrated circuits for
reshaping received optical signals.
The built-in serial ID recognition is
incorporated, which allows users to interface
with two wire serial interface that displays
information on manufacturer, part number,
link, distance, and other parameters.
The Digital Diagnostic Monitoring interface is
incorporated, which monitors transceiver
parameters including Temperature, Supply
voltage, Laser bias current, Laser power and Received optical power.
