MF-27WXD Series
2.5Gbps SFP TRANSCEIVER MODULE
2.7Gbps Multi-Rate CWDM SFP Transceiver with Digital Diagnostic
Monitoring Interface MF-27WXD Series
1. Description
www.DataSheet4U.com
This transceiver is compliant with Small
Form-factor Pluggable (SFP) MSA, and
optimized for 155Mbps to 2.7Gbps Coarse
Wavelength Division Multiplexing (CWDM)
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.

7. Digital Diagnostic Monitoring Accuracy
The diagnostic monitoring features external calibration, and is calibrated over operating temperature and
voltage range. The monitor parameters are represented as defined in SFF-8472.
These parameters of the monitoring accuracy are guaranteed, as long as operating conditions of this SFP
transceiver do not exceed ranges defined below.
