100Mbps-2.7Gbps, Multi-Rate DWDM
MF-27WXE Series
SFP TRANSCEIVER MODULE
2.7Gbps Multi-Rate DWDM SFP Transceiver with Digital Diagnostic
Monitoring Interface
MF-27WXE Series
1. Description
This transceiver is compliant with Small
Form-factor Pluggable (SFP) MSA, and
optimized for 100Mbps to 2.7Gbps Dense
Wavelength Division Multiplexing (DWDM)
applications.
The optical subassembly consists of two parts,
the transmitter with a cooled DFB laser in a
hermetic sealed module, and 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.

4. Absolute Maximum Ratings
Stress below listed absolute maximum rating may cause permanent damage to the module.
This is a stress only and functional operation of the module at these or any other conditions in excess of
those given in the operational sections of this data sheet.
Exposure to Absolute Maximum Rating for extended periods may affect module reliability.

5. Electrical characteristics
All parameters are specified over the operating case temperature.
Measurement conditions are at 2.666057Gbps +/-20ppm, NRZ PN2
23
-1 and 50%duty cycle data signal.
The DATA input/output signal interface is AC-coupled internally.
TX_DISABLE input signal level is LVTTL compatible. (With internally pull-up 4.7k to 10kΩ)
TX_FAULT and LOS (Loss Of Signal) output are Open-Collector/drain, and the levels indicated assuming 4.7k
to 10k ohm pull up resistor to Host_Vcc is present.
