MF-27WXC Series
2.5Gbps SFP TRANSCEIVER MODULE
2.7Gbps Multi-Rate CWDM SFP Transceiver with Digital Diagnostic Monitoring Interface MF-27WXC Series
1. Description
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 a PD 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. Parameters Supply voltage Storage temperature Operating case temperature Relative humidity (non condensation) Symbol Vcc Tstg Tc Ratings 0 to +4.0 -40 to +85 0 to +70 5 to 85 Unit V °C °C %
