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. |
