Because the 1300nm wavelength takes advantage of the lower dispersion and attenuation region of glass optical fiber, this transceiver is capable of link distances of 2km at the maximum data rate. Description Receiver The OPF5112 from Optek is a high performance, cost effective module for serial optical data communications applications specified for 100 Mb/s operation. This transceiver operates with +3.3V power supply and is housed in a plastic package with an industry standard 1 x 9 form factor. The OPF5112 is a duplex ST transceiver designed for use in Fast Ethernet 100 Base-FX interface. The characterization is performed in accordance FDDI PMD Standard. Likewise, the Fast Ethernet Alliance defines the Physical Layer for 100 Base-FX for Fast Ethernet to be the FDDI PMD Standard. The receiver optical sub-assembly consists of a InGaAs PIN photodiode and transimpedance amplifier in an integrated package to optimize performance. The resulting analog output is coupled to a post-amplifier for signal conditioning and conversion to differential, PECL high-speed outputs. OPF5112 consists of a transmitter optical subassembly, a receiver optical subassembly and an electrical sub-assembly. All are housed in a plastic package and the combination produces a component of high performance and reliability.
