We have developed the 10Gb/s pluggable optical transceiver based on 10Gigabit Small Form Factor Pluggable Module (XFP) Multi Source Agreement (MSA) specification as a key device for optical interfaces between backbone fiberoptic networks and metropolitan area networks. It has 1,550nm EML-TOSA, APDROSA, and it is enabling 80km SMF transmission. The optical interface complies with Synchronous Digital Hierarchy (SDH) standard ITU-T G959.1 P1L1-2D2, the 10Gb/s electrical interface is based on XFI specification. Also, this transceiver has Digital Diagnostic Monitoring (DDM) Function by 2-wire interface. The transceiver is designed highly compact by the high density package technology, and the optimization of a heat radiation design realizes less than 4.5W of power consumption, so it is possible to operate at wide temperature range (Tc=0 to 70°C). It support the downsizing/low power consumption of a future optical transmission system. The feature is shown below. New Products Table 1.
