The SYSP 1310nm DFB 10Gigabit Transceiver is designed to transmit and receive serial optical data over single mode optical fiber with 10Km.They are compliant with SFF-8431,SFF-8432, 10GFC Rev 4.0, FC-PI-4 Rev 7.0 and IEEE802.3ae 10GBASE-LR/LW.The transmitter converts serial CML electrical data into serial optical data compliant with the IEEE 802.3ae standard. An open collector compatible Transmit Disable (Tx_Dis) is provided. When TX_DIS is asserted High, Transmitter is turned off. The receiver converts serial optical data into serial CML electrical data. An open collector compatible Loss of Signal is provided. The RX_LOS signal indicates insufficient optical power for reliable signal reception at the receiver. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472 .
