1 1 of 11 A he 10G Base LR-Lite SFP+ transceiver is intended for 10km reach service form 9.95Gb/s to 10.5Gb/s T 1310nm single mode high-speed communications equipment where low-cost, extraordinary performance and reliability are essential. It consumes low power, operates from a 3.3V DC power supply and is offered in the commercial and industrial temperature ranges. They are compliant with IEEE802.3ae 10GBASE-LR/LW, SFF-8431 and SFF The low jitter and low bit error rate optical assembly features a 1310nm DFB laser transmitter and PIN/TIA receiver. It incorporates the SFP+ MSA LVTTL Loss of Signal (Rx_LOS), Tx Fault (Tx_FAULT), MOD_ABS and Tx Disable (Tx_DIS) monitor and control functions and the SFF-8472 compliant digital diagnostic monitor feature. The differential AC coupled Tx and Rx data interfaces are CML compatible. The device is Class I laser safety compliant.
