The FT-BE-F8505 SFP+ transceiver is intended for eSR reach service from 25.78Gb/s 850nm multi 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 temperature range. It is compliant with SFF-8431 and SFF-8432. The low jitter and low bit error rate optical assembly features a 850nm VCSEL 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. The differential AC coupled Tx and Rx data interfaces are CML compatible.
