LTF8505 SFP28 Optical Tranceiver
24.33Gb/s CPRI 850nm 100m

The LTF8505 SFP28 transceiver is intended for 100m reach service from 24.33Gb/s 850nm multi mode high ment where low-cost, extraordinary performance and reliability are essential. It consumes low power, operates from a 3.3V DC pow -speed communications equip- er supply .It is compliant with SFF-8431. 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. The device is Class I laser safety compliant.
