LTF122X SFP28 Optical Transceiver

25.78125Gb/s LWDM 10km

The LTF122X SFP+ footprint transceiver is intended for LWDM 10km reach service 25.78125Gb/s high-speed communications equip-ment where low-cost, extraordinary performance and reliability are essential. It consumes low power, operates base on 3.3V DC power supply. They are compliant with SFP28 MSA , SFF-8431 and SFF-8432. The low jitter and low bit error rate optical assembly features DML 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. It utilizes internal clock and data recovery (CDR) units on transmitter and the receiver chains for low jitter compliance. The differential AC coupled Tx and Rx data interfaces are CML compatible. It is FDA 21CFR1040.10 and IEC/EN 60825-1:2014, IEC/EN 60825-2:2010 Class I laser safety compliant .
