LTF2328 SFP28 Optical Transceiver

25Gb/s 40km

The LTF2328 SFP+ footprint transceiver is intended for 40km reach service from 24.33Gb/s to 25.78Gb/s Tx1270nm/Rx1310 single 

mode high-speed communications equipment where low-cost, extraordinary performance and reliability are essential. It consumes low 

power, operates base on 3.3V DC power supply and is offered in the Industrial temperature range. They are compliant with SFP28 MSA , SFF

-8431 and SFF-8432. The low jitter and low bit error rate optical assembly features a 1270nm DML laser transmitter and APD/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.
