LTF132X SFP28 Optical Transceiver

24.33Gb/s to 25.78Gb/s MWDM 10km

The LTF132x SFP28 footprint transceiver is intended for 10km reach service from 24.33Gb/s to 25.78Gb/s 12 wavelengths MWDM 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 extended temperature range. They are compliant with SFP28 MSA , SFF-8472 and SFF-8432. The low jitter and low bit error rate optical assembly features a MWDM DML laser transmitter. 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 inter-nal 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.
