Description

The CZT-W431G-20D CSFP 1000BASE-BX LC 2-Channel bidirectional transceiver is intended for 20km reach service in 1250Mb/s single mode high-speed LAN and SAN data communications equipment where low-cost, extraordinary performance and reliability are essential. It meets the requirements of IEEE802.3ah 1000BASE-BX, consumes low power, operates from a 3.3V DC power supply and is offered in the commercial and industrial temperature ranges. The industry standard 2x10 compact small form pluggable (CSFP) package is fabricated with a rugged die cast metal housing and cage assembly. The low jitter and low bit error rate optical assembly features a 1490nm DFB laser transmitter and 1310nm PIN/TIA receiver. It incorporates the CSFP MSA LVTTL Loss of Signal (Rx_LOS), Tx Fault (Tx_FAULT) and Tx Disable (Tx_DIS) monitor and control functions and the SFF-8472 Rev9.5 compliant digital diagnostic monitor feature which is accessed via the I2C 2-wire serial ID interface. The device is Class I laser safety compliant.
