EPON 1.25G 1490nm TX/1.25G 1310nm RX PX20++ SFP Transceiver
EPON 1.25G 1490nm TX/1.25G 1310nm RX PX20++ SFP Transceiver

1.25Gb/s downstream / 1.25Gb/s upstream duplex data links that employ high-speed burst mode TDM receivers/transmitters. It is based on the IEEE802.3ah and CTC PX20++ specifications for bidirectional communications over a single fiber and incorporates a high performance 1310nm Burst Mode APD/TIA receiver and 1490nm CW mode DFB transmitter with internal optical isolator. The Transmit Disable (Tx_DIS), Transmit Fault (Tx_FAULT) and the SFF-8472 I2C diagnostic interface monitor and control functions are LVTTL compatible. The industry standard 2x10 small form pluggable (SFP) package incorporates the SC receptacle.Commercial temperature range is available. It is IEC 608251 Class I laser safety compliant and meets the EEC Directive 2002/95/EC for RoHS compliance.
