The CZGT-P4321-SC2DA transceiver is the high performance module for single fiber by using 1490nm continuous-mode transmitter and 1310nm burst-mode receiver. It is optical line terminal (OLT) for ITU-T G984.2. The optical transceiver is compliant with the Small Form- Factor Pluggable (SFP) Multi-Source Agreement (MSA). The CZGT-P4321-SC2DA is a low cost point to multi point (P2MP) Fiber to the Home, Business or Curb (FTTX) GPON OLT transceiver. It is designed for 2488Mb/s downstream / 1244Mb/s upstream duplex data links that employs high-speed burst mode TDM receivers/transmitters. It is based on the ITU-T G.984.2 Class C+ 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 Burst Signal Detect (BSD), the Burst Mode Receiver Reset (Rx_RESET), 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.It is fabricated with a rugged die cast metal housing and cage assembly. Commercial and industrial temperature ranges are available.It is IEC 60825-1 Class I laser safety compliant and meets the EEC Directive 2002/95/EC for RoHS compliance.
