LTE3680P-BC+4 SFP GPON OLT Transceiver

CLASS D 2488/1244 Mb/s With Digital RSSI Function

The LTE3680P 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 employ high-speed burst mode TDM receivers/transmitters. It is based on the ITU-T G.984.2 Class D 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. The Burst Signal Detect (BSD), the Burst Mode Receiver Reset (Rx_RESET), Transmit Disable (Tx_DIS), Transmit Fault (Tx_FAULT) and the interface monitor and control functions are LVTTL compatible. 

The industry standard 2x10 small form pluggable (SFP) package incorporates the SC/UPC receptacle. It is fabricated with a rugged die cast metal housing and cage assembly. Commercial range is available. It is IEC 60825-1 Class I laser safety compliant and meets the EEC Di rective 2002/95/EC for RoHS compliance.
