LTF7221 SFP+ XGPON ONU Transceiver

The LTF7221 is a XGPON ONU duplex optical transceiver designed for low cost point-to-multipoint (P2MP) Fiber to the Home (FTTH), Business or Curb (FTTx) applications.

 It employs a 1577nm CW mode downlink ADP/TIA receiver operating at 9.95328Gb/s and a 1270nm DFB burst mode uplink transmit-ter operating at 2.48832Gb/s.  

The LTF7221 is designed to be backward compatible with legacy G PON systems.

 It is housed in a rugged die cast SFP+ package with a SC optical receptacle and is designed to operate over the commercial and industrial temperature ranges.

The transceiver requires a single 3.3V power supply.  

It is FDA 21CFR1040.10 and IEC 60825-2.Class I laser safety compliant and meets the EEC Direc-tive 2002/95/EC for RoHS compliance.
