LTF7225 SFP+ XGSPON ONU Transceiver

The LTF7225 is a XGSPON 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 transmiter operating at 9.95328Gb/s.  The LTF7225 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 Directive 2002/95/EC for RoHS compliance.
