LTF7215 SFP+ 10G EPON ONU Transceiver

The LTF7215 is a 10Gb/s EPON 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 10.3125Gb/s and a 1310nm DFB burst mode uplink transmitter operating at 1.25Gb/s.  The LTF7215 is designed to be backward compatible with legacy Gigabit Ethernet PON systems. It is housed in a rugged die cast SFP+ package with the SC optical receptacle and is de-signed 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. The LTF7215 incorporates the monitor or control functions Tx_Burst and Rx_LOS.
