LTH7226 XGS-PON OLT Transceiver Symmetrical 9.95328Gbps With Digital RSSI

The LTH7226 is intended for the XGS-PON OLT duplex optical transceiver module 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 EML operating at 9.953Gb/s and a 1270nm APD/TIA burst mode uplink receiver operating at 9.953Gbps and 2.488Gb/s. It is housed in a rugged die cast XFP package and is designed to operate over the industrial temperature range of –40 to 85°C.

The transceiver requires a 3.3V and 5V power supply for operation. The laser transmitter can be controlled by the LVTTL Tx_Disable function, and the optical receiver incorporates LVTTL Rx_SD output. 

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 Transceiver is ESD safe when tested according to IEC61000-4-2. The device complies with (US) FCC Class A, (Europe) CE Class A.
