50G&10G&GEPON Combo OLT Transceiver

The LTQ5607-PC+ is a combination of 50GPON OLT, 10G EPON OLT and GEPON OLT optical transceiver in an QSFP-DD housing. The 50GPON bidirectional link is configured with 1342nm/1286nm optics, while the 10G EPON link is configured with 1577nm/1270nm ptics for symmetrical 10G EPON ONU and 1577nm/1310nm optics for asymmetrical 10G EPON ONU, and the GEPON link is configured with 1490nm/1310nm optics. The 1270nm,1286nm and 1310nm optical burst mode receivers incorporate PD/TIA optics for maximum sensitivity. The 50G transmitter incorporates a 1342nm EML+SOA laser assembly, the 10G transmitter incorporates a 1577nm EML+SOA laser assembly and the 1.25G transmitter incorporates a 1490nm DFB laser assembly. The transmitters can be controlled by the LVTTL Tx_DISABLE function and the receivers incorporates the LVTTL Rx_SD output. 

The LTQ5607-PC+ is designed to support up to 32 subscribers over distances of up to 20km, which is for the 50GPON&10G EPON&GEPON Combo access application.
