LTF5308B SFP+ OLT Transceiver
XGS-PON/GPON Combo OLT Transceiver Symmetrical 9.953Gbps OLT
The LTF5308B is a combination of XGS-PON OLT and GPON OLT optical transceiver in an SFP+ housing. It is designed to support both the XGS-PON OLT and the GPON OLT specifications over a single fiber via coarse wave division multiplexing. The XGS-PON bidirectional link is configured with 1270nm/1577nm optics and the GPON link is configured with 1310nm/1490nm optics. The 1270nm and 1310nm optical burst mode receivers incorporate APD/TIA optics for maximum sensitivity. The 10G transmitter incorporates a 1577nm EML laser assembly and the 2.5G 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 LTF5308B is designed to support up to 32/64 subscribers over distances of up to 20km.
