LTF5306 SFP+ OLT Transceiver

XG-PON/GPON Combo OLT Quadplexer

The LTF5306 is a combination of XG-PON OLT and GPON OLT optical transceiver in an SFP+ housing. It is designed to support both the new ITU-T G.987.2 XG-PON and the legacy ITU-T G.984.2 GPON specifications over a single fiber via coarse wave division multiplexing. The XG-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 LTF5306 is designed to support up to 32 subscribers over distances of up to 20km. 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 B, (Europe) CE Class B.
