LTF5302 SFP+ 10G EPON OLT Transceiver

Four Lambda 10G / 1G PR30 Symmetrical Quadplexer

The LTF5302 is a combination of 10G EPON OLT and GEPON OLT optical transceivers in an SFP+ housing. It is designed to support both the new IEEE802.3av PR-30 10G and the legacy IEEE802.3ah PX-20 PON specifications over a single fiber via coarse wave division multi plexing. The 10G bidirectional link is configured with 1270nm/1577nm optics and the 1G 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 DFB laser assembly and the 1G 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_LOS output. 

The LTF5302 is designed to support up to 32 subscribers over distances of up to 20km.
