Four Lambda 10G / 1G Symmetrical Quadplexer

The LTF5302 is a combination of 10G EPON OLT and 1G EPON OLT optical transceivers in an SFP+ housing.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.
