LTH5303 XFP 10G EPON OLT Transceiver

Three Lambda 10G DS/10G&1G US Tri-plexer

The LTH5303 is designed for low cost 10G EPON OLT solution. It is referred to the new standard IEEE 802.3av and configured with a

1577nm 10.3125Gbps EML laser, a 1260nm~1360nm 1.25Gbps~10.3125Gbps APD/TIA. The two upstreams are working at TDM mode, 

which can receive either the 1310nm 1.25Gbps EPON upstream or the 1270nm 10.3125Gbps 10G EPON upstream. The transmitters can be controlled by the LVTTL Tx_DISABLE function and the receivers incorporates the LVTTL Rx_LOS output. 

The LTH5303 is FDA 21CFR1040.10 and IEC 60825-2 Class I laser safety compliant and meets the EEC Directive 2002/95/EC for RoHS compliance.
