SFP28 25G EPON ONU Transceiver

The LTF7601 is intended for 25G EPON ONU DEMO in  separate SFP28 housing. It is a series module with an O-band 25.78Gbps upstream  transmitter and a O-band 25.78Gbps downstream receiver which work in TDM configuration. The transmitters can be controlled by the LVTTL Tx_Burst function and the receivers incorporate the LVTTL Rx_LOS output.  

The LTF7601 is designed to support up to 16 subscribers over distances of up to 20km in the ODN.  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.
