AGC, SNMP Bidirectional Optical CATV Receiver

Lightem L1C series ( two-port or four-port ), is a type of high-grade AGC, Network management, Bi-direction, outdoor optical receiver. Various operating parameters of machine are microprocessor-controlled, LED display. Through the keys of machine can adjust and set EQ、ATT. Optional network transponder, implement remote network management. Large dynamic range of optical AGC characteristics, Lightem L1C series ( two-port or four-port ) high output ,for FTTC, FTTN fiber access network. As a unit of CATV network RX, is a high performance, highly flexible, cost-effective CATV optical receiver.

L1C2CR series: AGC, Bi-direction, 2 ports output outdoor optical receiver, With network management Transponder.
L1C4CR series: AGC, Bi-direction, 4 ports output outdoor optical receiver, With network management Transponder.
