Overview

SK-OR-860A indoor optical receiver is a kind of high performance optical receiver. It is mainly used in HFC transmission network opt-electric conversion node and backbone. This kind of optical receiver adopts low noise, wide dynamic range photo detector, equip-in broadband low-noise GaAs MMIC amplifying circuit combined with GaAs power doubled module reasonably, to make optical receiver with perfect noise index and perfect CSO, CTB index; featured with optical control AGC and network management function, it improves network link reliability; It is also featured with output attenuation and equalization remotely control function. Output level adjustment is very easy.

Features

● 1310nm and 1550nm dual-window receiving;

● Front panel LCD displays equipment each operation parameters real timely (optical power, attenuation, equalization, output level and voltage);

● Front panel pressing button adjusts RF output level and slope;

● Optical control AGC function, to make output level keep stable when input optical power is in the range of -6~+2dBm;

● High reliability double push-pull type switching power supply, small temperature rising, high conversion efficiency, wide voltage adaptive range;

● Equipped-in network management responder (sort II) complying to SNMP protocol, RJ45 telecommunication interface, the subscriber could manage equipment through network management system, to improve network operating reliability;

● High quality full aluminum alloy housing can unique heat dissipation structure design, excellent heat dissipation, to ensure equipment operation long term and stably.
