The FTTH-OR20 series is a high-performance active home optical receiver specially designed for FTTH CATV and triple play networks. Adopting a high-quality aluminum alloy housing for superior heat dissipation, it ensures long-term stable operation even in high-temperature environments. It uses advanced full GaAs low-noise amplification technology and high-sensitivity photodetectors, delivering industry-leading receiving sensitivity down to -18dBm for digital signals.

This receiver features a customizable automatic gain control (AGC) circuit (default range -2~-12dBm, adjustable on request) to maintain stable RF output across varying input power levels. It supports optional built-in WDM for simultaneous transmission of CATV (1550nm) and PON signals (1310/1490nm, customizable 1270/1577nm for XGSPON), and an optional optical isolator to filter out non-1550nm wavelengths for dedicated CATV reception.

Equipped with multi-stage TVS transient suppression diodes for comprehensive surge and lightning protection, it also supports output port power feeding to supply downstream devices through RF cables. It provides flexible single-port or dual-port RF output options, with multiple optical connector (SC/APC, SC/PC, FC/APC, FC/PC) and RF interface (metric/imperial) options. It can work with ONU or EOC devices to realize triple play convergence of CATV, data and voice services.
