FTTH Optical Receiver Mini Receiver/CATV Optical Node

FTTH Optical Receiver with WDM
FTTH-SOR01A-WDM
Product ApplicationThis product is FTTH (Fiber to the Home) optical receiver, with low power optical receiving and optical control AGC technique, which can satisfy the demand of FTTH, and also can match with ONU or EOC for realizing the integration of three networks. With WDM, 1550nm CATV to be photoelectric converted for RF output, 1490/1310 nm PON signals directly pass, can transfer CATV+EPON by only one pc FTTH.
The product is compact, easy installation, and an ideal product for FTTH CATV network.
Performance CharacteristicAdvanced aluminum alloy house with good heat dissipation.RF full-GaAs amplifier circuit with low noise. Minimum reception at -18dBm digital signal, and minimum reception at -9dBm analog signals.AGC control range -2~ -12 dBm, while output keeps almost unchanged. (AGC range is customized).Low power consumption, high-efficiency switch power, can make sure the high reliability and stability of power supply. Power consumption is less than 4W. Also it adopts optical detecting circuit. Multi-stage anti-thunder devices (TVS transient suppression diode), strict anti-thunder system to ensure the safe operation of the equipment.With WDM built-in, it can realize the integration of three networks by one fiber. (1490/1310/1550nm)SC/APC or FC/APC optical connector, metric or British RF interface.It can realize the power supply of 12V DC input port feeding.Single or double output is optional.Remark: Two-stage amplification MMIC and Photodiode, both with brand name from G7/EU countries.Block Drawing
