OR21 FTTH High Level Optical Receiver
Product Description
OR21 FTTH optical receiver is specifically designed for CATV FTTH network. Its main feature is low power consumption, AGC optical constant level output, small Volume and high reliability. Adopting aluminum alloy shell, with optical control AGC circuit built in, compact structure and external modular power supply make the installation and debugging very convenient. It is an ideal product to build FTTH CATV network.
Product Feature
1. Adopts GaAs module as RF amplifying module, the optical receiving range for digital signal can reach -23dBm, and -15dBm for analog signal.
2. AGC control range 0~-10dBm, output level keeps unchanged.
3. Low consumption design and total consumption ≤2w, high reliable switching power supply with optical inspection circuit.
4. The output level can be adjustable within the range 0 -18dB, output level more than 88dBuV.
5. Realize the 6VDC~14VDC input port feeding way of power supply
6.The combined lightning protection measures of the optical receiver signal channel and power supply minimize the damage to the equipment due to lightning strikes;
7. The optical receiver has complete functions, and the parts adopt plug-in structure. The pins and sockets are copper and gold-plated, which can guarantee the performance and good contact;
8. The output form of the optical receiver can be branched or distributed, which is convenient for technical personnel to design, install and debug;
