Description
Product description
HY-21-R24 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
- Brushed aluminum shell with good heat dispersion.
- Adopts GaAs module as RF amplifying module, the optical receiving range for digital signal can reach -15dBm, and -9dBm for analog signal.
- AGC control range 0~-9dBm, output level keeps unchanged.
- Low consumption design and total consumption ≤4w, high reliable switching power supply with optical inspection circuit.
- SC/APC or FC/APC optical connector
- The output level can be adjustable within the range 0 -18dB, output level more then 80dBuV.
- Realize the 8 v input port feeding way of power supply
