WS-OTP2000L optical transmission platform module
WS-OTP2000L CATV optical transport platform is designed to meet front room equipment installation requirements of intensive development and design CATV fiber transmission admission, unified communications platform.
WS-RRX200M uplink optical receiving module
Ascending RRX200M uplink optical receiving module convert the uplink optical signal into RF output into the headend signal processing equipment, which constitute the uplink feedback channel. Modular uplink optical receiver is mainly used for uplink TV image signal, digital television signals, telephone voice signals and data (or data compression) received signal. This module contains four light detectors, used to receive four optical signal and converted into RF signal, then respectively for RF preamplifier, after can be modulated electron attenuator control gain output amplifier
WS-FDA200M series positive drive amplifier module amplify then output the input RF signal. The input RF signal pass through the electronic equalization circuit and control attenuation circuit firstly, then through the amplifier output level and slope adjustable. The slope and gain parameters through sampling, A/D conversion circuit, communication interface circuit and monitoring system of CPU data exchange in order to maintain, controlled and detailed display the working status. The front panel has -20dB RF detection port and it is convenient to detect the output signal.
