We are manufactures company in exporting CATV and CCTV products, including CATV Amplifier, CATV Modulator, Optical transmitter, Optical node, EDFA, CCTV Transmitter&receiver, Media converter, Fiber-Optic patch cord, Optical coupler and so on.
Features:
1. Imported amplifying module to amplifying RF signal and send it into distribution network. Silicon and GaAs amplifying module effectively enhance non-linearity parameter, output capability and decrease noise figure.
2. Two-way modularizing designing, including forward channel, return channel, Send back upstream RF or data signal can be sent to optical node. User configurable, defaulted forward channel.
3.862MHz platform design, 550 MHz, 750 MHz, 862 MHz compatible, easy online upgrade.
4. Fittings for amplifier(attenuator, equalizer, two-way filter) adopt plug-in type, adjustable and fixed attenuator and equalizer.
5. Pre-distortion for equalizer, effectively eliminate bulge phenomenon.
