Type: CATV Amplifier (GF-8055R)
Instruction of the product:CATV Amplifier (GF-8055R)
Features:
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
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
862MHz platform design, 550 MHz, 750 MHz, 862 MHz compatible, easy
online upgrade
Fittings for amplifier( attenuator, equalizer, two-way filter)
adopt plug-in type, adjustable and fixed attenuator and equalizer
RF level test port for input and output
Pre-distortion for equalizer, effectively eliminate bulge
phenomenon
