- Introduction
- Parameters
·Adopt international famous brand high sensitive PIN
optical detector or integrated optical receiver module and RF amplified module.
·Low optical power receiving range:
-9~+3dBm.
·Built-in plug-in(reserved) return optical
transmission group.
·Bandwidth could upgrade in the range of
862MHz-1000MHz with module changed.
·Digital display and electric control of attenuation
and equilibrium without insert extra attenuator.
·High isolated duplex filter with 4 ways
distributed output.
·Controlled by optical AGC, when input
optical power is -9-+2dBm, output power level and CTB, CSO remain unchanged.
·External RF power level output test port, convenient
for engineers to maintain.
·High reliable power switch and strict
lightning-proof system.
·Aluminum cast waterproof case, high quality
aluminum alloy drawbench panel.
·Reserved data communication interface, can
connect with class Ⅱ network management responder, convenient for
distant monitor and maintain.
