4RRX series four-way reverse light receiving module
Characteristics
1. Each standard module contains four independent reverse return optical receiving channels, and is mixed into two RF outputs, which can form four independent receiving or two pairs of mutual backup receiving user site selection;
2. Optical link loss automatic compensation or output level manual control function is optional, the optical input power changes by 15dB, and the RF output level is unchanged;
3. The four-channel optical signal receiving power state is respectively displayed by three-color LED auxiliary display;
4. 30dB output level manual adjustment range;
5. Plug-in module design, small and exquisite appearance, flexible loading and unloading;
6. The air duct type design of the whole machine casing greatly improves the reliability of the whole machine. Technical Parameters:
