Optical Relay Station
Adopting exclusive PHILIPS optical receiving module for low noise and low distortion receiving, built-in six-section indication of input optical power.
Radio Frequency adopts Philips forward low noise module, with amplification output of the rear power multiplier module. The output mode can choose tap or distribution, and each interface has independent testing point.
Relay transmission adopts the original import DFB laser (ORTEL, AOL, XESTON). The rear bank power multiplier output signal provides RF drive level, so that insuring the Non-linear distortion Index of C/N. Meanwhile this device sets up the separate RF input threshold, which has the local input function and also can form the Outdoor Optical Transmitter by itself.
The laser operating temperature ATC and APC functions adopt micro-rocessor to control automatically. It can guarantee the best operating function; precise control optical output power and extend working life.
Micro-processor software monitors dynamically the crucial parameters of laser output power, bias current, cooling current and power etc. Still, it has LCD all states digital display, failure notice and alarming function as well.
The whole power and controlling line with multi-protection circuit, low-consumption and independent feed interface improves the stability and reliability of the device.
