L-Band Satellite Optical Transceiver

Introduction

The CLB satellite L-band signal optical transceiver is composed of an optical transmitter and an optical receiver. It mainly converts all the L-Band analog or digital satellite signals (SAT-IF) received by the satellite receiving antenna high-frequency head LNB into optical signals. Transparent, high-quality, long-distance transmission. Mainly used for aerospace satellite, military satellite, direct broadcast satellite L-Band fiber uplink/downlink.

Features

Used to receive and transmit C-band, KU-band satellite signals

Using a 19-inch 1U standard rack, the front color LCD provides display of optical power, temperature, operating voltage, input or output RF level, etc.

The optical transmitter can supply power to the LNB through the RF port or not. If the output voltage of the power supply is +13V or +18V, the maximum output current is 450mA; the user can choose the setting through the color LCD screen.

The LCD of the optical transmitter can display the light emission power, LD operating current, the operating temperature of the optical transmitter, the voltage output to the LNB, and the level of the input RF signal.

The optical receiver can supply power to the machine through the RF interface, the input voltage is +13V or +18V, the maximum output current is 300mA, and it can also be powered by the AC220V dual power supply of the machine
