Features

This is our latest high-end two-way output CATV network Fiber Optics Receiver. The L-RF-19R-RX is used to convert a fiber optic connection to RF (coax output). This module able to receive optical signals in either 1310nm or 1550nm. The second optical receiver adds further redundancy. QuestTel's CATV Fiber Optic receivers are designed high reliability with optical AGC (Optical Automatic Gate Control), high level RF output, ease of use, easy to read LED indicators, and suitable for high-level applications. The parameters will be displayed by singlechip to make the engineering debug more convenient.

How RF over Fiber Links Work

 

Converting  RF signals into light, then transporting the optical signal over fiber optic cable, is a complex process which requires a high degree of technical expertise. Incoming RF signals from the antenna or signal source are fed into QuestTel's RF over Fiber Transmitter Module via the 75 Ohm RF connector. The Module contains RF signal conditioning and provides complex impedance matching between 75 Ohm input impedance and the Laser, Laser  Control, APC, Monitoring and Alarm electronics. The Transmitter Module utilizes an Intensity Modulation scheme to convert RF signals into light. This modulated light is then transported through an optical fiber to the QuestTel's RF over Fiber Optical Receiver Module. The Receiver Module converts the modulated light back into an RF signal. The recovered RF signal is again complex impedance matched and amplified before it becomes available at the output of the Receiver Module.
