RF Fiber Optic Module

Product Features
Power detection functions of transmit and receive light.
Can set radiation power by software.
Can set alarm levels of transmit light and receive light by software.
Adopting numerical control RF gain method, control gain adjustment by software.
Donor unit module has RF input power detection function (optional).
Donor unit module supply optical path automatic gain compensation function (5~10dB) (optional).
Supply FSK communication function. FSK adopting CC1000 chip, carrier frequency is 433MHz, dates rate can be set by user software. Can transparent transmission of monitor dates; at one time, dispose the date frame that accord with monitor Interface protocol, and achieve monitoring of optical module itself.
Can set FSK signal carrier power by software, setting range: 0~30dB.
Multi-split networking function, own Multi-split control.
Supply temperature detection, the range is:-40~100℃.
Supply FSK temperature compensation function. Can correct the frequency of FSK carrier automatically through module temperature change.
Save setting parameters, at one time, users can restore factory setting by software at any situations.
Description:
Optical Terminal Module can transfer the received RF signal into optical signal, then transmit via fiber mediums, and it can also transfer the optical signal back to RF signal at the same time. It is generally used by transmitter partner with receiver. In fact, the transmitter and receiver both have transmitting and receiving function, but their Optical wavelengths are different. By adopting peak multiplexing, we integrate two different optical wavelengths from transmitter and receiver into one module. Our Optical Terminal can be apply to fiber optic repeater products, and it can also use to simulated transmission of image and voice dates, and the simulated transmitting and receiving after date modulation.
Series:
