1550nm CATV receiver micro fiber optical node Active AGC Cable TV FTTH Optical Receiver Mini Optic Node
1. Product Description
AGC Control range 1100 to 1600nm optical receiver WDM OR20 for Digital TV is home-based optical receiver catering to the ultimate goal of development of optical access and suitable for FTTH(fiber to the home) optical fiber network users access to the end. Analog or digital signal to home can be used together with the ONU or EOC achieving triple play.
2. Product feature
1. Low noise, high power, low power consumption and high cost performance
2. Excellent flatness in the bandwidth
3. Output attenuation control
4. With CWDM built-in, suitable for single fiber three wave system, RFTV working wavelength 1550nm and pass through wavelength 1310/1490nm. Can easily connect the ONU for EPON and GPON.

4.Application
1. Indoor Mini FTTH Optical Receiver/Optical Node is a household type receiver which meets to optical fiber to home for
digital or analog signal come true three network integration combined by ONU and EOC.
2. It adopts low optical power detector, GaAs and optical AGC control technique which meet the demands of CATV receiving.
A variety of functional products is slightly different in the application. it has AGC function and AGC cancustomize,
output level keeps unchanged which make the debugging very convenient.
3. FTTH optical terminal with convenient installation and debugging is an ideal product to build FTTH CATV network.
