Yogel 2 Outputs WDM 1310 1490nm CATV Optical Node
1550nm CATV receiver micro fiber optical node Active AGC Cable TV FTTH Optical Receiver Mini Optic Node
1. Product Description
This WDM optical receiver is specifically designed for CATV HFC network with FTTH structure. Its main feature is low power consumption,
AGC optical constant level output, small Volume and high reliability. Adopting aluminum alloy shell, with optical control AGC circuit built in, compact structure and external modular power supply make the installation and debugging very conveniently.
It is an ideal product to build FTTH CATV network.
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.
