1550nm 862MHz CATV Optical Receiver With CWDM
1550nm CATV receiver micro fiber optical node Active FTTH Optical Receiver
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.
