Bi-directional Optical Receiver(Outdoor type)ERB802C  

Products Description

ERB802C Outdoor Bi-directional Optical Receiver is a 750MHz economical receiver with the outdoor waterproof structure. It’s specially designed for HFC network. It has many advantages such as low noise, high sensitivity and well reliability. It is in according with the requirements of the network perfection and the subscribers in the extensive countryside and the outlying districts. We adopt the advanced design to premise the index and reduce the cost greatly. There is RF calibrating circuit, in order to increase the in band flatness, the subscriber can adjust it conveniently by the equalizer. It also has the alarm pilot lamp. When the input optical power is below -8dBm, the red lamp will shine, if you want to know the input optical power correctly, and there is no optical power meter, you can measure the voltage in the examining points by avometer, and the corresponding optical power can be read from the diagram.
