Abstract

The invention relates to the technical field of broadband multimedia access networks, in particular to a remote monitoring and controlling type optical receiver. The invention aims to solve the problems of large debugging and maintaining amount, troublesome debugging, low working efficiency and high network running cost in the prior art. The remote monitoring and controlling type optical receiver comprises a photoelectric conversion and low noise amplification unit, a radio frequency amplification and output unit, a data acquisition and remote numerical control attenuation unit, a microprocessor, an analog-to-digital conversion and communication interface unit, a machine working parameter LED display unit and a button adjusting unit. Compared with the prior art, the invention has remote control, reduces the working amount of site debugging and maintaining, improves the working efficiency and greatly reduces the network operation cost.

Description

Technical field: [0001] The invention relates to the technical field of broadband multimedia access network, in particular to a remote monitoring and control type optical receiver. Background technique: [0002] With the transformation of the HFC network from a simple cable TV broadcast network to a broadband multimedia access network, its business volume has increased sharply, and the number of optical receivers and the amount of debugging have also increased, and the link loss of each optical receiver is different. The difference in optical receiving power leads to uneven output RF levels of each optical receiver in the system, while traditional optical receivers require engineering debuggers to go to the site to rely on test instruments to debug, maintain and troubleshoot one by one, which also makes the optical receiver The debugging and maintenance work of the project has become particularly cumbersome. How can the engineering personnel not be on site so that the optica...
