Wavelength division multiplexing WDM receiver device and passive optical network system

Abstract

The invention provides a wavelength division multiplexing WDM receiver device and a passive optical network system, and relates to the technical field of communication equipment. The wavelength division multiplexing WDM receiver device comprises a receiver, a support is fixed at the bottom of the receiver, springs are arranged on the top surface in the support in an array manner, the springs are welded with the top surface in the support, and a push plate is fixed at one end of each spring, the push plate is located under the bottom of the receiver, a heat dissipation water cushion is arranged on the top face of the push plate, the two faces of the heat dissipation water cushion abut against the bottom face of the receiver and the top face of the push plate respectively, vent holes are formed in the surface of the receiver, a temperature sensor is fixed in the receiver, and a heat dissipation fan is arranged over the receiver, ventilation holes, the heat dissipation water cushion and the heat dissipation fan are adopted, so that the equipment is effectively cooled, the temperature of the equipment in use is prevented from being too high, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a wavelength division multiplexing WDM receiver device and a passive optical network system. Background technique [0002] WDM is to combine a series of optical signals carrying information but with different wavelengths into one bundle, and transmit them along a single optical fiber; The technology of transmitting in the same optical fiber of the line; at the receiving end, the optical signals of various wavelengths are separated by the demultiplexer (also known as the demultiplexer or demultiplexer, DemulTIplexer), and then the optical signals are separated by the optical receiver further processing to recover the original signal. In the same optical fiber, two or more optical wavelength signals are transmitted through different optical channels at the same time, which is called optical wavelength division multiplexing technology, or WDM for short. [0003] Ex...
