Watertight optical transceiver and assembly method thereof

Abstract

The invention relates to a watertight optical transceiver and an assembly method thereof. The watertight optical transceiver comprises a watertight box body and a watertight cover plate fixed at the top of the watertight box body in a sealing manner. The watertight box body comprises a photoelectric conversion plate I fixing layer, a photoelectric conversion plate II fixing layer, a power supply module for supplying power to a photoelectric conversion plate I and a photoelectric conversion plate II, a switching module used for switching and distributing power supply signals in the watertight optical transceiver, and a wavelength division multiplexer fixing layer used for combining multiple paths of optical signals converted by a photoelectric conversion plate into one path of optical signals. Watertight panel connectors which are correspondingly connected with the layers respectively are fixed on the wall body on one side of the watertight box body in a sealing manner. The watertight optical transceiver can bear the water pressure of 0.5 MPa, can directly and normally work at the water depth of 50 meters underwater, does not need an additional watertight compartment, and is flexible and convenient to use, low in manufacturing cost and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of optical transceivers, and in particular relates to a watertight optical transceiver. Background technique [0002] Existing technology and disadvantages: With the popularization of the use of optical fibers, the application of optical transceivers is becoming more and more extensive. Various optical transceivers are also widely used in various fields such as aviation, aerospace, and ships. At present, some types of optical transceivers can achieve the level of anti-rain in order to adapt to the harsh natural environment, but they cannot achieve the function of deep water sealing. When underwater operations are required, they need to be placed in a special airtight cabin. Expensive, poor scalability, not convenient and flexible to use. Contents of the invention [0003] Based on the above problems, the present invention designs a watertight optical transceiver, which can work normally at a water depth o...
