Passive optical fiber expander with overload protection mechanism for communication

Abstract

The invention provides a passive optical fiber expander with an overload protection mechanism for communication, and belongs to the technical field of optical fibers. The expander comprises a connection member, and an outer coating mechanism is hinged to the side of the top of the connection member; an optical fiber information processing mechanism is arranged in the outer coating mechanism; a load processing mechanism is arranged in the middle of the optical fiber information processing mechanism; a broadband switch is arranged at one end of the load processing mechanism; the connection member comprises a square connecting panel; supporting connecting rods are fixedly mounted on the two side edges of the surface of the connecting panel; and an optical branching device is fixedly mounted on the side of the surface of the connecting panel. According to the invention, rapid leading-out and linking of the passive optical fiber are ensured; a user firstly carries out hot melting treatmenton a plurality of optical fibers with the same model, utilizes a fused biconical taper method to make two (or more) optical fibers with coating layers removed lean against each other by adopting a certain method, melts the optical fibers under high-temperature heating, and stretches the optical fibers towards two sides at the same time, and finally forms a special waveguide structure in a biconical form in a heating area.

Description

technical field [0001] The invention belongs to the field of optical fiber technology, and in particular relates to a passive optical fiber extender with an overload protection mechanism for communication. Background technique [0002] Optical fiber, short for optical fiber, is a fiber made of glass or plastic that acts as a means of light transmission. [0003] The transmission principle is "total reflection of light". [0004] 1) Existing passive optical fibers are likely to cause serious load pressure during use, and the more the number of optical fibers connected, the greater the load pressure will be, and the greater the impact on broadband transmission of optical fibers will be, resulting in broadband speed At the same time, the temperature rises higher and causes more serious thermal damage to the optical fiber, which is prone to fire. The passive optical fiber expansion protection mechanism cannot cut off in time according to the temperature of the optical fiber, ca...

Problems solved by technology

[0006] The purpose of the present invention is to provide a passive optical fiber extender with an overload protection mechanism for communication, which aims to solve the problem that the existing passive optical fiber in the prior art is likely to cause relatively serious load pressure during use, and the connection The more the number of optical fibers imported, the greater the load pressure will be, and the greater the impact on the broadband transmission of the optical fiber will be, resulting in a decrease in the broadband rate. At the same time, the temperature rises higher, resulting in more serious thermal melt damage of the optical fiber, which is prone to fire. The passive optical fiber extension protection mechanism cannot cut off in time according to the temperature of the optical fiber, causing more serious problems
