MPO/MTP cluster prefabricated optical cable component

Abstract

The invention discloses an MPO / MTP cluster prefabricated optical cable component which comprises an adapter component, a first plug body component and a second plug body component. Two ends of the adapter component are open and through to form an inner cavity, a guide part is disposed in the middle of the inner cavity, and sealing bodies are respectively disposed on two sides of the guide part. The first plug body component is disposed outside a first optical fiber connector. One end, located at the head of the first optical fiber connector, of the first plug body component is provided with an opening to allow the head end face of the first optical fiber connector to be exposed. The second plug body component is disposed outside a second optical fiber connector. One end, located at the head of the second optical fiber connector, of the second plug body connector is provided with an opening to allow the head end face of the second optical fiber connector. The opening end face of the first plug body component and the opening end face of the second plug body component are respectively correspondingly connected with the sealing bodies in the adapter component. The head of the first optical fiber connector and the head of the second optical fiber connector are aligned and coupled in the guide part of the adapter part to achieve dust prevention and water prevention.

Description

technical field [0001] The invention relates to the technical field of optical transmission, in particular to an MPO / MTP bundled prefabricated optical cable assembly. Background technique [0002] MPO is the name of Japan's NTT company for bundled fiber optic connectors, and MTP is the name of USCONEC for bundled fiber optic connectors. The working principles of MPO and MTP are exactly the same and are compatible with each other. There are two differences: one is that the spring inside the MPO plug is a circular structure, and the spring inside the MTP plug is an oval structure; the other is the orientation of the MPO male plug. The pin tops are conical and the MTP male guide pin tops are football shaped. [0003] The working principle of the MPO / MTP bundled optical fiber connector is: the T-shaped adapter body of the MPO / MTP male plug is aligned with the T-shaped adapter groove on either end of the MPO / MTP adapter, and then the plug is inserted firmly, and a "pop" sound is...

AI Technical Summary

Problems solved by technology

[0004] The MPO / MTP bundled prefabricated optical cable assemblies in the prior art are either limited to optical signal transmission and connection between indoor communication devices, and do not have the performance of shockproof, dustproof, waterproof, and anti-drag; or a protective shell is simply added outside the MPO / MTP plug. The housing of the male plug and the housing of the female plug are rotated 90° and clamped. Although they have a certain degree of dustproof and waterproof performance, the poor adaptability between the plugs leads to a large loss of optical transmission, and it is prone to automatic loosening during bumps and vibrations. Signal transmission structure is unstable and unreliable
