Multi-core multi-channel plug-in type (MULTIFIBER PUSH ON, MPO) improved Fiber optic adapter

This creation is a multi-core multi-channel plug-in (MULTIFIBER PUSH ON, MPO) modified fiber optic adapter, especially a multi-core multi-channel plug-in type (MULTIFIBER) that can easily and quickly change polarity according to the needs of users. PUSH ON, MPO) fiber optic adapter.

In the era of today's information transmission demand explosion, fiber-optic communication has revolutionized the way information is delivered. The fiber is often provided with a connector at one end thereof, and an adapter that houses the connectors connects the two fibers together so that the fiber segments are extended. However, in terms of polarity (ie, directionality), the fiber optic adapter can be classified into Key up to Key down and Key up to Key up. The user must clearly distinguish the polarity of the fiber connector in advance to purchase the fiber adapter correctly. .

However, based on the professional point of view, the creator of the fiber optic adapters sold in the market mostly has the above two types, but many users often have the wrong polarity or do not understand how to distinguish the polarity and purchase it. Often found in the use of polarity does not match, and finally requires a return, or must re-confirm the polarity and then buy again. As a result, both buyers and sellers have caused considerable inconvenience and trouble.

In view of this, how to develop a solution that can solve the above situation is the purpose that the creator of the case wants to achieve.

The purpose of this creation is to provide a multi-core multi-channel plug-in (MULTIFIBER PUSH ON, MPO) modified fiber optic adapter, which is modified by the adapter structure and provides a polarizing member, which can be used for extraction and replacement. Different polarities are used to avoid the user's trouble of buying the adapter incorrectly because the polarity is not clearly resolved.
