SC/UPC Duplex Adapter Connector

The SC/UPC Duplex Adapter Connector, sometimes also called SC/UPC coupler, is a small passive device in the telecommunication field. It ends or links the fiber optic cables or fiber optic connectors between two fiber optic lines. By linking two connectors precisely, they allow the light sources to end at most and lower the loss as much as possible.

Fiber Optic Adapters and Fast Connectors


Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad).


Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables.
