Study Material on Fiber Optics: Cables and Connectors – Definitions and Descriptions

Single Mode Fiber(SMF)

Used for longer distances and has smaller core size, which allows for only a single mode of travel for light signal. cover longer distances

Multimode Fiber (MMF)

Used for shorter distances and has larger core size, which allows for multiple modes of travel for the light signal. Up to 2 kms or less

Angled Physical Contact (APC) Connector

Fiber-optic connector that makes physical contact between two fiber-optic cables. It specifies an 8-degree angle to the curved end, which lowers signal loss.

Ultra Physical Contact (UPC) Connector

Fiber-optic connector that makes physical contact between to two fiber-optic cables. The fibers within a UPC are polished extensively for a superior finish and better junction integrity.
