Definitions of Terms used in Fibre Optic Cable

1. Terminations

• Patch panels:-

  Provides a centralized location for patching fibres, testing, monitoring and restoring cables.

• Connector:

   A non-permanent device for connecting two fibres or fibres to equipment where they are expected to be disconnected occasionally for testing or rerouting. It also provides protection to both fibres.

• Ferrule:

  A tube which holds a fibre for alignment, usually part of a connector

• LC Connector

LC stands for Latched Connector and its interconnect is based upon the RJ-45 telephone interface. The LC Connector uses Zirconia ceramic ferrules in a free-floating and pull proof design.

• SC connector

SC Stands for Single Coupling. It is Square shaped snap-in connector that latches with a simple push-pull. The SC connector has the advantage (over ST) of being duplexed into a single connector clip with both transmit/receive fibres.

• MU Connector

The MU stands for Miniature Unit fibre-optic connector, which features compact size, high packaging density, and high performance and a simple push-pull design. The MU connector ferrules are half the size of the standard FC, SC connectors and are excellent for high density installations.

• ST Connector

ST Stands for Straight Tip. The ST connector is spring-loaded bayonet mount and have a long cylindrical ferrule to hold the fiber.

• FC Connector

The FC stands for "Face Contact" The anti-rotation key prevents fibre end face damage and rotational sensitivity and the floating ferrule prevents shock and vibration.

• PC Connector

Physical Contact Connector

• FPC Connector

Flat Physical Contact Connector

• APC Connector

Angled Physical Contact Connector

Super Physical Contact Connector

• UPC Connector

Ultra Physical Contact Connector
