Fiber Optic Glossary

E

ESCON

Enterprise Systems Connection Connector

ESCON connectors were developed by IBM for interfacing peripheral storage devices, including tape drives, to their mainframes. ESCON is a half-duplex serial interface that uses FOC.

F

FC

Ferrule Core Connector

Although the FC connector was widely used in fiber optic networks until of late, its use is dwindling fast. This connector uses a threaded container and a position locatable notch to achieve exact locating of the SMF in relation to the receiver and the optical source. Once the connector is installed, its position is maintained with total precision.

FDDI

Fiber Distributed Data Interface Connector

FDDI provides data transmission at 100 Mbps in a dual ring token local area network within a 200-kilometer range. The FDDI connector connects network equipments to a wall plug. The connector contains a 2.5mm ferrule that can mate onto ST and SC connectors by making use of adapters.

L

LC

Lucent Connector

The Lucent Connector, sometimes referred to as the Little Connector, is a small form factor FOC that uses a 1.25 mm ferrule. There are 3 different types of LC connectors.

LSH

E-2000™

E-2000 is a high performance connector which meets the highest standards by excellence in design and manufacturing processes. Only high quality and high precision materials are used to guarantee connections at the highest level.

M

MTP/MPO

Multi-Fiber Push On

MPO (Multi-Fiber Push On) cables are capped with MPO connectors at either end. MPO connector is a connector for ribbon cables with at least 8 fibers, which is designed to provide multi-fiber connectivity in one connector to support high bandwidth and high-density cabling system applications.

O

OS1

Optical Fiber - Single Mode

OS1 fiber is designed for indoor applications in structured cabling systems. It is optimized for use with optical fiber communication systems operating in the 1310 nm and 1550 nm wavelength windows.

OS2

Optical Fiber - Single Mode

OS2 fiber is designed for outdoor applications and longer distance transmissions. It has a lower attenuation than OS1 and is suitable for use in campus and metropolitan area networks.

P

PLC

Planar Lightwave Circuit

PLC splitter is based on planar lightwave circuit technology and provides a low cost light distribution solution with small form factor and high reliability.

S

SC

Subscriber Connector

SC connector is a fiber optic connector with a push-pull latching mechanism. It is widely used in datacom and telecom applications due to its ease of use and low cost.

ST

Straight Tip Connector

ST connector is a fiber optic connector with a bayonet-style coupling mechanism. It was one of the first connectors to be widely used in fiber optic networks.

W

WDM

Wavelength Division Multiplexing

WDM is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths of laser light. This technique enables bidirectional communications over one strand of fiber.
