Glossary

(1) A permanent joint between two optical waveguides. (2) Fusing or mechanical means for joining two fiber ends.

A cabinet used to organize and protect splice trays.

A container used to organize and protect spliced fibers.

A wiring error in twisted-pair cabling where one of a pair

Generic term for a passive device that splits one RF transmission path into two, normally full band (3dB loss)

The ratio of power emerging from two output ports of a coupler.

The emission of random photons (incoherent light) at the junction of the p and n regions in a light-emitting diode when current flows through it. Occurs when a semiconductor accumulates spurious electrons. Spontaneous emission interferes with coherent transmission

Supply Request Form – details the required free issue equipment / materials.

A measurement of the impedance uniformity of a cable. It measures energy reflected due to structural variations in the cable. The higher the SRL number, the better the performance; this means more uniformity and lower reflections.

A fiber-optic connector with a bayonet housing; it was developed by AT&T but is not in favor as much as SC or FC connectors. It is used with older Ethernet 10Base-FL and fiber-optic inter-repeater links (FIORLs).

An LED or laser diode that emits light with a controlled and constant spectral width, central wavelength, and peak power with respect to time and temperature.

Stamp and Form Contact - The contact pin is formed into its shape from the sheet of material by using a press tool.

Mutually agreed-upon principles of protocol or procedure. Standards are set by committees working under various trade and international organizations.

A fiber-optic coupler in which power at any input port is distributed to all output ports. Star couplers may have up to 64 input and output ports.
