INTRODUCTION This test describes a procedure to determine the numerical aperture of step-index, glass core, glass clad and plastic clad optical fibers (fiber material class Ic, IIa, and IIb as listed in EIA-4920000-A) from the fiber far-field radiation pattern. The...
This Standard applies to class Ia, graded-index, 50/125 μm multimode optical fiber used as a component in the manufacture of fiber-optic cable. Applications include, but are not restricted to, the following: support for short reach, high bit-rate systems in telephony,...
This procedure defines the time domain method for measuring the information transmission capacity of EIA-4920000-A Class I (glass core, glass clad) optical fibers. Various methods of reporting the results are described in the appendices, but the results shall be expressed in terms of...
This part of IEC 60793 is applicable to optical fibre sub-categories A1-OM1, A1-OM2, A1-OM3, A1-OM4, A1-OM5, and A1d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Sub-categories A1-OM2, A1-OM3, A1-OM4 and A1-OM5 apply to...
This Standard specifies the test methods for structural parameters related to the dimensions of optical fibers or jacketed optical fibers of single-mode optical fibers, silicabased multimode optical fibers, multi-component...
This drawing describes the requirements for mixed fiber optic cable for ground tactical application. The mixed fiber cable detailed in this drawing consists of two multimode and two single mode optical fibers. Buffer colors identify individual fibers.
INTRODUCTION Intent These test methods describe procedures for measuring the attenuation by substitution of short length multimode graded index and single-mode optical fiber cable assemblies. The cable assemblies have a connector on only one end of the cable (pigtail) or have...
This Standard specifies requirements for fiber ribbons (hereafter referred to as fiber ribbons) which are so manufactured that plural silica glass single-mode optical fibers and silica glass multimode optical fibers are placed side by side along a...
This commercial item description (CID) covers the general requirements for an optical fiber fusion splicer capable of performing splices with the following attributes: superior optical performance, high reliability, field-ready, and compatible with both loose tube and tight...
This document describes a measurement procedure that can be applied to determine the core diameter of EIA-4920000-A Class la multimode optical fiber having near-parabolic index profiles. Refer to FOTP-58 for the determination of core diameter from the results of this...
This specification contains requirements for a multiple-fiber, dual-window, graded-index, optical waveguide, control or communications cable intended for data and communications use at airports.
This standard describes the interconnection details for N, where N = 1, 2...12, times 64 kilobit per second connections of teleprotection equipment to digital multiplexers using optical fiber. Requirements for both physical connection and the communications timing are also included....
Intent This test procedure outlines methods for measuring both the steady state response of optical fibers and cables exposed to continuous radiation and the transient response of optical fibers and cables exposed to a pulse of radiation. It can be used to determine the...
This part of IEC 61280-4 is applicable to the measurement of attenuation of installed fibreoptic cabling using multimode fibre, typically in lengths of up to 2 000 m. This cabling can include multimode fibres, connectors, adapters and splices. Cabling design standards such as ISO/IEC...
This method i s only applicable to class I a multimode, graded index optical fibers with profile parameter, g, approximately equal to 2. The fibers may be part of a fiber optic component such as an optical transmitter, switch, coupler or cable and may be...
