Title: Launched Power Distribution Measurement Procedure for Graded- Index Multimode Fiber Transmitters

Abstract  This FOTP sets forth a standard procedure for the collection of two-dimensional fiber optic nearfield grayscale data and subsequent reduction to one-dimensional data expressed as a set of three sampled parametric functions of radius from the fiber’s optical center. This standard is intended to reduce measurement errors and inter-laboratory variation, supporting accurate mathematical prediction of minimum guaranteed link length in gigabit and ten gigabit fiber optic data communications systems.

Title: Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 3-43: Examinations and measurements – Mode transfer function measurement for fibre optic sources.

Abstract This part of IEC 61300 describes the method for measuring the mode transfer function (MTF) to be used in characterizing the launch conditions for measurements of attenuation and or return loss of multimode passive components, according to IEC 61300-1 and IEC 61300-3-4. The MTF may be measured at the operational wavelengths

Standards relevant to measurements of optical fiber cables and components

Number: IEC 61280-4-1

Title: Fiber-optic communication subsystem basic test procedures – Part 4-1: Test procedures for fiber-optic cable plant and links – Multimode fiber-optic cable plant attenuation measurement

Establishes preferred measurement principles and practices to assure that meaningful data describing the optical loss performance of installed cable plants can be obtained. It is not intended for component testing, it does not define those elements of an installation that need to be measured. This procedure is a specific test associated with IEC 61281-1. This procedure can be used to measure the optical loss between any two passively connected points, including end terminations, of a multimode optical fibre cable plant.

Title: OFSTP-14 Optical Power Loss Measurement of Installed Multimode Fiber Cable Plant.

This procedure can be used to measure the optical loss between any two passively-connected points, including end terminations, of a multimode optical fiber cable plant. The optical fiber cable plant, as the term is used here, may consist of optical fiber cables, connectors, mounting panels, jumper cables, and other passive components, but may not include active components. An example of the cable plant could be a portion of an LED-based local area network. This could include optical switches or couplers, but would exclude gain elements in the connected path.

Number:  ISO/IEC 11801 – Ed. 2.0

Title: Information technology – Generic cabling for customer premises

Abstract Within customer premises, the importance of the cabling infrastructure is similar to that of other fundamental building utilities such as heating, lighting and mains power. As with other utilities,interruptions to service can have a serious impact. Poor quality of service due to lack of design foresight, use of inappropriate components, incorrect installation, poor administration or inadequate support can threaten an organisation’s effectiveness.

Historically, the cabling within premises comprised both application specific and multipurpose networks. The original edition of this standard enabled a controlled migration to generic cabling and the reduction in the use of application-specific cabling. This second edition of ISO/IEC 11801 has been developed to reflect the increased demands and opportunities which have arisen since — and are partly the result of — publication of the first edition in 1995.
