This document covers the performance specification for electroabsorption (EA) type optical modulators monolithically integrated with laser diodes for 40 Gbit/s fibre optic transmission systems. This performance standard contains a definition of the product performance requirements together with a series of sets of tests and measurements with clearly defined conditions, severities and pass/fail criteria. The tests are intended to be run as an initial design verification to prove any product’s ability to satisfy the performance standard’s requirements. This standard is applicable for on-off keying format.

A product that has been shown to meet all the requirements of a performance standard can be declared as compliant with the performance standard but should then be controlled by a quality assurance program.

This part of IEC 62614 describes the launch condition requirements used for measuring multimode attenuation in passive components and in installed cable plants.

In this document, the fibre types that are addressed include category A1-OMx, where x = 2, 3, 4 and 5 (50 mm /125 mm), and A1-OM1 (62,5 mm /125 mm) multimode fibres, as specified in IEC 60793-2-10. The nominal test wavelengths detailed are 850 nm and 1 300 nm. This standard may be suitable for multimode attenuation measurements for other multimode categories and/or other wavelengths, but the source condition for other categories and wavelengths are not defined here.

The purpose of these requirements is as follows:

to ensure consistency of field measurements when different types of test equipment are used;

to ensure consistency of factory measurements when different types of test equipment are used;

to ensure consistency of field measurements when compared with factory measurements.

This document describes launch condition requirements for optical attenuation using sources with a controlled encircled flux (EF).

This part of IEC 61290 applies to all commercially available optical amplifiers (OAs) and optically amplified modules. It applies to OAs using optical fibre amplifiers (OFAs) based on either rare-earth doped fibres or on the Raman effect, semiconductor OAs (SOAs) and planar optical waveguide amplifiers (POWAs).

The object of this standard is to establish uniform requirements for accurate and reliable measurements, by means of the optical spectrum analyzer (OSA) test method, of the following OA parameters, as defined in IEC 61291-1:

nominal output signal power;

< >

polarization-dependent gain (PDG);

maximum output signal power;

maximum total output power.

In addition, this standard provides the test method of:

gain ripple (for SOAs).

NOTE All numerical values followed by (‡) are suggested values for which the measurement is assured.

The object of this standard is specifically directed to single-channel amplifiers. Test methods for multichannel amplifiers are standardized in the IEC 61290-10 series [1][1].

This part of IEC 61300 describes the test procedure to test the wind resistance of a protective housing and its mounting hardware using the fastening parts recommended by the manufacturer. The protective housing is considered to have a cuboid shape.

The applied force in this test procedure simulates a steady wind load from each direction to a protective housing and its mounting hardware fixed to a support.

This part of IEC 61280 is applicable to the measurement of attenuation and determination of polarity and length of installed multimode and single-mode optical fibre cabling plant, terminated with MPO connectors, using test equipment having an MPO interface. This cabling plant can include multimode or single-mode optical fibres, connectors, adapters, splices, and other passive devices. The cabling can be installed in a variety of environments including residential, commercial, industrial, and data centre premises, as well as outside plant environments.

In this document, the optical fibres that are addressed include sub-categories A1-OMx, where x = 2, 3, 4 and 5 (50/125 μm) multimode optical fibres, as specified in IEC 60793-2-10, and category B-652 and B-657 (9/125 μm) single-mode optical fibres, as specified in IEC 60793-2-50. The attenuation measurements of the other multimode and single-mode categories can also be made using a light source and power meter (LSPM) or optical time domain reflectometer (OTDR) utilising an internal or external optical switch having one MPO interface. Multimode measurements are made with an 850 nm source because transceivers used for parallel optics applications having an MPO interface only operate at 850 nm; 1 300 nm measurements are optional. Single-mode measurements are made with a 1 310 nm and/or 1 550 nm source because transceivers used for parallel optics applications having an MPO interface operate at these wavelengths. This document does not include descriptions of cabling that is not exclusively MPO to MPO.

This document applies to the family of fibre optic filters. These components have all of the following general features:

they are passive for the reason that they contain no optoelectronic or other transducing elements which can process the optical signal launched into the input port;

they modify the spectral intensity distribution in order to select some wavelengths and inhibit others;

they are fixed, i.e. the modification of the spectral intensity distribution is fixed and cannot be tuned;

they have input and output ports or a common port (having both functions of input and output) for the transmission of optical power; the ports are optical fibre or optical fibre connectors;

they differ according to their characteristics. They can be divided into the following categories:

short-wave pass (only wavelengths lower than or equal to a specified value are passed);

long-wave pass (only wavelengths greater than or equal to a specified value are passed);

band-pass (only an optical window is allowed);

notch (only an optical window is inhibited);

gain flattening (compensating the spectral profile of the device).

It is also possible to have a combination of the above categories.

This document provides the generic information including terminology of IEC 61753-04x series documents. Published IEC 61753-04x series documents are listed in the Bibliography.

This document establishes uniform requirements for the following:

optical, mechanical and environmental properties.
