TSD-2000-4-2-1 OPTICAL FIBRE CABLING: TESTING OF INSTALLED CABLING: LSPM Issue 4.01
In some cases, technology can move faster than national standards and a good example has been test equipment. In 2002, TSD-2000-4-2-1 was written to remind installers of the existing standards, outlining which test method to use to measure the attenuation of specific configurations of installed cabling using the older type of LSPM equipment – added to which the document defined alternative methods capable of measuring any cabling configuration with the more advanced kit that was then coming on to the market. In 2004, TSD-2000-4-2-1 began to be used by international groups during the revision of their test method standards. This, and other FIA work, led to the publication of ISO/IEC 14763-3:2006, BS EN 61280-4-1:2009 and the revision of IEC 61280-4-2 leading to an expected second edition of BS EN 61280-4-1 in 2012.
The Issue 4 of TSD-2001-4-2-1 defines the FIA Position on the use of these latest standards for the testing of installed optical fibre cabling.
