38、IA/EIA-455-41A Page 10 c APPENDIX COMPARISON BETWEEN FOTP-41 AND IEC, SIO, AND CCITT REQUIREMENTS (Nonmandatory Information) B.l IEC Reference is made to IEC 794-1, Second Edition (1987), “Optical fibre cables, Part 1: Generic Specification,“ and to IEC 794-2, Second Edition (1989-lo), “Optical fibr
39、e cables, Part 2: Product specifications. I Clause 12 of IEC 704-1 covers “Method IEC 794-1-E3 - Crush,“ which is a method essentially the same as FOTP-41. IEC 794-1 reqires testing at 15 to 35OC, 25 to 75% relative humidity, and 86 to 106 kPa air pressure, which does not completely agree with FOTP-
40、41. IEC 794-1 also specifies that if the load is applied in incremental steps, the steps shall not exceed a ratio of 1.5:l. IEC 794-1, like FOTP-41, defers to the Detail Specification for other test conditions and requirements. As examples of Detail Specification requirements, Clause 6.2 of IEC 794-
41、2 deals with a single fiber cable. It calls for a minimum radius of curvature of the movable plate of 5 mm, and a 500 N load applied for 1 minute, with no fiber breakage allowed. Clause 10.2.2 relates to a dual fiber cable; it calls for a minimum of a 5 mm radius movable plate curvature, and a 1000
42、N load applied for 1 minute, with no fiber breakage allowed. B.2 IS0 No comparable IS0 tests have been identified or reviewed. B.3 CCITT It should be noted that, as of this publication date, there are no known CCITT test methods that are comparable to this FOTP. Copyright Electronic Industries Allia
