TIA标准化委员会制定的新的用于光缆测试的规范TSB-140旨在澄清568-B.3中关于测试方面的规定。这个规范在意义上非常象当年的TSB-67和TSB-95(注:TSB-67和TSB-95规范被用来澄清非屏蔽双绞线中5类和超5类测试程序,并且TSB-67曾经是非屏蔽双绞线布线系统现场测试规范的里程碑)。TSB-140就是要去除人们对光纤链路要进行什么样的测试和如何进行测试的疑惑。 在国际上,TIA和ISO两大标准组织都已经在很多的其它标准中制定了相关的光纤测试程序。TIA568-B.3中参考了这些程序,但是TSB-140是要制定
The new TSB-140 specification for optical cable testing developed by the TIA Standardization Committee aims to clarify 568-B.3 provisions on testing. This specification is much more in the sense of the current TSB-67 and TSB-95 (Note: The TSB-67 and TSB-95 specifications are used to clarify Category 5 and Category 5 test procedures for unshielded twisted pair, and TSB-67 Used to be a milestone in field testing of unshielded twisted pair cabling systems. TSB-140 is to remove people on the optical link to what kind of test and how to test the doubts. Internationally, both the TIA and ISO standards organizations have developed the relevant optical fiber testing procedures in many other standards. These procedures are referenced in TIA568-B.3, but TSB-140 is to be developed
