目前在现场和实验室能够简便地测量光缆损耗和色散,当归功于法国Wild Heerbrugg公司制造的一种新型光纤连接设备——Wild M 540。该设备由 Wild Heerbrugg公司根据法国国际电信联盟(CCITT)标准与瑞士PTT公司联合研制而成,它宜于连接多模渐变型折射率和阶跃型折射率光纤以及单模光纤,连接效率高达95.5％±2.2％,相当于0.2dB±0.1dB的损耗。 At present, it is easy to measure optical cable loss and dispersion in the field and in laboratories, thanks to the Wild M 540, a new type of optical fiber connection equipment manufactured by Wild Heerbrugg in France. The device, developed by Wild Heerbrugg in cooperation with PTT AG in accordance with the French National Telecommunications Union (CCITT) standard, is suitable for connecting multimode graded-index and step-index fibers as well as single-mode fibers with connection efficiencies up to 95.5 % ± 2.2%, equivalent to 0.2dB ± 0.1dB loss.
