本临时欧洲电信标准（I-ETS）规定了单模光纤通信陆基（非潜艇）系统中使用的熔合接头的要求。该范围包括制定以下方面的最低UNFM要求:-光学、环境和机械性能；-试验条件-验收标准。一些用户可能有额外的具体要求，例如需要在较低温度下验证性能。这些用户应指定符合基本ETSI性能标准的切片，以及附加测试或更严格的测试条件。出于鉴定的目的，拼接被定义为由切片保护器保护的熔接光纤，在拼接保护器的每侧有1.5 m的光纤尾端。在所有气候和环境试验的试验条件下，拼接保护器每侧的最小长度必须为1.5 m。

This Interim European Telecommunication Standard (I-ETS) specifies requirements of fusion splices to be used in single-mode optical fibre telecommunications land based (not submarine) systems. The scope includes the establishment of minimum unform requirements for the following aspects: - optical, environmental and mechanical properties; - test conditions, - acceptance criteria. Some users may have additional specific requirements, such as a need to verify perfprmance at lower temperatures. These users should specify slices conforming to the basic ETSI performance standard, plus additional tests or more severe test conditions. For the purpose of qualification, a splice is defined as fusion spliced fibres protected by a slice protector with fibre tails of 1,5 m on each side of the splice protector. A minimum length of 1,5 m on each side of the splice protector must be exposed to the test conditions of all climatic and environmental tests.
