Transmission and Multiplexing (TM); Functional and system parameters; Passive optical components; M x N fibre branching devices functional specifications
This Interim European Telecommunication Standard (I-ETS) applies to balanced fibre branching devices to be used in single mode optical transmission networks. Unbalanced fibre branching devices should satisfy similar mechanical and environmental requirements. The scope is to establish minimum uniform requirements for the following aspects: - optical, environmental and mechanical properties; - test conditions; - acceptance criteria.
