This Technical Report defines the term “drop cable”, describes the application spaces and the performance requirements as a consequence of the different applications. Cable design options which result from specific applications which are not yet described in the existing product specifications will be explained.<\/p>\n
This technical report also gives some guidance on cable testing with focused attention on cable performance requirements which are not covered by existing standards yet.<\/p>\n
This technical report is not intended to be used as a product standard.<\/p>\n
