適用范圍：This specification contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements of a fully installed blown fibre ‘microduct’ connector in order for it to be categorised as an EN standard product.This product specification covers the following ‘microduct connectors’ to suit a wide range of blown fibre applications, for floating or fixed:? joining the same size microduct, or different sizes of microduct;? joining same size protected microduct, to same or different size of microduct or protected microduct;? disconnection of the connector to gain access, for example, to insert blowing equipment;? a means to seal the fibre inside the connector to prevent the flow of liquids;? close off open-ended microducts.This product specification covers blown fibre microduct connectors for use in ‘sub-ducts or protected micro-duct cable closures’ as specified in EN 50411-2-5 for use in outside environments, and for both sealed and nonsealed closures. The outside environment includes both subterranean (underground) and/or aerial applications.This document includes reducer/enlarger products. It may not be possible to blow through these devices.Manual feeding may be required because of the pressure gradient step.This product specification does not apply to microduct connectors for use in direct sunlight.
