Can optical cables be branched in the middle

Home / Can optical cables be branched in the middle

A process called midspan access allows adding drops to a cable without disturbing the fibers that need to pass through the drop point. Backbone cables of 144-288 fibers are common and larger ones are becoming more common too. The present invention relates to a method for mid-span branching of optical fiber cable which makes the mid-span branching possible without excess length of the optical fiber cable by forming main branching part and sub branching part for branched cores to be taken out from an existing main cable. In fiber optic network, it is sometime necessary to splice large fiber count cables to smaller cables at a location other than at the end of the large cable, called mid-span entry. This application note provides guidelines on how to access fibers/ribbons at mid-point of Sterlite optical fiber. NOTE: The below considerations are not intended to encompass all installation practices.
