A tool for access to optical fibres contained within a cable includes: a body having a longitudinal recess along a longitudinal axis, conceived to partially contain a section of cable; and a blade having a cutting edge fixed transversally inside the recess set at a predetermined slant in relation to the longitudinal axis of the recess. The method of the present invention sufficiently advances the signal to compensate for the time delay induced by communication signal travel over a fiber optic connection between a base station cellsite and a remote microcell. The surface further has a crimping recess spaced apart from the receiving hole. The electrically conductive nest includes an enclosure portion enclosing the bridge controller PCB with a conductive grounding tab in contact with the host interface connector.
