Case Study

Relocation of CCTV Camera & Single-Mode Splicing & Testing

During the development of a new building at Farnborough Business Park in March 2015, an existing CCTV camera position was obstructive and required relocation. The Construction Civils team provided a new concrete base, the necessary underground ducts, and the lifting capability to relocate the pole. Our scope was to provide the fibre splicing and cabling to support the move.

The single-mode fibre optic cabling for all of the other cameras in the park actually ran through the camera base, so it was required to fusion splice a new fibre optic external joint into the ring at a footway chamber position. From this position, we installed and connected a new 4 core single-mode cable to the relocated camera position, approximately 100m away.

Upon completion of the splicing, some of the cameras did not come back up – our diagnostic OTDR equipment and inspection tools on site at this point became invaluable. We identified: dirty connector faces at the security office patch panels, which were causing transmission and telemetry control issues; damaged ferrules at the patch panels causing misalignment of the fibre cores and loss of connections; plus, one media converter pair would not come back to life after the cutover. We stayed on site with the client until all issues were resolved.
