Installation of optical cable supports in tunnels

Home / Installation of optical cable supports in tunnels

In order to support the cable while being transported through the tunnel it would be necessary to either: Install rollers on the cable support steelwork and intermediate supports, as used during conventional winch and bond pulling. 100 describes characteristics, construction, test methods, and performance criteria of optical fibre cables installed by pulling method for duct and tunnel application. It forms a critical backbone for modern communication networks across both urban and rural environments. Our consoles for central support can be fitted to threaded rods, rock bolts or pendular channels.
