Fibre engineers and network owners are increasingly insisting on 100% mechanically sealed closures. Traditional heatshrink methods for cable sealing are time consuming; dependent on the skill of the engineer; and the access required around the port means heatshrink is not conducive to high port densities, particularly applicable in today's FTTX environment. There are also health and safety concerns relating to gas bottle storage/transportation and HellermannTyton's patented Cablelok™ mechanical seal enables fast safe cable installation, providing a highly repeatable and consistent seal between...

Selecting the Correct Cablelok™ Each port size on the HellermannTyton closures has a unique identifier and a dedicated series of Cableloks (ie: R, B, S, T, LM or L). Every Cablelok™ within a series is specifically designed to accommodate a range of cable diameters. Achieving the required seal performance is simply a case of selecting the correct Cablelok™ for the port and cable combination being used. Step 1: Determine the diameter of the cable being used. Step 2: Choose the appropriate closure port to be used and hence port identifier. Step 3: Identify the correct Cablelok™ using the port and...
