The use of pre-connectorized cables is particularly significant. Although the use of factory-terminated cross-connection assemblies and jumpers is acceptable, the use of a pre-connectorized backbone and distribution cable presents special installation techniques. These connectors need protection when installing the connected end of these cables. Protective handles are available to protect the connectors, but the external diameter of the handle can prevent installation in small ducts or conduits.

When pulling long lengths of wire onto a duct, a fill rate of less than 50% per cross-section is recommended. For instance, a cable is equivalent to a 0.71 inch outside diameter cable in a 1 inch inside diameter conduit. Several cables can be pulled at the same time since the pull load is applied equally to all cables. Filler ratios can dictate higher fiber counts for future requirements. A jacket can be more compact with fibers than several cable covers.

If future cable runs in the same duct or conduit are a possibility, the use of the innerduct to sectionize the available duct space is recommended. Without this sectionalization, additional cables may become tangled and cause a service disruption. Where the cable is installed in cable trays, cable trays or attached to other cables, the movement of existing cables should be considered. Although the fiber optic cable can be moved into service without affecting the performance of the fiber, it may warrant conduit protection in areas exposed to physical damage.
