Will a preterminated fiber assembly pass through innerduct?
A fiber trunk can fit on paper while its pulling eye or protected fan-out cannot clear a bend. Ask the assembly supplier for the largest outside dimension of the assembly as delivered for pulling.
What should I measure besides the cable jacket?
Give the pathway designer the cable diameter, pulling head, bend requirements and proposed turn sequence. The catalog’s nominal one-inch innerduct identifies a product family. Confirm the usable internal dimension from the model specification and account for other cable already in the path.
Is pull tape part of the duct?
Some descriptions explicitly include tape, while a roll described as polyester pull tape is an accessory. Compare the entire kit against the installer’s plan. The cable’s own pulling limits still govern how the optical assembly can be handled.
Can the receiving team verify a preterminated assembly in advance?
Ask for the packaging drawing showing the pulling head and protected branch lengths. Share it with the pathway designer along with any intermediate access points. The maximum width may occur several inches behind the leading tip, which a close-up of the first connector can easily miss.
Allow for a factory-terminated fiber assembly
A trunk with factory-installed ends can require considerably more pathway space at its pulling head than along its jacket. Ask the assembly supplier for pulling-head dimensions, bend limits and installation requirements, then compare them with the proposed innerduct and access points. The one-inch 12CD-01250 comes with pull tape; the tape rating and the assembly’s allowable pulling load are different specifications. On a route with several turns, have the installer evaluate those turns before ordering the trunk. Record a diagram with each access point so a future fiber upgrade can use the same pathway information.
Comparing field termination with a protected factory fan-out
A contractor proposing bulk cable may plan to pass the jacketed cable through the innerduct and make terminations afterward. A supplier proposing a preterminated trunk may ship several finished connectors inside a larger protective assembly. Ask each to describe the largest object that must pass through the tightest section and where breakout legs are protected during installation. Give the pathway designer both proposals and the enclosure access details. A choice that saves termination time may require a different pulling arrangement or access point. Compare the total accepted job, including termination, testing and any pathway changes, before choosing one approach. If a pull tape already exists, have the installer confirm that its condition and rating suit the approved operation. A tape left from an old project does not prove a new assembly will pass.
