Fiber Optic Pull Box Distance

If you are only planning to pull optical fiber cables a common industry practice is to place the handholes or pull boxes up to 450 m 1500 ft apart.

Fiber optic pull box distance.

On long runs use proper lubricants and make sure they are compatible with the cable j. Om3 has the same 300 meter distance limit as om1 but is also capable of transmitting data ten times faster at 10gb. You should pull on the fiber cable strength members only. Om4 multimode fiber optic 550 meters.

Inspect the cable run to ensure there are no sharp bends or corners that exceed the minimum bend radius of the fiber. In many runs if the pulling distance is short enough and the pathway straight enough fiber optic cable can be pulled by hand without the use of special equipment. Om3 multimode fiber optic 300 meters. Procedures for pulling fiber optic cable.

Ready to pull fiber optic pre terminated assemblies are a great solution for indoor indoor outdoor and outdoor runs and are available in singlemode and in multimode 62 5 125 om1 50 125 om2 and 50 125 om3 cable types. Determining the size of underground pull and junction boxes to meet nec 314 16 code standards is required to prevent damage to conductor insulation. However first make sure the pull does not exceed the tensile loading limit established by the manufacturer for installation. 2 in many runs if the pulling distance is short enough and the pathway straight enough fiber optic cable can be pulled by hand without the use of special equipment.

A new fiber optic installation standard. Regarding the pathway choices the use of galvanized steel conduit is not a common practice in such installations.

Om4 carries a 10gb up to 550 meters providing a distance upgrade to om3 similar to how om2 has the same speed but a greater maximum length than om1.
