How much pulling force should you apply in fiber optic cable installation?

Exactly how much pulling force should be used for fiber optic cable installation? Here is a brief answer. The pulling force must be kept below a designated limit for the specific cable being installed. For outside plant (OSP) fiber optic cables, the limit is usually 600 pounds. For indoor fiber optic cables and other types of cables, the limit is usually 300 pounds. The key point is – Keep the pulling force UNIFORM. Why is keeping pulling force uniform so critical? The short answer is that most fiber optic cables cannot handle high impact load. Fiber optic cable strength member is

Avoiding Disaster in Fiber Optic Cable Pulling

The basic techniques for pulling fiber optic cable differs little from the approach used to pull copper or aluminum. However, fiber responds differently than copper or aluminum when pulled. Caution One: Avoid Measurement Error! The first step in pulling fiber optic cables is to measure and cut the material. Inaccurate measurements are a disaster in fiber cable installation. Fiber optic cable splices are way more critical than metal cable splicings. Minimum loss budget must be maintained in a fiber optic cable installation project. Thus, assumptions and guess work simply do not work. Caution Two: Do Not Exceed the Allowed Pulling

Fiber Optic Cable Installation – A Brief Review

Fiber optic cable installation is a specialized task and this is a brief review of  cable installation practices for a bunch of different applications.  You can find more Fiber Optic Technical Tutorials. Fiber Optics For Sale Co. provides Fiber Optic Cable Pulling Products for cable installation and you can also find cable pulling lubricant here. Most methods for installing optical cables have been adapted from those used for copper cables. Outdoor fiber cables are laid along rights of way leased or owned by telecommunications carriers, such as along a railroad or highway, which are well marked after the cables are

What is a fiber optic splice tray?

Splice trays are necessary for holding and protecting individual fusion splices or mechanical splices. Splice trays are available for all different kinds of splices, such as mechanical splices from 3M, Corning, AMP and Siemon company, bare fusion splices and heat-shrink fusion splices, and so on. Important! Normally splice trays should be matched to the type of splice used. A splice tray designed for holding mechanical splices usually can not be used for bare fiber fusion splices or heat-shrink fusion splices. Although there are splice holding chips you can purchase to make them work, it is not the ideal way. Standard splice

What is a fiber optic splice enclosure?

Fiber optic splice enclosures are used to protect stripped fiber optic cable and fiber optic splices from the environment, and they are available for indoor as well as outdoor mounting. Outdoor fiber optic enclosures are usually weatherproof with watertight seals. In a typical wall-mounted splice enclosure, fiber optic cable is supported by cable ties, and the cable strenght member is securely fastened to the enclosure’s support. Metallic strenght members must be grounded securely. The cable jacket(sheath) stops at the splice enclosure’s cable ties. Optical fiber tubes, individual tight buffered fibers, or pigtails are supported by the tube brackets and continue
