:: Duct / Innerduct materials and colors:

Gaines fiber are usually made from HDPE (polyethylene high density), PVC or other compounds. They are usually black or gray. Innerduct fiber is usually orange or yellow.

:: Why generally ducts and innerducts fibers are wavy?

Fiber ducts and innerducts are corrugated to provide the following services:

1. Defusing tensions traction during installation

2. Very flexible and can be used in installation locations which turns many are involved

3. After installation, corrugated innerduct should be left for a day to allow the innerduct to retreat back into the channel through its corrugated Spring Action

:: The use of traction strips

Fiber optic cable pulling tape is pre-installed in the duct and innerduct fiber in the plant. This saves significant time during the installation process. Duct and innerduct can also be pre-lubricated at the factory, which significantly reduces tension traction.

:: Never bend its minimum radius of curvature

Like fiber optic cable, fiber channel and innerduct also have a minimum radius of curvature spec. Never ever should the duct or innerduct be bent tighter than its minimum bend radius.

:: Radius What is covered?

The load radius is the minimum radius of curvature when the pipe is wound around a second structure, as in a another channel or spool.

:: What is the radius unsupported?

The radius is not supported is the minimum radius of curvature when the duct has no support structure in the corner.

:: The advantages of using fiber sheaths

Fiber jacket protects the fiber cable and also provides an opportunity for cable access and future development. The optical cable may be pulling in the existing channel. The channel should normally be oversized to allow for future cables to be pulled in.

:: Benefits using fiber innerduct

Fiber Innerduct provides protection for the fiber cable to be disturbed by the installation operations other cable companies. It also provides extra protection of the environment. Innerduct or fiber can be used in installation old leads.

:: Things to remember

1. End to install catch

After the cable Fiber optics is installed in a duct or innerduct, end caps must be installed to ensure water tightness. No debris should be able to enter the channel or innerduct, and is impervious to water must always be maintained for the conduct or innerduct.

2. Duct and innerduct must be properly sized for possible future expansion

As always, planning for expansion future is crucial for real projects successfully. A maximum of 40% filling ratio is a good practice to follow. The size of the pipe should be increased for lengths of the facility along with several towers. A larger pipe may help to reduce tensions pulling cable. Conduit standard sizes vary of 3 at 8 ID inch innerduct sizes vary from 0.75 to 2 inches.

:: The advantage of using a lubricant leads

Duct lubricant can significantly reduce the power coefficient of friction, which reduces the tension by pulling in cable pulling process. This is particularly important conduit for cable length of pull and pull with several towers.

Duct leakage of lubricant must be cleaned up as soon as possible avoid the accident because it is very slippery. Manufactures recommended procedure 'for cleaning lubricant provides good instructions on how to clean.
