Fiber Optics Installations

10/25/2013

This is a relatively good fiber optics outdoor jointing closures installation.
The jointing closure is mounted to the telephone pole with proper mounting bracket designed for pole installation.

Let us take a look at others outdoor fiber optics jointing installation.
By looking at these photos one might come to the conclusion that lack of Attitudes, Skills and Knowledge contributed to these bad installations !!

Isoprophyl Alcohol

Isoprophyl alcohol is used extensively in fiber optics to get rid of dirt, dust and other contaminants during the the termination or jointing of fiber optics cable.
Isopropyl alcohol is a skin irritant. It should be kept away from heat and open flame.
Poisoning can occur from ingestion, inhalation, or absorption. Therefore it is highly recommended to use isoprophyl alcohool in a well-ventilated areas.
Smoking and eating are both strictly a big NO..

What is Fiber Optics ?

Basically, fiber optics is made from glass and contains 3 main structures.
a. Core
b. Cladding
c. Buffer

Light travels inside the fiber optics core..

The cladding causes light to be confined to the core of the fiber by total internal reflection at the boundary between the two due to differences in refractive index between fiber core and cladding.
The cladding refractive index (n1) is lower than fiber core refractive index (n2)

The buffer is basically made from plastic to provide addtional protection to both fiber optics and cladding.

During the process of splicing or jointing fiber optics, the buffer which is of size 250micron will be removed. This process is called stripping.

Stripper is used to strip off fiber optics buffer

Fiber Optics - Color Blind Test

If you are a color blind person, it would be most difficult for you and your team to do fiber optics fusion splicing or termination in sequence.

Why ?

Because fiber optics has 12 color coded as per TIA/EIA 598-A. The color coded in sequence is :-

1 Blue
2 Orange
3 Green
4 Brown
5 Gray
6 White
7 Red
8 Black
9 Yellow
10 Purple
11 Rose
12 Aqua

Color Blind Test
If you have a normal color vision, you will be able to see 73.
If you are colorblind you will have difficulty to see 73.
