How to Identify Fiber Optic Cable?

2017-02-04

Fiber Optic Cable How Identification

Structurally, fiber optic cables are more complex than what we just see, a fiber optic cable involves 8 kinds of materials at least . Furthermore, different fiber optic cables include different materials and designs which make them a little bit costly. So there are many inferior cables in the market supplied at low price, which gives people difficulties to get high-quality products. But it is still able to identify by the appearance and performance, as bad materials would cause evidence on products.

Below are listing some useful experiences from the structure of fiber optic cable to give you ideas for identification.

Outer skin

For outdoor and indoor fiber optic cables, we can identify from appearance’s features by below:

Appearance of high quality

Appearance of poor quality

Outdoor optical cable

smooth, bright, pliable

poor finish, sticky

Indoor optical cable

flat, no bubbles, bright, even

rough, uneven

Optical fibers

Good fiber optical cables were with A grade fiber core, while in poor fiber optical cables, C or D grade or even illegal fibers are usually used. And because fibers are inside the cables, It’s not likely to identify the fibers from eyes. However, poor fibers would cause many troubles in performance, they almost can not support long distance transmission or large bandwidth. And they looks lack of uniformity and flexibility in appearance and easily break.

Strength steel

High-quality cable

gray, stainless, strong

Conclusion

Differences between good products and inferior products not only lie in the price, also this article gives experienced points about differences from structure of fiber optic cable to identify.
