How Do You Protect Fiber Optic Cable?

The protection of optical cable lines is one of the most important contents in the engineering design of fiber optic cabling solutions because it is related to the safety and service life of optical cable lines. The protection of optical cable lines mainly includes lightning protection, strong current protection, termite protection, rat-bite protection, antifreeze protection, and mechanical damage protection.

Lightning protection of optical cable line

The lightning strike is one of the main causes of communication cable failure. In principle, there is no lightning protection problem for the optical cable without metal components, but in order to prevent mechanical damage, strengthen the mechanical strength of the optical cable and save the engineering cost, the optical cable with metal components (metal reinforced core, metal moisture barrier or metal armor) is generally used. Therefore, the problems of lightning protection and strong current protection of optical cable lines must be considered in the project construction.

Anti strong current of optical cable line

In order to find the protective measures, it is necessary to first understand the classification of strong current lines, the classification of strong film noise, and the allowable standard of strong current influence, and then discuss the protective measures.

Antifreeze protection of optical cable line

In cold regions, due to the difference of climatic conditions and seasonal climate change, permafrost or seasonally frozen soil appears in cold regions. When laying cabling products in these areas, if the buried depth is not selected properly or the optical cable is not selected properly, there may be seasonal optical cable line failure. Therefore, in cold areas, anti-freezing measures should be taken according to different climatic characteristics and frozen soil conditions.

What Are the 2 Types of Fiber Optic Cable?

Classification by optical fiber material

According to the material of optical fiber, optical fiber can be divided into quartz fiber and all plastic fiber.

Quartz fiber is generally composed of doped quartz core and doped quartz cladding. This kind of fiber has low loss and medium dispersion. At present, most of the optical fibers used in communication are quartz optical fibers.

All plastic optical fiber is a new type of optical fiber for communication, which is still in the stage of development and trial. All plastic fiber is characterized by high loss, large core diameter (100-600 μ m), large numerical aperture (NA) (generally 0.3-0.5, which can be coupled with a light source with large spot), and low manufacturing cost. At present, all plastic optical fiber is suitable for short-length applications, such as indoor computer networking and ship communication.

Classification by refractive index distribution of fiber profile

According to the different refractive index distribution of optical fiber profile, the types of optical fiber can be divided into step optical fiber and gradient optical fiber.

Classification by transmission mode

According to the number of modes of optical fiber transmission, the types of optical fiber can be divided into multimode fiber and single-mode fiber.

Single-mode fiber can only transmit the fundamental mode (the lowest order mode), there is no inter mode delay difference, and it has a much larger bandwidth than multimode fiber, which is very important for high code rate transmission. The mode field diameter of single-mode fiber is only a few microns(μm) Its bandwidth is generally one or two orders of magnitude higher than that of tapered multimode fiber. Therefore, it is suitable for large capacity and long-distance communication.
