How to identify and understand optical cable nomenclatures


Depending on the type of application they are intended for, fiber optic cables are classified into the following groups of families:

a) optical cables for buried installations;
b) optical cables for installations in ducts or for aerial installations by spinning;
c) self-supporting optical cables for aerial installations;
d) self-supporting optical cables for aerial installations in long spans;
e) optical cables for network terminations;
f) optical cables for indoor installations;
g) optical cords;

Below is a brief description of each type of cable:

DIELECTRIC OPTICAL BURIED CABLE (DE):
Set consisting of single-mode or multimode type optical fibers graded-index coated in acrylate, with protection elements of the basic unit, dielectric traction element, eventual fillers, and core filled with a material resistant to the penetration or propagation of moisture, protected by an internal coating of thermoplastic material, an additional polyamide coating and an outer coating of thermoplastic material. It should preferably be applied buried in direct contact with the soil.

BURIED PROTECTED DIELECTRIC OPTICAL CABLE (DPE):
Set consisting of single-mode or multimode optical fibers graded index, coated in acrylate, protection elements of the basic units, dielectric traction element, eventual fillers; and core filled with material resistant to the penetration or propagation of moisture and protected by a thermoplastic material coating, over which a polyamide coating and an external protection composed of a thermoplastic material duct are applied. It should be applied preferably buried, in direct

The first transatlantic telephone cable to use optical fiber

The first transatlantic telephone cable to use optical fiber was TAT-8, based on Desurvire optimised laser amplification technology. It went into operation in 1988. Third-generation fiber-optic systems operated at 1.55 μm and had losses of about 0.2 dB/km. This development was spurred by the discovery of Indium gallium arsenide and the development of the Indium Gallium Arsenide photodiode by Pearsall. Engineers overcame earlier difficulties with pulse-spreading at that wavelength using conventional InGaAsP semiconductor lasers. Scientists overcame this difficulty by using dispersion-shifted fibers designed to have minimal dispersion at 1.55 μm or by limiting the laser spectrum to a single longitudinal mode. These developments eventually allowed third-generation systems to operate commercially at 2.5 Gbit/s with repeater spacing in excess of 100 km (62 mi). fiber optic technician certification The fourth generation of fiber-optic communication systems used optical amplification to ...

What are backlinks

 First of all, it’s necessary to sort out “what is a backlink”. There is no need to explain everything in detail. The main thing to understand is what it is for and how it works. A backlink is a kind of Internet manipulator. It links one particular site with other external websites which contain links to this site. In other words, when you visit external sites they will lead you to that particular site. Backlinks are used for SEO purposes to optimize a website in a proper way. Backlinks are external links to your website. They show the transition from one site to another or from one page to another. They help to index your website’s pages correctly. SEO backlinks are an essential part of the search engine optimization process. They help search bots to crawl your site and rank it correctly to its content. Each backlink is a part of a ranking puzzle. That’s why every website owner wants to get as much as possible backlinks due to improving website’s SEO ranking factors. It’s a type o...

Electric systems

All fiber optic equipment will need electricity where they are located. The electricity must be of high quality, must have protections against surges and spikes and, generally, must have a reserve capacity to prevent the loss of communications during a power outage. Data equipment requires a separate ground connection and adequate power supply for air conditioning throughout the year. Attention should be paid to refrigeration to reduce energy consumption. Consult with the owner of the place, the client and the relevant personnel to plan the electrical installation.  Grounding and equipotential connection All cables and conductive components must be properly connected to the ground. Earth connections must be designed in accordance with the National Electricity Code (NEC) or other applicable codes or standards. Although most fiber optic cables are not conductive, any metal hardware used in fiber optic cabling systems (such as wall terminal boxes, racks, and connection panels) mu...
