How To Install and Test the Fiber Optic Cables

Share

In the telecommunications industry today, how to install the fiber optics that each optical engineer must learn in their work. Don’t froget, when you install the fiber optics, you must testing your fiber optic system. Optical-fiber testing is one of the final and most important procedures in installing optical networks.

How to install the fiber optic cable?

Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. Indoor cables can be installed in raceways, cable trays,placed in hangers, pulled into conduit or innerduct or blown though special ducts with compressed gas. The installation process will depend on the nature of the installation and the type of cable being used. Installation methods for both wire and optical fiber communications cables are similar. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress may harm the fibers, potentially causing eventual failure.

The install fiber optic cable tips:

a) Follow the cable manufacturer’s recommendations. Fiber optic cable is often custom-designed for the installation and the manufacturer may have specific instructions on its installation.
b) Check the cable length to make sure the cable being pulled is long enough for the run to prevent having to splice fiber and provide special protection for the splices.
c) Try to complete the installation in one pull. Prior to any installation, assess the route carefully to determine the methods of installation and obstacles likely to be encountered.

Testing fiber optic cables steps:

After installation, test each fiber in all fiber optic cables for verification of proper installation. Perform the following tests:
a) Continuity testing to determine that the fiber routing and/or polarization is correct and documentation is proper.
b) End-to-end insertion loss using an OLTS power meter and source. Test multimode cables by using TIA/EIA 526-14 Method B, and single-mode cables using TIA/EIA 526-7 (single-mode). Total loss shall be less than the calculated maximum loss for the cable based on appropriate standards or customer specifications.
c) Optional OTDR testing may be used to verify cable installation and splice performance. However, OTDR testing shall not be used to determine cable loss.
d) If the design documentation does not include cable plant length, and this is not recorded during installation, test the length of the fiber using the length feature available on an OTDR, or some OLTSs.
e) If testing shows variances from expected losses troubleshoot the problems and correct them.

Various Advantages Of Fiber Optic Cables

Share

Communication industry has been stormed by the advent of fiber optic cable. The main advantages offered by these cables include a wider bandwidth, light weight, small size and in any case has more flexibility. In addition to it, the core reason behind its popularity is that advanced technology used by these cables. As we know the fiber optic cable, the fiber optic cable is a cable containing one or more optical fibers. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. For example, the 10g fiber cable is has plastic layers and contained in a protective tube, we can offer different jacket color and any length are available for these cables .

In fact, the whole fiber optic technology makes use of fiber optics. The typical fibers today are made out of glass or plastic since it is possible to make them thin and long. Also both glass and plastic are transparent at particular wavelengths, which allow the fiber to guide light efficiently. These optical fibers are thin, ultra-flexible and transparent and transmit the light between two ends of the fiber quality as compared to copper wire. So, with their superior technology these are more appropriate for smooth communication between far distances. In addition to it, the usage of these cables results in much less loss of signals which means uninterrupted and smooth communication. More than 80% of the distance data traffic through the intelligent use of these fiber optic technology is transferred.

Other advantages of fiber optic cables include it is inexpensive and suits properly to extremely thin diameters in the range between 0.8mm to 40mm. Will be extremely thin, a number of fibers run together along many connections in the same cable. It provides a clearer telephone lines and TV reception, as the light signals that are in the same cable does not interfere with each other to function. This ultimately leads to less loss of signal. These cables can also be called as the safer ones because no electricity passes through these cables and hence there will not be any fire issues.

In comparison with other lines such as copper wires, these cables are definitely the superior ones because they are lightweight and small sized. With the above advantages, it is obvious why fiber optic cables that are used in many telecommunications and computer networks. These cables are the most trusted and best replacement of copper cables.

Relationship Between The Fiber Optics And Fiber Optic Cable

Fiber Optic Cable:

In fiber optic cable, optical fibers carry digital data signals in the form of modulated pulses of light. This is a relatively safe way to send data because no electrical impulses are carried over the fiber optic cable. This means that fiber-optic cable cannot be tapped and the data stolen, which is possible with any copper-based cable carrying data in the form of electronic signals.

Fiber optic cable is good for very high-speed, high-capacity data transmission because of the lack of attenuation and the purity of the signal.

A fiber optic cable can transmit information at very high speed over a very great distance. It comprises one or more optical fibers enveloped in a thermoplastic sheath for mechanical protection.

Fiber Optic Composition:

Optical fibers consist of an extremely thin cylinder of glass, called the core, surrounded by a concentric layer of glass, known as the cladding. The fibers are sometimes made of plastic. Plastic is easier to install, but cannot carry the light pulses as far as glass.

Each glass strand passes signals in only one direction. So a cable consists of two strands in separate jackets. One strand transmits and one receives. A reinforcing layer of plastic surrounds each glass strand while kevlar fibers provide strength.

Fiber Optic Technologies

Data transmission via fiber optic cable uses a laser beam, offering very little loss over great distances. The core fiber has a higher refractive index than its cladding material, keeping the light within by avoiding multiple reflection (single-mode fiber), thus acting as a wave guide.

Fiber Optic Cable Types:

Now,many fiber optic cable suppliers provide a wide range of quality optical fiber cables with detailed fiber optic cable specifications displayed for your convenience selecting.Many types of fiber optic cable including about 250um bare fiber,tight buffer,large core glass,simplex fiber optic cable,duplex fiber cable,OM3 OM4, Indoor Outdoor cable,loose tube,breakout cable,ribbon cable,LSZH cable,armored cable,ftth cable,figure 8 aerial cable,plastic cable,hybrid and composite cable,adss cable,special cable and so on.

How to Choose Fiber Optic Cable?

Fiber optic cables are preferable to electrical cables over long transmission distances or when an electromagnetic disturbance in an industrial setting might interfere with the signal. Single-mode fibers are required for high-speed, long-distance transmission, while multi-mode fibers are suitable for low speeds and short distances.

Optical fibers have found a widespread use in optical technologies. Today is electronical high-tech applications as for example the Laser Scanning Microscopy, the sensor technology, machine vision, medical laser or military technology use flexible elements in form of optical fibers for light transfer frequently. In most cases, very special requirements to design and function of optical fiber cables are put. We realize custom-made solutions regarding the design of fiber connectors and wavelength, transceiver sale mode behavior, polarization and beam profile.This enables short decisions and high flexibility in the creation of single components as well as system solutions.
