The right way to install and test the Fiber Optic Cables

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 have to testing your fiber optic system. Optical-fiber tests are one of the final and many important procedures in installing optical networks.

 

How to set up the fiber optic cable?

 

Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable might be direct buried, pulled or blown into conduit or interdict, or installed aerially between poles. Indoor cables could be installed in raceways, cable trays, put into hangers, pulled into conduit or interdict or blown though special ducts with compressed gas. Cellular phone process will depend on the nature of the installation and also the kind 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) Stick to the cable manufacturer's recommendations. Fiber optic cable is often custom-designed for that installation and the manufacturer might have specific instructions on its installation.

 

b) Check the cable length to make sure the cable being pulled is long enough for that go to prevent needing to splice fiber and provide special protection for the splices.

 

c) Attempt to complete the installation in a single pull. Just before any installation, assess the route carefully to look for the ways of installation and obstacles likely to be encountered.

 

Testing fiber optic cables steps:

 

After installation, test each fiber in most fiber optic cables for verification of proper installation. Carry out the following tests:

 

a) Continuity testing to find out that the fiber routing and/or polarization is correct and documentation is proper.

 

b) End-to-end insertion loss utilizing 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 under 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 accustomed to determine cable loss.

 

d) If the design documentation does not include cable plant length, which is not recorded during installation, test the length of the fiber using the length feature on an OTDR, or some OLTSs.

 

e) If testing shows variances from expected losses troubleshoot the issues and proper them.

Common Armored Fiber Optic Cables

  Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.   The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or bu

what the Differences Between FBT Splitter and PLC Splitter

  In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circuit splitter (PLC splitter). You may have one question: what’s the difference between them and shall we use FBT or PLC splitter?   What Is FBT Splitter? FBT splitter is based on a traditional technology to weld several fiber together from side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tu

Introduction of Optical Fiber Couplers and How Do They Work?

 What are optical fiber couplers? A fiber optic coupler can be defined as an optical component used with one or more input fibers and several output fibers in fiber optic systems. A coupler essentially puts two or more cores of fibers together to connect. The simple coupler is the fused fiber 2x2 coupler. Couplers are used as multiplexers that are resistant to certain wavelengths. A fiber output depends on the wavelength of light and the frequency of polarization. The fiber refractive index also plays a significant role in the performance. Let’s checkout how do optic couplers work to understand this better. How do fiber optic couplers work? Either fiber optic couplers separate optical signals into multiple paths or combine multiple signals in one direction. Optical signals are more complicated than electrical signals, making it more difficult to design optical couplers than their electrical copy. Unlike electrical currents, the optical signal consists of a stream of signal carriers, in
