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.
