OFC Technology Wing is an exclusive Optical Fiber Cable Technology solution provider, consisting of young & dynamic
entrepreneurs having experience in the field of Fiber Optic Cabling, trenching, blowing, Splicing & Testing, etc. Various
activities involved in this operation are as under:
- Open Trenching (excavation of earth) from 1 to 1.6 meters depth.
- HDD trenching (Horizontal Directional Drilling process).
- Laying of the duct – as per the specific requirement of the client.
- Duct Proving – to ensure no blockage in the duct.
- Testing of the OFC kept in drums – Pre-installation test.
- Blowing of the Optical Fiber Cable into the duct by using Air Compressors.
- Splicing/termination of the OFC at nominated junctions and in Sub-Stations as per the specification of the client.
- Splicing & jointing of OPGW (Optical Parallel Ground Wire), after stringing of the OFC in the Towers.
- Point to point testing of the joints with OTDR (Optical Time Domain Reflectometer).
- Final Link Test to establish the connectivity from one end to the other end of a particular stretch.
- Generation of various Test Reports.
We provide excellent service for duct laying – both by
open trenching (excavation of earth) and by HDD
(Horizontal Directional Drilling), without resorting to open
We have executed major works of trenching, duct-laying,
blowing of OFC & Splicing/terminations for clients like
Powergrid Corporation of India Ltd., in West Bengal (180
kms)and in Tamil Nadu (150 kms), Reliance East West
Pipeline at Hyderabad (250 kms) and also for Indian Oil
Corporation (Chennai-Trichy Pipeline project – 350 kms),
apart from providing similar services for different Telecom
firms in India.
We own the Plant & Machinery required for the above
work in India and we can mobilize them for similar work at
Oman.. Qualified & competent resources are available
on our rolls for carrying out trenching of all kinds.
Splicing (Jointing of OFC) by Fusion method.
We are following the internationally acknowledged
splicing technology viz., Fusion Method, which is briefly
explained as under:-
"Splicing is used to permanently join two optical fibers
where no additional changes are expected to be made
to those fibers at that junction. In fusion splicing the two
fibers are literally welded or fused together with a Fusion
Splicing Machine. This makes for a strong joint that
exhibits very low loss and virtually no reflection." Once a
splice has been, it often needs to be measured to find out
the splice loss at that joint.
OPGW (Optical Parallel Ground Wire) Splicing
OPGW cable is the short form of Optical Fiber Composite
Overhead Ground Wire. OPGW cable is used for
installation on new power lines with double function of
ground wire and communication, especially for
installation on normal voltage and extra high voltage
There will be two ends of OPGW cable at the
Transmission Tower; these two ends are brought down
from the tower, splicing is down at both ends of the OPGW
in the joint box and fixed at the top level of the tower. Here
also it is the same fusion splicing method.
Continuity Test to ensure prescribed standards OTDR (Optical Time Domain Reflectometer)
An OTDR is a specialized test instrument for optical fiber.
It is a very useful tool in that it provides a representative
picture of the fiber and only requires access to one end of
the fiber. An OTDR is the best method of measuring the
loss of an individual splice. The industry recognizes that
the most accurate measurement of actual splice loss is
the average of a 2-way (bidirectional) OTDR test.
Light source & Optical Power Meter Test :
This is useful for checking the optical power in performing
link-loss testing or trouble-shooting.
Polarisation mode dispersion test (PMD):
The polarization mode dispersion is the basis property of
single mode fibers. It affects the magnitude of the
transmission rate. PMD results from the difference of
propagation speeds of the energy of a given wave length
which splits into two polarization access that at right angle
to each other.
Chromatic Dispersion Test (CD Test)
Chromatic dispersion occurs because light pulses made
up of different wave lengths, each traveling at different
wave lengths down the length of fiber. These different
propagation speed broaden the light pulse when it arrives
at the receiver, reducing the signal to noise ration and
increasing the bit error.
