Information and Communication Technology (ICT) and Indian

Railways • ICT is known to have made

– immense impact in booking of railway tickets

– can make an impact in

• service management

• tracking movement of goods

• control of wagons

• passenger amenities– can improve decision making and management

Passenger Services

• Voice communications– GSM is the best solution

– Railways can work out a deal with Cell operators, or RAILTEL can float a Cellular Operator company

• Data Communication– GPRS or corDECT can provide data communication to moving train

• provide a Internet kiosk on a train

• provide 802.11 wireless connection in the train for passengers using laptops

– 802.11 wireless connection also at stations for passengers to download and upload when train stops (at low cost)

• fibre provides backbone

OPTIC FIBRE CABLE

What is OFC ?Fibre Optic cable functions as a

“LIGHT GUIDE”, guiding the light

introduced at one end of the cable

through to the other end.

Advantages of Optic Fibre• More Bandwidth - Thousands of Channels

• Low Loss - 0.5db per km

• Less number of Repeaters

• Electro Magnetic Immunity

• Small size & Light Weight - Easy to handle

• Greater Safety - No Electric Hazards

• Higher Security

OFC Applications•Telecommunication Network

•Junction Network & Long Distance Network

•Submarine cable

•High EMI areas

•Explosive environment

•Computer links & Local Area Network

•Cable television

•Medical Field , Automobile Field

TIR is achieved since Core and Cladding having different Refractive Indices.

Core RI – 1.48

Cladding RI – 1.47

Principle of Working

Total Internal reflection

•Centre Strengthening Member – GRP, FRP

•Loose Tube Buffers – 2.4 mm Dia

• Fibres are placed inside the Buffers along with

Jelly to prevent moisture entry.

•Primary Strength Member – Aramid Yarn -Kevlar

•Inner Sheath – Black

•Outer Nylon Sheath - Orange

Construction of Cable

Propagation of Light inside the Fibre

OFC types

•Single Mode Fibre

•Multi Mode Fibre

•Plastic Optic Fibre

•A much smaller core Diameter

•The Core dia is 8 to 10 Micrometer

•Cladding Dia is 125 Micrometer

•Very large bandwidth

•Light can go for very long distances

Single Mode Fibre

Has a large Core Diameter Core Diameter - 50, 62.5, 100 Micro meter

Cladding dia - 125 Micro meter

Light waves are dispersed into number of paths

Multiple path of light cause signal distortion

Suitable for shorter length like LAN

Multimode

Plastic Optic Fibre

•Large Core - 1 MM Dia

•Multimode Fibre

•Used in Automobile Industry instead of Copper

•MOST (Media Orientated System of transport )

Method of cable Splicing

• STRIPPING• CLEAVING• FUSION PROCESS

Stripping • Strip back the external sheathing of the

cable using a rotary stripping tool. Cut back the aramid strength member using ceramic or kevlar scissors.

• Strip the primary buffer from the fiber using fiber strippers not ordinary wire strippers. Do this a small section at a time to prevent the fiber breaking, about 10mm (3/8 in) on each cut is fine until you get used to it. Strip back about 35mm (1.5 in).

•Clean the bare fiber with a lint free wipe and isopropyl alcohol, it will "squeak" when it is clean.

Cleaving • The cleaver first scores the fiber and

then pulls the fiber apart to make a clean break. It is important that the the ends are smooth and perpendicular to get a good joint, this is why a hand held cleaver will not do.

• Basically the operation consists of putting the fiber into the groove and clamping, then close the lid and press the lever

The Fusion Process

• Once the fiber ends are prepared they are placed in the fusion splicer. Press the button and the machine takes care of the rest of the fusion process automatically

• First the two fibers are aligned, you can see this on the photo where a much magnified image shows the two fiber ends. The display also shows how well the cleaver does its job of producing a perfect 90 degree cut.
