Fiber Cable Handlingoptical fiber c ables are sensitive to d amage during handling & installat ion. Some of theImportant parameters that need special attention during cable installation are:

Important parameters that need special attention during cable installation are:

Bending radius & tensile strength. The cable should never be bent below minimumBending radius atAny location. Do ing so can result in b ending losses and /or breaks in the Generally the bending

radius o f a cable is greater than 20D, where D is the d iameter of c able

Laser Precaution

Laser beam used in optical communication is invisible and can seriously damage theEyes. Viewing it directly does not cause any pain and the iris of Eye does not closeautomatically as it does while viewing the br ight light. T his can cause serious damageto the retina of eye. Therefore,

Never look into a fiber having a laser coupled to it. If eye is accidentally exposed to LASER beam, immediately rush for medical assistance

Optical Fiber Handling PrecautionThe broken ends of fibers creat ed during termination a nd splicing can be dangerous

The ends are extremely sharp and can easily penetrate the skin. They invariably breakOff and are very hard to find and remove. Sometimes pair of tweezers and magnifyingglass are needed to take them out. And any delay in taking the fiber o ut of body could lead toInfection, which is dangerous. Hence

Be careful while handling the fibers.

Do not stick the broken ends of fiber into your fingers

Do not drop fiber pieces on the floor where they will stick in carpets or shoes and be Carried elsewhere-like home

Dispose off all scraps properly

Do not eat or drink near the installation area

Material Safety

Fiber optic splicing and termination processes require various chemical cleaners andAdhesives. The safety instructions defined for these substances should also beFollowed. If there is confusion in usage of these products, ask t he manufacturer for aMSDS (Material Safety Data Sheet). R emember the following instructions while working with materials

Always work in well-ventilated areas.

Skin contact to materials involved as much as possible

Avoid using chemicals that cause allergic reactions

Even simple isopropyl alcohol, used as a cleaner, is flammable and should beHandled carefullyFire SafetyThe fusion splices use an electric sp ark to make splice, so ens ure that thereAre no flammable gases in the space where fusion splicing is done? Splicing should never be

Done in places manholes where gases can accumulate the cables are brought up to the surfaceInto a splicing trailer where all fiber works is done. So the splicing trailer is temperature -controlled

And kept spotlessly clean to ensure good splicing.

Smoking should not be allowed around fiber optic work. T he ashes from smoking cancontribute to the dust problems in fibers, apart from the danger of explos ion posed byThem due to presence of combustible substances

Manhole /Underground vaults safety:

Safety during Duct Installation

Explosive gase s or vapors might b e present in manholes due to leaking of nearby gas or

Liquid pipelines. Befo re entering any manho le test the manhole atmosphere e with an approved

Test kit for flammable and poisonous gases Avoid usage of any device that produces spark or flame in manhole

To minimize the risks of an accident in the work area follow specified rules for setting up barricades, manhole guardsAnd warning signs.

Before pulling cable directly from figure 8 shapes, make sure that the area inside the loop of the cable is clear of

Personnel and equipment. Failure to do so may result in injury to personnel or damage to the cable due to entanglement.

Ensure that the tools and equip ments used for cable installat ion are in proper condition.

Corrosion of equipments may damage cable or cause injury to personnel Take care of electrichazards, if electrical lines ar e passing t hrough the manho les or vaults where installatio n is being done.

Safety during Aerial cable InstallationBefore climbing a pole, inspect it for various safety issues as splintering, insect nests, sharp protrusions

Use leather gloves when climbing or getting down on pole and when workingWith sharpInstruments or materialsWear rubber gloves when working near expos ed electrical circuits to avoid electric shock Follow electrical safety

Rules when working near power lines.

Personal normally should stay away from the area where a cable is being pulled around a piece of stationary hardware

Under tension. Appropriate safety measures should be taken while working near the installation site.

Keep hands free from tools when climbing or getting down on pole or ladder

Suitable accessories must be used during installation to ensure smooth and safe working. Only essential skilled personnel should stay near the installation site during tensioningOperation can minimize risk ofInjury or death. Nobody should allow climbing onIntermediate poles, while tensioning. Passerby on ground should beKept away fromPoles during tensioning. Suitable warning / Safety display board should be put onInstallation site.

Ground every metallic components to avoid electric hazards due to spark

Produced by power lines or any other means

Keep all food and beverages out of the work area. If fiber particles are ingested they can cause internal hemorrhaging.

Wear disposable aprons to minimize fiber par ticles on your clothing. Fiber particles on your clothing can later get into food,

Drinks, and/or be ingested by other means. Always wear safety glasses with side shields, suitable safety Helmet, Safety belts

And protective gloves. Handle the fiber optic splinters similar to glass splinters .

Never look directly through the end of fiber cables till you ensure that there is no light source at the other end. Use a fiberOptic power meter to make sure thatFiber is dark. When using an optical tracer or continuity checker, look at the fiberfrom an angle at least 6 inches away from your eye to determine if the visible

Light is present. Only work in well-ventilated areas.

Do not touch your eyes while working with fiber optic systems until they have been thoroughly washed.Keep all combustible materials away from the curing ovens

Dispose the fiber scraps properly

Thoroughly clean your work area after completion of installation

Do not smoke while working with fiber optic system

Aerial Cable installation

Introduction

This manual provides general GUIDELINES for installation of ADSS cable on high voltage powerline. Actual installation process is influenced by local conditions, customers existing

procedur e & requirements. ADSS cable installation procedure is essentially same as

installatio n of conductor on tower .Safety is main concern for working near High voltagePower lines. Do not void any safety rules either given by NESC or your local regulation. UseConvenient way of installation as per the rules & regulations.

Complete installation of Aerial Cables typically involves the following processes:

Pre-Installation Route surveyHanging of cableTensioningTermination and ClampingData Recording

Installation Considerations:

Optical fiber cable installation over high voltage power line is influenced by many mechanical

Environmental & electrical paramet ers. Before installing cable over tower it is very importantto consider all these parameters in cable design & installation.

For safety & durability of cable plan installation as per data sheet given by cable manufacturer.

To fulfill installation objective following considerations should be incorporate in pre survey.Cable Handling

All optical fiber cables are sensitive to damage during handling & installation, such damageCan degrade cable performance to the extent that replacement is necess ary. In Order to avoidDamaging cable following precautions should be taken.

a. Cable Unloading

While unloading truck it is important that drum of cable not to be dropped on tiers of

Floor. The weight of Drum & cable may cause deflection of Drum flange resultingFlattening, deformation or damage of cable.

The Drum must be rolled from truck on t o receiving platform, which should be in same height as t he tailgate

of truck. An alternate is to use forklift to unload drums from truck.

If inclined r amps are used roll drums over it and dont allow Drums to roll o ut off control.

Roll each Drum away from the bottom of the r amp before handling the next Drum.

b. Cable Wrapping

Drum wrappers play an important role in protecting cable from damage. All Drums are wrapped by wooden laggings

to protect cable from damage by minor impacts resulting from Drum rolling on rough surfac e. Cable on Drumis wrapped by black po lythene gives thermal protection to cable.

Dont remove complete wrapping from Drum until cable is ready to install

c. Cable Storage

The drums should always be stored in an upright position. Storage of drums in an alter native position can lead toWinding defects

If storage plac e is limited and it becomes necess ary to stack. Stack completely

Wrapped Drums on their flanges edge

If wrapper is removed from drum, their rolling edge should be lined up in rows with the flanges touching eac h other

so that the flanges do not overlap with cable andaccidentally damage itOpen drums stored by touching flanges
