Fiber Optic Cable Installation and Handling
Instructions
2
Introduction

• Fiber optic cables can be easily damaged if they
  are improperly handled or installed. It is
  imperative that certain procedures be followed in
  the handling of these cables to avoid damage
  and/or limiting their usefulness.
• Do not exceed maximum cable lengths.
• Do not exceed minimum bend radius for a given
  cable type.

Overview

• Avoid twisting cable Optical fibers require
  special care during installation to ensure
  reliable operation. Installation guidelines
  regarding minimum bend radius, tensile loads,
  twisting, squeezing, or pinching of cable must be
  followed. Cable connectors should be protected
  from contamination and scratching at all times.
  The following are a few general comments to
  consider when installing fiber optic cables are
• Make sure you check the installation instructions
  of the module for the appropriate cable lengths
  to ensure proper operation.
• You may experience additional attenuation loss
  when using bulkhead connectors to join cables
  even when the total length is less than the
  maximum.

Fiber Optic Cable Pulling Techniques

• On runs from 40m to 100m, use proper lubricants
  and make sure they are compatible with the cable
  jacket.On runs over 100m, use proper lubricants
  and pull from the middle out to both ends.
  Installation methods for both wire cables and
  optical fiber cables are similar. Just remember
  these rules
• Never pull on the connector
• Use a pulling grip 
• Monitor tension
• Always use a straight pull
• For a 40m or longer pull
• Use a swivel-pulling eye

5
Routing Fiber Optic Cables

• Take care to properly route cables through
  cabinets and right angle raceways.
• Install cables in raceways without loops.
• Protect cables from excessive or frequent
  bending. 
• Use proper cable pulling techniques when routing
  cables. 
• Attach cables with plastic clamps having large
  surface areas.

Cleaning Techniques for Fiber Optic Cables

• Cleaning Fiber Optic Transceivers
• Fiber-Optic Specifications

Cleaning Fiber Optic Transceivers

• Proper cleaning of the fiber optic cable ends and
  transceivers is essential to minimize system
  attenuation. Dirty fiber optic cables cross
  contaminate their mating transceivers. Conversely
  a dirty transceiver contaminates its mating fiber
  optic cable. There are a variety of ways to clean
  fiber optic components.
• Always choose an optical grade cleaner for these
  purposes.
• Use a wet wipe to loosen particles on the end of
  the cable connector using a circular or straight
  wiping motion while using care to avoid wiping
  over area of pad that has already been used.
• Do not use a back and forth scrubbing action.
• Always use a clean area of the swab for each
  connector.
• When in doubt use a fresh wipe.
• Follow up the wet wipe cleaning with a dry wipe
  to remove any residue.
• Use canned air to remove any lint from the cable
  end.

Fiber-Optic Specifications

• What are the specifications of the fiber-optic
  cables Time-O-Matic ships with an LED sign?Watch
  fire Signs has used dual fiber-optic cables since
  June of 2005. Specifications on the dual
  fiber are as follows
• Plenum rated. Approved to be placed in plenum
  spaces of buildings. OFNP listed.
• Standard ST connectors
• Diameter - 62.5 microns
• Multi-mode
• Wavelength, for serial communications (Fiber Com
  box, CB) 820nm, For Ethernet over Fiber 1310nm
• Minimum Bend Radii 2.0" operation, 3.0" bend
  radius installation
• Pull Strength - 303 lbs. during installation 90
  lbs. during operation
• Entire Cable Diameter - 0.19"
• Glass core

Installation Standards

• The fiber-optic cable should be installed in 1
  1/2" or larger PVC or EMT conduit.
• The fiber-optic cable must be placed in
  weatherproof conduit for its entire life-span.
  Exposure to sunlight will bleach the fiber and
  cause loss of communication.
• Use caution when pulling the fiber through conduit
  containing large power wires. 
• Cleaning ST connectors Use alcohol and a lint
  free cloth to clean the ST connectors. Do not
  leave fingerprints on the glass fiber.
• Do not remove the pulling eye prior to installing
  fiber this could cause damage to the fiber and
  connectors.
• Do not fold or kink the fiber, this can cause the
  fiber to break.
