This presentation discusses optical fiber cables and accessories. It describes optical fiber as thin glass fibers that transmit light pulses to carry information over long distances. It then discusses the history of optical fibers and their structure. The presentation covers the types of optical fiber cables including single mode, multi mode, armored, underground, aerial, duct and indoor cables. It also discusses optical fiber cable enclosures and optical distribution frames, what they are used for, and common types. The presentation concludes that optical fibers are rapidly replacing copper wires due to their advantages for high speed data transmission.

4. What is Optical Fiber?
 A hair thin cylindrical fiber of glass or any
transparent dielectric medium
 Uses light pulses to transmit information
down fiber lines.
 Its function is to guide visible and infrared
lights over long distances.

5. History
 The term fiber optics was coined by Indian
physicist Narinder Singh Kapany.
 Fiber optics was first demonstrated by Daniel
Colladon and Jacques Babinet in Paris in the early
1840s.
 The first working fiber-optical data transmission
system was demonstrated by German
physicist Manfred Börner at Telefunken Research Labs
in Ulm in 1965.
 NASA used fiber optics in the television cameras that
were sent to the moon.

15. Optical Fiber Cable (OFC) Enclosure

16. OFC Enclosure
 A device to hold the fiber cables to access
the network.
 Accessible for housing for optical fiber
services
 Plays an important role in sealing,
protection, installation of fiber connector
head and storage.

17. Uses
 Protect terminations from damage
 For safety and well-managed
environment of fiber optic splices.
 For efficient management and
storage of the spliced fiber optic
cables.

18. Types
Fiber dome enclosure
Fiber inline enclosure

19. Fiber guard enclosure
Optical terminal enclosure

20. Optical Distribution Frame (ODF)

21. Optical Distribution Frame
 A frame that is used to provide cable
interconnections between communication
facilities.
 Integrate fiber splicing, fiber termination, fiber
optic adapter and connectors and cable
connections together in single unit.
 12, 24, 48,72, 96, 144, 576 fiber counts type of
ODF available.
 Protects fiber optic connections from damage.

22. Uses
 To organize the fiber optic cable
connections.
 Used in live cables.
 Useful device in fiber optic cable
management.
 Used in long haul and local network relay
transmission of optical fibers

23. Types
Wall mount ODF
 Only accepts small
fiber counts because
the space is restrained.
 Suitable for fiber
distribution with small
counts.

24. Floor mount ODF
• Has a fixed and
large fiber
capacity in
closed structure.
• Consists of box
and distribution
board.
• Designed with
fixed fiber
capacity and nice
appearance

25. Rack mount ODF
 Installed on the
rack according to
fiber optic cable
counts and
specifications.
 Can be installed on
to the commonly
used transmission
rack.

26. Conclusion
 Optical fibers are rapidly used in today’s
technological world.
 Optical cables are superior than the copper
wires
 The OFC enclosure is a popular fiber optic
protector of fiber optic network during both
deployment and maintenance.
 Hence, OFCs has been growing day to day and
is expected to grow more in further years.
