Fibre Optic Cabling Components & Installation Review Questions with complete Solutions Rated A+

Multimode - Answers Optical fibre designed to carry multiple light rays or modes simultaneously, with
each mode at a slightly different reflective angle within the core.

Modal dispersion - Answers Phenomenon where modes disperse over longer lengths in multimode fibre
transmission, limiting its use to short distances.

Step index multimode fibre - Answers Type of multimode fibre with a profile where light propagates in a
zigzagging pathway, often associated with legacy installations.

Graded index fibre - Answers Multimode fibre with a core where the refractive index diminishes
gradually from the center towards the cladding, reducing modal dispersion.

Single mode fibre - Answers Optical fibre with a small core designed to carry a single ray of light, offering
higher bandwidth than multimode fibres.

Core diameter rule for single mode fibre - Answers For a fibre to work as single mode, its core diameter
must be less than 10 times the wavelength being used.

Chromatic dispersion (CD) - Answers Caused by the fact that singlemode glass fibres transmit light of
different wavelengths at slightly different speeds, limiting the length light can be transmitted.

Transmitter - Answers Component that converts electrical input into optical signals for transmission
through the fibre.

Optical fibre - Answers Component used to guide light from the transmitter to the receiver in a fibre
optic installation.

Receiver - Answers Component that converts light pulses back into an electrical signal in a fibre optic
system.

Cable - Answers Component that carries the optical fibre link, installed internally within buildings or
externally with moisture barriers for protection.

Connectors - Answers Components used at each end of the fibre optic link to perfectly align the fibres
with devices, typically achieved using connectors.

Splices - Answers Permanent connections made at certain points in the fibre optic cable where sections
need to be joined, held securely within splice bridges.

Loose tube fibre - Answers Type of outdoor cable that can be used internally or externally, usually gel-
filled and containing multiple primary coated optical fibres.

Multi loose tube fibre - Answers Outdoor cable design where tubes with multiple fibres are stranded
around a central strength member, often with additional protection for outdoor applications.
