1In an optical fibre, which part carries the light signal from one end to the other?
A.Core
B.Jacket only
C.Strength member only
D.Outer armour only
Explanation: The core is the innermost glass (or plastic) path through which light propagates. Cladding keeps light in the core; jacket and strength members protect the fibre mechanically.
2What is the main function of the cladding around an optical fibre core?
A.Reflect light back into the core using a lower refractive index
B.Carry electrical current alongside the light
C.Replace the need for a jacket
D.Act as the primary tensile strength member
Explanation: Cladding has a slightly lower refractive index than the core so light undergoes total internal reflection and stays guided in the core.
3Light stays inside an optical fibre primarily because of which principle?
A.Total internal reflection (TIR)
B.Magnetic induction
C.Electrical conductivity of glass
D.Gravitational lensing
Explanation: When light in the higher-index core hits the cladding interface above the critical angle, it is totally internally reflected and guided along the fibre.
4Compared with multimode fibre, single-mode fibre typically has:
A.A smaller core and lower modal dispersion for long-haul links
B.A much larger core for more modes
C.Higher attenuation over long distances by design
D.No need for careful alignment when splicing
Explanation: Single-mode fibre has a small core (about 8–9 µm) supporting one principal mode, which reduces modal dispersion and suits long-distance, high-bandwidth links.
5A typical single-mode fibre core diameter is closest to:
A.8–9 micrometres (µm)
B.2 millimetres
C.125 millimetres
D.1 centimetre
Explanation: Standard single-mode telecom fibre has a core of roughly 8–9 µm and cladding of about 125 µm.
6Which statement best describes attenuation in optical fibre?
A.Reduction of optical power as light travels through the fibre
B.Increase of signal speed with distance
C.Conversion of light into electricity inside the core
D.A method of joining two fibres
Explanation: Attenuation is the loss of optical power with distance (scattering, absorption, bends). It is measured in dB or dB/km.
7Why is route inspection important before OFC installation?
A.It identifies obstacles, hazards, bend constraints, and a feasible cable path
B.It permanently splices all fibres on paper only
C.It eliminates the need for any permissions
D.It replaces OTDR testing after installation
Explanation: A route survey/site walk finds poles, pipes, manholes, soil conditions, access points, and hazards so trenching, ducting, or aerial work can be planned safely and correctly.
8In basic optical fibre communication, the three main sections of a simple link are:
A.Transmitter, optical fibre cable, and receiver
B.Battery, antenna, and speaker only
C.Switch, router, and Wi-Fi only
D.Transformer, bus bar, and meter only
Explanation: A basic OFC link converts the signal at a transmitter, guides light through fibre, and recovers it at a receiver (photodetector).
9Aramid yarn (Kevlar) in an optical fibre cable is primarily used as:
A.A strength member to resist tensile stress
B.The light-guiding core
C.A conductive earth wire
D.A laser source
Explanation: Strength members such as aramid (Kevlar) yarn protect the glass fibre from stretching under pull tension during installation.
10Multimode fibre is generally preferred for which scenario?
A.Shorter campus or building links where many modes can be tolerated
B.Transoceanic submarine long-haul only
C.Replacing all single-mode long-haul backbones
D.Situations that require zero connectors ever
Explanation: Multimode’s larger core eases coupling for shorter distances (buildings/campuses) but has more modal dispersion, so single-mode dominates long-haul.
