Sample Punjab PSEB Sr. Sec. NSQF Telecom (Optical Fibre Technician) Practice Questions

Try these sample questions to review concepts for the Punjab PSEB Sr. Sec. NSQF Telecom (Optical Fibre Technician) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1For long-haul telecom backbone links, which fibre type is the Optical Fibre Technician’s usual default choice?
A.Single-mode fibre (typically ~9 µm core)
B.Plastic multimode only
C.Unshielded twisted pair copper
D.Coaxial RG-6 only
Explanation: Single-mode fibre with a small core supports one primary propagation mode and is standard for long-haul and metro telecom backbones because of lower modal dispersion and longer reach at 1310/1550 nm.
2Compared with single-mode fibre, multimode fibre is typically preferred when the technician needs:
A.Transoceanic submarine spans only
B.Very short campus or building links with cheaper LED/VCSEL sources
C.Zero connectors at every joint
D.Replacement of all splicing with soldering
Explanation: Multimode’s larger core (e.g., 50/62.5 µm) eases coupling for short building/campus links and often uses lower-cost multimode sources; single-mode still dominates long-haul telecom.
3In a standard glass optical fibre, total internal reflection guiding works because the cladding has:
A.A much higher refractive index than the core
B.Zero refractive index
C.A slightly lower refractive index than the core
D.The same refractive index as air only
Explanation: Light is guided when the cladding refractive index is slightly lower than the core’s, enabling total internal reflection at the core–cladding boundary.
4Armoured outdoor OFC is chosen primarily to improve resistance against:
A.All need for splicing forever
B.Chromatic dispersion completely
C.The need for any jacket
D.Rodent bite, crush, and harsh outdoor mechanical damage
Explanation: Armour (e.g., steel tape/wire) adds mechanical protection against crush, rodents, and rough outdoor handling; optical performance still depends on fibre type and installation quality.
5A loose-tube outdoor cable construction is often preferred over tight-buffered indoor cable for duct routes because it:
A.Better protects fibres from outdoor moisture and temperature-related stress
B.Cannot be pulled into ducts at all
C.Requires copper pairs inside every tube
D.Is used only for patch cords under 1 m
Explanation: Loose-tube designs give fibres room to move and often include gel or dry water-blocking, improving outdoor/duct environmental protection versus typical tight-buffered indoor cables.
6Which statement best distinguishes aerial self-supporting OFC plant from indoor riser cable?
A.Indoor riser is always armoured steel; aerial never needs messenger support concepts
B.Aerial designs handle outdoor weather, UV, and ice/wind loading; indoor riser focuses on flame/smoke ratings and building pathways
C.Aerial cable uses only plastic multimode; indoor uses only single-mode
D.They are identical constructions with different colour ink only
Explanation: Aerial outdoor cables are engineered for weather and mechanical loading (sometimes ADSS or lashed to messenger). Indoor riser/plenum products emphasise fire-safety ratings and building pathway rules.
7The aramid (e.g., Kevlar) yarns in an optical cable primarily provide:
A.The optical guiding path for light
B.Electrical power feed to the laser
C.Tensile strength during pulling and handling
D.Automatic OTDR calibration
Explanation: Strength members such as aramid yarns take tensile load so the glass fibre is not stretched during pull-in and handling.
8An Optical Fibre Technician selecting plant for a high-capacity long-distance DWDM route should prioritise:
A.Category-6 UTP only
B.Multimode OM1 exclusively
C.Unterminated copper drop wire
D.Low-loss single-mode fibre suitable for 1310/1550 nm telecom windows
Explanation: DWDM long-haul systems run on low-loss single-mode fibre in the telecom wavelength windows (notably around 1550 nm with 1310 also used in many designs).
9Ribbon fibre cable is especially useful when the technician must:
A.Mass-fuse many fibres efficiently in high fibre-count plant
B.Avoid all documentation
C.Use only mechanical splices forever
D.Eliminate bend-radius limits
Explanation: Ribbon constructions group fibres in flat arrays so mass fusion splicing can join many fibres in one operation—valuable in high fibre-count routes.
10Microbend or macrobend sensitivity matters to the technician because tight bends can:
A.Convert fibre into copper automatically
B.Increase optical loss and degrade link performance
C.Increase refractive index of air only
D.Remove the need for connectors
Explanation: Bending beyond design limits causes light to leak from the core (macrobend/microbend loss), raising attenuation and risking service failure.

About the Punjab PSEB Sr. Sec. NSQF Telecom (Optical Fibre Technician) Exam

Punjab PSEB Senior Secondary NSQF Telecom is the Class 12 National Skill Qualification Framework trade (code 222) for the job role Optical Fibre Technician (Optical Fiber Technician).

Official assessment is Theory 40 + Practical 50 + INA 10 = 100. Pass requires at least 33% separately in Theory, Practical, and INA, and 33% aggregate per the Scheme of Studies. Fees and exact blueprints are notified by PSEB on pseb.ac.in. The 100 questions on this page are a free English-language multiple-choice study adaptation for theory concepts only; they are not a substitute for official practicals, viva, or skill certification. This bank is intentionally distinct from PSEB Matric NSQF Telecom (code 97) Optical Fiber Splicer.

Punjab PSEB Sr. Sec. NSQF Telecom (Optical Fibre Technician): Suggested Study Strategy

1Pair every MCQ category with school practical demonstrations — theory recall without supervised skill practice is incomplete for NSQF Telecom.
2Learn fibre type first (single-mode vs multimode, indoor vs outdoor/armoured) — many technician questions start with selecting the right plant for the route.
3Drill the fixed splice sequence: strip → clean → cleave → align → fuse/mechanical join → protection sleeve, then document splice loss.
4Contrast OTDR (locate events along a fibre) vs power meter + light source (end-to-end power/loss) vs VFL (visible short-range faults).
5Never look into a live fibre or laser port; treat glass shards as hazardous waste—use safety glasses and dispose of scraps in a sealed container.
6Do not neglect practical and INA marks — they are 60 of 100 under the official Theory 40 + Practical 50 + INA 10 scheme.
7Keep this bank distinct from Matric Optical Fiber Splicer revision: focus on technician-level OTDR diagnosis, connectors, fault localization, and documentation language.
