Fiber Optic Cable Installations

What should you include in a fiber installation materials list?

• Cable, connectors/splices (2–5% extra), closures, trays, panels, ducts, restoration kit.

• Only cables and connectors are necessary.

• Trays and panels are optional, but closures are required.

• A restoration kit is not needed for fiber installations.

Which multimode fibers are laser-optimized?

• OM1 and OM2

• OM3 and OM4

• OM5 and OM6

• OM7 and OM8

What is a typical connector loss value?

• About 0.1 dB per mated pair.

• About 0.3 dB per mated pair.

• About 0.5 dB per mated pair.

• About 1.0 dB per mated pair.

What’s a hybrid indoor/outdoor cable?

• A type of cable used exclusively for outdoor installations.

• A dual-jacketed cable suitable for transition from OSP to premises.

• A single jacket cable designed for indoor use only.

• A cable that can only be used in hybrid vehicles.

What are the main types of outside plant (OSP) cable installations?

• Underground (in conduit)

• Direct Buried

• Microtrenching

• Aerial

• Underwater/Submarine

What formula determines the system power budget?

• Transmit Power + Receiver Sensitivity

• Transmit Power – Receiver Sensitivity

• Transmit Power / Receiver Sensitivity

• Transmit Power × Receiver Sensitivity

What device holds and protects fiber splices?

• Splice tray

• Fiber enclosure

• Cable connector

• Optical splitter

What is microtrenching used for?

• Installing microducts for air-blown fiber, often in FTTH applications.

• Creating drainage systems for urban areas.

• Laying traditional copper cables for telecommunication.

• Installing solar panels in residential areas.

What is the loss budget used for in fiber design?

• To ensure the total link loss is within the system’s power budget.

• To calculate the maximum distance of fiber optic cables.

• To determine the type of connectors to be used.

• To estimate the cost of fiber installation.

What is the most common singlemode fiber type used in OSP?

• G.652 (standard SMF optimized for 1310 nm)

• G.655 (non-zero dispersion-shifted fiber)

• G.657 (bend-insensitive singlemode fiber)

• G.654 (submarine fiber)
