A1. Linear bus, ring, star, and tree topologies.
A4. The process of varying one or more characteristics of an optical
signal to encode and convey information.
A5. A discontinuous signal that changes from one state to another in
A6. Binary 1.
A7. If long strings of 1s or 0s are present causing a lack of level
A8. A half-period optical pulse present in the first half of the bit
A9. Binary 0.
A10. A continuous signal that varies in a direct proportion to the
instantaneous value of a physical variable.
A11. Intensity modulation.
A12. Because cost can be minimized and complex multiplexing and timing
equipment is unnecessary.
A13. Because fiber optic systems that incorporate complex architectures
can be simplified into a collection of point-to-point data links before
beginning the design process.
A14. Launch power, connection losses, bandwidth, cost, and reliability.
A15. Power budget and risetime budget.
A16. Minimum bend radius.
Never bend an optical fiber or cable at a radius of curvature less
than the minimum bend radius.
Never pull fiber optic cables tight or fasten them over or through
sharp corners or cutting edges.
Always clean fiber optic connectors before mating.
Do not kink or crush fiber optic cable during installation of the
Allow only trained, authorized personnel to install
or repair fiber optic systems.
