& CORRECT DETAILED ANSWERS|| GRADEDA+
1. Code: Addresses the safety of persons, property and the environment associated
with the ITS cabling Installation
2. NEC: National electric code
3. Frequency conversion chart: One thousand hertz = 1KHz
One million Kilohertz = 1 MHz
One billion Megahertz = 1 GHz
4. NFPA: National Fire protection association
5. AHJ: Authorities having jurisdiction
6. TIA/EIA: - Telecommunications Industry association
- Electronic industries alliance
7. BICSI: - Building
- Industry
- Consulting
- Service
- International
8. Frequency: Optical pulses using cycles per second, 1 unit of hertz = 1 cycle per
second
4hz = 4 cycles per second
9. Definition of transmission: The movement of information in the form of electrical
or optical signals from one point to another through a transport medium
10. Refraction: Bending of the light as it passes from one medium into another
11. MHz: - Quantifies the bandwidth of a cabling system in a frequency range
- Information handling capabilities of the medium
12. Megabits: - transmission rate
- Number of bits information that can be transported over the medium(vehicles of
the highway)
13. Anatomy of a fiber: - Core
- Cladding
- Coating

, 14. Attenuation =: The decrease in magnitude of transmission signal strength
between points, expressed in decibel as the ratio of out put to input signal
15. Attenuation [insertion loss] =: Light pulses traveling along fiber are subjected
to loss due to absorption or scattering of the light
16. Intrinsic =: Controlled by the manufacture/expresses in decibels per-kilometer
impacts the signal to reach the receiver with sufficient power
17. Extrinsic =: Controlled by the installer/expresses in decibels per-kilometer im-
pacts the signal to reach the receiver with sufficient power
