BICSI - ✔️ - Building
Frequency - ✔️ Optical pulses using cycles per second, 1 unit of hertz = 1 cycle per second 4hz = 4 cycles per second Definition of transmission - ✔️ The movement of information in the form of electrical or optical signals from one point to another through a transport medium Refraction - ✔️ Bending of the light as it passes from one medium into another 1 / 2
MHz - ✔️ - Quantifies the bandwidth of a cabling system in a frequency range
- Information handling capabilities of the medium
- Number of bits information that can be transported over the
- Cladding
- Coating
- Impacts the ability of the signal to reach the receiver with sufficient power
- / 2
Megabits - ✔️ - transmission rate
medium(vehicles of the highway) Anatomy of a fiber - ✔️ - Core
Attenuation = - ✔️ The decrease in magnitude of transmission signal strength between points, expressed in decibel as the ratio of out put to input signal Attenuation [insertion loss] = - ✔️ Light pulses traveling along fiber are subjected to loss due to absorption or scattering of the light Intrinsic = - ✔️ Controlled by the manufacture/expresses in decibels per- kilometer impacts the signal to reach the receiver with sufficient power Extrinsic = - ✔️ Controlled by the installer/expresses in decibels per- kilometer impacts the signal to reach the receiver with sufficient power Attenuation loss = - ✔️ - Expressed in decibels per kilometers
dBm = - ✔️ Optical power referred to as 1 milliwatt of power CWDM = - ✔️ Coarse wave division multiplexing DWDM = - ✔️ Dense wave division multiplexing APC - ✔️ Angle polish connector SCS = - ✔️ Structured cabling system Tight buffered = - ✔️ Zipcord
