- 1Fiber OpticA technology that uses
glass or plastic threads to transmit data using light. - 2CoreThe center of the
fiber - 3CladdingOptical material that surrounds
the core and traps the light in the core.
1 cladding is 125 microns - 4Total Internal ReflectionA technique to trap
light in the core - 5What do you strip off the fiber for termination or splicing?The buffer
- 6Primary buffer coatingA hard protective plastic covering that protects the glass from moisture or physical damage.
They can be either 900 microns or 250 micron - 7Fiber optics are immune to.....Electromagnetic interference
- 8Multi-mode fibersFibers that Support many propagation packs or transverse modes ( ray of light)
- 9Single-mode fibers are used forCommunication links longer than 1,000 meters (3,300 ft.)
- 10AttenuationLoss of optical power or reduction in the strength of a signal
- 11OTDROptical Time Domain Reflectometer
- 12KilometerMetric unit used to measure distances between geographical places on land.
1 Kilometer = 1,000 meters - 13MicronA unit of length equal to one millionth of a meter, used in many technological and scientific fields.
1 inch = 25,400 microns - 14NanometerThe nanometer is commonly used to specify the wavelength of transmitted light .
1 nanometer -= 1 billionth of a meter - 15ModeA defined path in which light travels
A single magnetic field pattern (ray of light) that travels in the fiber - 16Single mode fiberSingle-mode fiber is for long distances and uses one beam of light.
Core = 9 microns
Buffer coating = 250 micron
Laser wavelength
= 1310 or 1550 nm - 17POFPlastic Optical Fiber
- 18Plastic Optical FiberUsed in consumer HiFi and starting to be a new standard in car communication systems.
Core = 1 mm multimode fiber
Used for short, low speed networks. - 19CableProtects the fibers
- 20JacketTough outer covering on the cable. Also used the meet fire codes.
- 21Strength MembersAramid fibers used to pull the cable.
- 22ArmorDiscourages rodents from chewing the fiber cable
- 23ConnectorA non-permanent device for connecting 2 fibers or fibers of equipment where they are expected to be disconnected occasionally for testing or rerouting.
- 24FerruleA tube which hold a fiber for alignment, usually part of a connector.
- 25SpliceA joint between two fibers
- 26Mechanical SpliceA temporary splice where the fibers are aligned by mechanicals means
- 27Fusion SpliceA permanent splice created by welding or fusing 2 fibers together
- 28Demarcation BoxThe physical point wich
- 29BandwidthThe amount of data that can be carried form one point to another.
- 30Decibels (dB)A unit of measure of optical power which indicates relative power loss.
- 31Optical LossThe amount of optical power lost as light is transmitted through the fiber.
- 32Optical PowerIs measured in dBm (decibels) that measures gain and loss.
- 33ScatteringThe change of direction of light after striking small particles that causes loss in optical fiber.
- 34WavelengthThe color of light, usually expressed in nanometers
