Fiber connections Flashcards
What has the core of the internet long used for its connections?
Fiber
why is fiber better for the core of the internet
it has higher speeds and allows for transmission to travel much further without degradation of the signal.
what does fiber use for its connections
light for data transmission
how long can electrical signal travel across a copper cable before it degrades and needs a repeater
thousands of feet
how long can implementations of fibre connections travel before signal degrades
many miles
what is more expensive to lay and produce fiber or copper
fiber
FTTX definition
fiber to the x, where the x can be one of many things. it’s becoming more common to use fiber to deliver data closer to the end user
FTTN
fiber to the neighborhood. fiber technologies are used to deliver data to a single physical cabinet that serves a certain amount of the population. from this cabinet, twisted pair or coaxial cables may be used for the last length of distance
FTTB
fiber to the building, fibre to the business, fiber to the basement. cables to buildings physically enter. fiber technologies are used for data delivery to an individual building. after that, twisted par copper is typically used to actually connect those inside of the building.
FTTH, FTTP
fiber to the home. fiber is actually run to each individual residence in the neighborhood or apartment building. fiber to the premises. instead of a modem, the demarcation point for fiber technologies is known as optical network terminator.
instead of a modem, the demarcation point for fiber technologies is known as
optical network terminator. ONT
ONT
converts data from protocols the fiber network can understand to those that more traditional twisted pair copper networks can understand
