2.7 Fiber Connections Flashcards
What does FTTC stand for?
Fiber to the Curb.
What does FTTP stand for?
Fiber to the Premises.
How does FTTC work?
Fiber runs to a curbside pedestal, with copper used for the final connection to the home.
How does FTTP work?
Fiber is run directly into the building, eliminating copper bottlenecks.
What is the main limitation of FTTC?
The final copper connection limits speed and increases latency.
What is the main advantage of FTTP over FTTC?
FTTP eliminates copper bottlenecks, providing faster and more stable speeds.
What device is required inside a building for FTTP?
ONT (Optical Network Terminal).
What is the function of an ONT?
Converts fiber signals into standard Ethernet or fiber connections for routers.
Why is FTTP considered future-proof?
It provides symmetrical speeds and supports high-bandwidth applications.
What type of cables are used in the last segment of FTTC connections?
Twisted-pair (RJ45) or coaxial cable.
What is the typical speed of FTTP connections?
1 Gbps symmetrical or higher.
Why is FTTC more common than FTTP in some areas?
FTTC is easier and cheaper to install than full fiber deployments.
Which technology is expanding rapidly among ISPs?
FTTP, as it offers superior performance and scalability.
What is the key drawback of using copper in FTTC?
Signal degradation over distance reduces speed and reliability.
What is the best choice for high-speed and low-latency internet?
FTTP.
Which ISP service is an example of FTTP?
AT&T Fiber, Google Fiber, and Verizon Fios.
What type of internet connection supports symmetrical upload and download speeds?
FTTP.
What is the benefit of fiber-optic internet over copper-based connections?
Higher speeds, lower latency, and no electrical interference.
How do ISPs convert fiber-optic signals for consumer use?
Using an Optical Network Terminal (ONT).
Which fiber-optic connection is more commonly found in urban areas?
FTTP, due to its higher speed and future-proofing.
