True or False: Telephone networks have been converted to fiber, including long distance and metropolitan networks, but fiber to the home (FTTH) is not yet feasible.

• A. True
• B. False
• C. Both are true
• D. FTTH is the only network type not yet converted

Answer: (B)

The idea being tested is whether fiber has reached the access network to homes as well as the backbone and metro parts of the network. In practice, telephone networks have indeed moved to fiber for long-haul and metropolitan sections because fiber provides the needed bandwidth and low latency. Fiber to the home is already feasible and widely deployed in many markets using technologies such as GPON, active Ethernet, and other fiber access standards. Saying FTTH isn’t feasible ignores the real-world deployments that exist and continue to expand, even though some areas still rely on copper or hybrid solutions due to cost or infrastructure constraints. So the statement is false.
