It is rather safer and less expensive at the CPE to have a broad receiver and a narrow transmitter. Fiber still obeys power density rules. Not to mention that passive splitting of the downstream and driving with high power lasers couple with either Raman or Erbium-doped fiber amplifiers saves money for the carrier.

Running a dedicated fiber pair to each customer is expensive; CATV fiber supertrunk digital systems are well-tested at high (>+30dBm optical) powers and are much less expensive for the carrier, meaning they are much less expensive for the subscriber, too. Even if they *are* oversubscribed.

Even fiber.

Is this residential? One can get 1G symmetric fibre from HKBN for less
than 30USD/mnth if you live in a block of apartments. See below. (Please
note troll hat on my head)
