Coppers vs Fiber Optics

There is little point in doing a systematic comparison os coppers vs fibers. Fiber is clearly the superior transmission medium. Copper technologies continue to exist primarily based on the availability of existing copper plant. The development of singlemode optical fiber with its nearly unlimited bandwith has unlocked the possibilities for massive deployment of long-haul and metro point-to-point (P2P) fiber optic networks resulting in 3 important changes:
  • Huge capacity increases
  • Substantial cost reductions in equipments, operations and maintenance
  • Significant improved quality of services (QoS)
FTTH Architectures

Active and passive are two commonly used FTTH architectures for FTTH deployment. Active Architecture is also called as Point to Point(P2P) and Passive Optical Network (PON) architecture is called Point to Multi Point(P2M). Choice of active or passive architectures for deployment depends on the type of services to be delivered, cost of the infrastructure, current infrastructure and future plans for migrating to the new technologies.
