PON vs. distributed point to point architecture?
The main advantages of a PON network is no intermediate electronics or powering is necessary between the HE and the subscriber’s home and consequently its operational simplicity. A distributed point to point network topology is essentially designed to cover the “last mile” and normally requires power at the node. However because the nodes of existing CATV networks are already powered no additional power supplies are necessary. PON solution whereas is based on ATM (APON) or Ethernet technology (EPON), are proprietary systems and provides a shared communication architecture. The distributed switched network architecture completely support the Ethernet standard and have all its advantages (no sharing, low-cost components and large availability of data transmission equipment such as transceiver, switching, plug and play facilities). It provides nearly unlimited bandwidth and is entirely open to various technologies. Optical node-based infrastructures can be quickly and easily deployed, all
