We discuss the concept of coarse wavelength-division multiplexing (CWDM) for metro networks. After reviewing the requirements on components such as lasers and
We demonstrate that an asynchronous CSMA/CD protocol with an optical loop-back star coupler can achieve high upstream channel utilizatbn in an Ethernet PON, rea
A high-speed and economical optical local access network system is proposed where bi-directional polarization multiplexing is applied to a bi-directional trans
We proposed and demonstrated a solution for the transparent interconnection of metro access and metro core networks enabling end-to-end wavelength provisioning
A power control scheme to make all ONU channels’ power received at OLT nearly equal is proposed. Implemented by monitoring powers at OLT and sending control m
