A novel WDM-PON scheme with real time monitoring characteristic based on time-sharing method is proposed. Bit error rate (BER) test in 2.5 Gb/s times 27 km is performed with small power penalty is observed.
We propose and demonstrate a method for simultaneous real-time status monitoring and troubleshooting of a high-capacity single-fiber bidirectional passive optical network (PON) that is based on wavelength-division-multiplexing (WDM) techniques. To avoid interference between the bidirectional traffic, downstream and upstream signals are assigned in different… (More)
A power-compensated, bidirectional reconfigurable optical add/drop multiplexer is proposed. The system performance is built on a bidirectional 4 x 2.5 Gb/s 50 km transmission with only 0.2 dB of power penalty compared to unidirectional transmission.
