Full-Duplex Transmission of FTTX/Ethernet Services in a RSOA Based WDM-PON Architecture using Polarization Multiplexing Technique

摘要

In this paper a simple architecture has been developed for full-duplex transmission of different services like Ethernet, FTTX etc through single optical carrier wavelength employing polarization multiplexing technique in the transmitter end and the user end simultaneously. 10 Gbps and 2.5 Gbps datarates are bidirectionally transported over 50 km single mode fiber (SMF) to provide Ethernet and FTTX services concurrently to the user. Reflective semiconductor optical amplifier (RSOA) is used to reuse and remodulate the downlink signal to uplink transmission. The upstream and the downstream transmission performances are observed by the bit error rate (BER) values and the eye diagrams obtained by the BER analyzer at both ends.
