Abstract

This paper investigates the performance of star–ring hybrid topology networks with optical add and drop multiplexer (OADM) in dense wavelength division multiplexing (DWDM) system with 0.8 nm channel spacing at different bit rates (5, 10 and 15 Gbps) in terms of bit error rate (BER), quality factor and optical signal-to-noise ratio (OSNR). OADM has the capability to add and drop the new channels and provides the wavelength routing between star and ring topologies. It is observed that the hybrid topology supports 128 users on upper and lower ends with 150 km distance between the nodes of ring network without dispersion compensating fiber.

Keywords: bit error rate (BER); dense wavelength division multiplexing (DWDM); optical add and drop multiplexer (OADM); quality factor (QF); semiconductor optical amplifier (SOA)
