Abstract
A cost effective bidirectional wavelength division multiplexing (WDM) self-healing rate (SHR) network using bidirectional add/drop amplifier (BADA) modules was demonstrated. The restoration time was measured to be less than 2 ms. The bandpass filters within the BADA modules were proven to be very effective in reducing the relative intensity noise (RIN) caused by Rayleigh backscattering and optical reflections. In fact, there was no observable degradation in the receiver sensitivity caused by RIN. Thus, the scalability of the proposed network would be limited by the accumulation of amplified spontaneous emission. Results showed that this network could accommodate about 14 nodes when the node spacing is 80 km.
