Abstract
We investigate a transparent WDM ring network design immune to accumulated
power transients where simultaneous bidirectional operation is achieved on
a single fiber. This allows cost effectiveness, flexible traffic re-routing,
and network operation. We demonstrate that add/drop of 15 out of 16 channels
generate negligible $({< 0.15}~{\hbox
{dB}})$ power excursion on the surviving channel. These results
have been obtained by using new high-gain erbium-doped waveguide amplifiers
in an innovative gain-clamped configuration that allows bidirectional operation.
The glass-on-silicon waveguide optical amplifiers are able to achieve a clamped
flat gain of 15 dB on full C-band with up to 0-dBm input power. This is the
highest output power ever reported for an erbium-doped waveguide amplifier.
The amplifier can with almost identical performance operate with signals entering
together from both ends or even from opposite ends. The gain properties of
the amplifier are almost perfectly symmetric.
