BELL LABS DEMONSTRATES 100 CHANNEL WDM FOR OC-192 OVER 400 KM
Lucent Technologies' Bell Labs division has successfully
demonstrated a 100-channel wave division multiplexing (WDM)
system that carried 10 Gbps traffic over a single fiber strand
for a distance of 400 km, more than double the previous
distance record. The 1 terabit per second experiment used
both 50 and 100-GHz channel spacing, as well as a new breed of
high-power, large-dynamic-range, gain-flattened, ultra-
wideband erbium-doped silica fiber amplifiers (EDFAs). Lucent
said its ultra-wideband EDFAs make feasible 100 WDM channels
based on 100 GHz channel spacing, an ITU standard, or 200 WDM
channel systems using with 50 GHz channel spacing. Brief
descriptions of several other Bell Labs optical experiments,
including a few long haul WDM projects, are also available online.
