We report a two-span, 67-km space-division-multiplexed (SDM) wavelength-division-multiplexed (WDM) system incorporating the first reconfigurable optical add–drop multiplexer (ROADM) supporting spatial superchannels and the first cladding-pumped multicore erbium-doped fiber amplifier directly spliced to multicore transmission fiber. The ROADM subsystem utilizes two conventional 1 × 20 wavelength selective...
We report lab measurements of joint digital signal processing of simultaneous 112Gbps links in a 7-core fiber. Strongly-correlated phase fluctuations between the cores permit reduced processing complexity with no increase in the bit-error ratio.
We demonstrate a real-time, single-wavelength, coherent 100 G PM-QPSK upgrade of a field system. Performance sufficient for error-free operation after forward-error-correction was achieved over installed 900 km and 1800 km links, proving the viability of seamless 100 Gb/s upgrades.
We demonstrate a broad, wavelength flexible SOA-Raman hybrid amplifier for metro/access networks. Using highly nonlinear fiber as the Raman gain medium, the amplifier has all the advantages of a discrete device.
