We extend the transmission distance of 400GBASE-LR4 and 400GBASE-LR8 systems by introducing simple and ultrawideband single-stage bismuth-doped fiber amplifiers (BDFAs). The transmission reach of e…
In this work, we present an experimental demonstration of real-time transoceanic space-division multiplexed transmission with coupled-core multicore fibers. To compensate for modal coupling in the …
Since optical submarine cable systems are a part of the global communications infrastructure, their total capacity must be continuously and dramatically enlarged. Recently, methods how to maximize …
Swift and dynamic reconfigurability of network topology, even at the optical layer, is essential for satisfying the various requirements of future networks in diverse areas (e.g., data centers, 5G/…
