Packet Optical Transport—A Viable Solution to Network Expansion

Packet optical transport (POT) networks are optical super-highways that use the most advanced technological enablers, from reconfigurable optical add/drop multiplexers (ROADMs) to amplifiers—and from very high bit rates to dense wavelength-division multiplexers (WDMs).
