PCCW, Hong Kong’s
PCCW’s 40G OTN network will adopt a series of state-of-the-art technologies, including 80-wavelength 40G, ROADM (Reconfiguration Optical Add/drop Multiplexer), and optical and electrical cross-connection and grooming. These elements allow bandwidth per wavelength to increase by 400% and total transport capacity to jump to 3.2 Tbps, enabling the transmission of 700 DVD files per second. The network also enhances the transmission capabilities of bandwidth-hungry services, due to optical and electrical cross-connection technologies.
