After an intensive research and development process, Packetlight introduces the new PL-2000AD – a 2x100 Gb/s WDM multiplexer with 400 G capacity in a 19 "enclosure of only 1 elevation unit (~ 4.5 cm). PacketLight is the only company in the world that has managed to deliver this enormous capacity in a compact 1U/HE architecture, with extremely low power consumption, making it ideal for datacenter connectivity. The PL-2000AD platform also optionally supports switchable cyber security features in the form of optical layer1 encryption/Encryption, a response to one of the fastest growing trends last year: Cyber threats. Further developments of the PL-2000AD family will follow soon.
