Encryption over 400G DWDM Coherent Wavelength

PacketLight’s 400G capacity over single wavelength muxponders and transponders support secure transport per service or per 400G uplink, with embedded Layer-1 encryption, based on GCM-AES-256 standards. The solution supports Diffie-Hellman (DH) Key Exchange and quantum key distribution (QKD). Encryption over 400G supports the following services: 10/25/100/400Gb Ethernet, 16G Fibre Channel, OTU2/2e, OTU4.

Benefits of PacketLight’s Layer-1 Encryption Solution

  • Encryption of all the data transmitted over the fiber, with no omissions
  • Transparent, maintains full bandwidth of the traffic
  • Beneficial for low latency applications
  • Covering the physical fiber tapping detection
  • Interface with existing DWDM infrastructure and Telco OTN networks
  • No need to change or upgrade Layer-2/3 switch/routers
