  • ATM/SONET Device (OC-3c, OC-12c, OC-48c)
  • ATM-only Device (OC-192c)
  • Encrypts multiple levels of security
  • Supports single user or multi-user computer-based group
  • High Speed Performance
  • Up to 10 Gb/s for ATM
  • Up to 2.5 Gb/s for SONET/SDH
  • Uses public networks, eliminating cost for leased lines and provisioning of redundant paths

  • Enhanced FIREFLY (key generation)
  • NSA Notification on Enhanced FIREFLY Distribution


FASTLANE incorporates the multi-rate interface card that allows users to select ATM or SONET/SDH encryption at STS-3/STM-1, STS-12/STM-4 or STS-48/STM-16 rates without changing the line cards.


FASTLANE incorporates recognized standards and is interoperable with GD's NSA-Certified encryptor, the TACLANEŽ-Classic (KG-175), while in ATM mode. FASTLANE can also be managed by GEM encryptor management software while in ATM mode.
