TCC Announces Affordable, Strategic-Level Data Encryption for Optical Networks

Maximum performance, security and ease of use with automated KEYNET management and protocol-agnostic technology

CONCORD, Mass.--(BUSINESS WIRE)-- Technical Communications Corporation (NasdaqCM: TCCO) announces its interoperable family of DSD-72B-SP SONET/SDH path encryptors, providing global, strategic-level security to prevent interception of all types of communications transmitted over fiber optic networks, while being easy and cost-effective to implement and manage.

John Maher, director of Engineering and Product Development at TCC, said, “DSD-72B-SP encryption devices integrate seamlessly as a network overlay on existing networks — no network modification is required, network performance is not affected, and encryption devices are only needed at the end points of the network.”

SDH/SONET headers are transparently processed, allowing the DSD-72B-SP to interoperate with any standard SDH or SONET network element such as multiplexors. Individual path virtual container data payloads are encrypted, leaving the path overhead unencrypted for unrestricted network switching of each VC with no plaintext exposure of the path-encrypted data payload.

Automated Key and Device Management

The DSD-72B-SP secure network is centrally deployed, configured and managed by TCC’s advanced online KEYNET Optical Manager. Network policies are supported, and automated key management, logs, alerts and polls provide trusted secure communications.

“With KEYNET, a network expert is not needed to manage network security. The level of security and ease of use of KEYNET, combined with the efficiency and performance of our protocol-agnostic technology, makes DSD-72B-SP encryption a cost-effective investment,” added Maher.


The DSD-72B-SP is a FIPS 140-2 Level-3 designed, hardware-based encryption device in a tamper-proof, rack-mountable appliance using three-tier symmetric key management with AES 256-bit algorithm. National algorithms can also be integrated without hardware modification.


The DSD-72B-SP is exportable and operates at either 622.08Mb/s or 155.52Mb/s, and is available in industrial, government and military variants. Contact TCC Sales at 978-287-5100,
