Thales and Alcatel Encrypt DWDM Wavelengths

Thales and Alcatel announced a breakthrough in securing DWDM wavelengths -- a capability especially suited for financial and government applications. While traditional DWDM-based encryption services have been limited to the entire fiber, Thales and Alcatel have demonstrated per-wavelength encryption.



The Thales SONET "Datacryptor" has successfully demonstrated encryption of an aggregate SONET signal generated by an Alcatel 1677 SL provisioned with optional DWDM modules and Erbium Doped Fiber Amplifiers (EDFA). In addition to providing DWDM-based encryption, the testing validates that the Thales SONET Datacryptor does not introduce significant delays or impairments when used with ITU optics for SONET protection schemes, including Linear, Unidirectional Path-Switched Ring, and Bidirectional Line-Switched Ring.



The Datacryptor SONET devices are transparent to the Alcatel SONET switching equipment and offer customers scalability and central management. All of the Datacryptor products including the low speed link, T1/E1, T3/E3, 10/100M IP, Gigabit Ethernet and, SONET (OC-3, OC-12, OC-48, OC-192) can be managed by a single secure management application. The Element Manager is a key differentiator for the Datacryptor products.
