Einsof ES-1000TE-Crypto is a multi-rate, multi-service high density wavelength division multiplexing (DWDM) transponder, supporting innovative cryptographic capability for GbE, 10GbE, and 40GbE data storage services. The ES-1000TE-Crypto provides added security benefit to any DWDM link by encrypting the data transmitting between the sites.
Up to 80G Layer-1 encryption
Einsof comprehensive encryption solution assures three major concerns in optical link security:
- Confidentiality – preventing disclosure of information to unauthorized parties
- Data integrity – ensuring that the message has not been altered
- Authentication – validating that both parties involved are who they claim to be

Built-in Layer-1 encryption
Supports GCM-AES-256 hardware-based encryption capability per transponder, providing full throughput without degradation to the service performance.
Flexible Design
On the data level, the ES-1000TE-Crypto performs Layer-1 GCM-AES-256 encryption on the full bandwidth. The encryption provides end-to-end transparency of data and clock, with a low latency of less than 12usec for 10GbE.
Powerful Feature Set
On the management level, the ES-1000TE Crypto supports the secured management protocols HTTPS, SSH, SNMPv3 and RADIUS, based on user password and firewall. The ES-1000TE Crypto also detects degradation in the fiber link performance for automatically detecting possible tapping attempts.
