Ciena Corporation

Ciena optical networking appliances provide high-capacity wavelength division multiplexing (WDM) and optical transport solutions for telecommunications carriers, data centre interconnects, and enterprise networks. These platforms deliver terabit-scale optical connectivity with integrated encryption and advanced photonic capabilities. 

From a security monitoring perspective, Ciena optical appliances generate system logs covering equipment alarms, configuration changes, authentication events, and link status changes. Integrating these logs enables visibility into the physical network transport layer, detecting unauthorised configuration changes, hardware anomalies, and potential fibre-tap indicators.
