Modules

The Cisco TNC, TNCE, TSC, and TSCE cards incorporate a highly stable Layer 3 internal timing reference to provide system timing based on input received from an external BITS source or from an incoming SONET or SDH optical signal. Synchronous status messaging helps the system select the best timing sources, and a holdover mode maintains timing accuracy when preprovisioned synchronization references are not available.

The Cisco ONS 15454 MSTP offers an enhanced optical amplifier card operating in the C-band region of the optical spectrum to extend the reach and capacity of a metro, regional, or long-haul network. The optical amplifier cards are part of the Cisco ONS 15454 MSTP intelligent DWDM architecture engineered to reduce DWDM complexity and speed the deployment of next-generation networking solutions.

The Cisco ONS 15454 optical amplifier card is plug-in modules that take advantage of proven Cisco ONS 15454 carrier-class features. This card delivers the reach and optical performance to support a single DWDM channel all the way to 40 channels today (designed for 80- wavelength operation) to meet the requirements of service provider and enterprise networks. The optical amplifier plug-in card types available for the Cisco ONS 15454 MSTP with the applications they are designed to support.
