Data Sheet

The Cisco ONS 15454 MSTP can be configured to support any metro, regional or core DWDM topology, allowing a

single solution to be used for the overall network, independently from the topology and reach. The ultimate topology

flexibility is achieved through a set of fully reconfigurable optical add/drop multiplexer (ROADM). Multi-degree

ROADMs (2 through 8 degrees of freedom) allow wavelengths to remain in the optical domain while being passed

from one ring or network segment to another, further eliminating the need for OEO conversions and leveraging the

ability of core routers to initiate DWDM-compatible wavelengths (Figure 2).

Figure 2. Cisco Next Generation network strategy

The Cisco ONS 15454 MSTP offers ROADM capability that allows zero to 40 channels of pass-through or add/drop,

A-Z wavelength provisioning, and full real-time power monitoring of each individual wavelength. Keeping traffic

purely in the optical domain as much as possible has the added advantage of "future-proofing" a transport network.

Pure optical transmission is inherently more tolerant to bit-rate variations where moves to higher rates and new

protocols may still be required in the future, and hence more robust because photonic processing is intrinsically

insensitive to protocol changes, unlike typical electrical processing elements.

Product Specifications

With its multiservice capability, innovative optical technology, automatic optical power management, and MSPP-like

ease of use, the Cisco ONS 15454 MSTP transforms how DWDM networks are built and managed. Combining

multiple services and intelligent DWDM, the Cisco ONS 15454 MSTP significantly reduces both capital expenditures

and operational expenses for today’s metro and regional networks.
