10-Gbps applications are efficient in SONET/SDH-based interoffice transport for multimedia or
videoconferencing services, which have large bandwidth requirements. Ethernet and ATM-based
broadband services for business applications, such as LAN interconnection, multimedia services,
and large file transfers, are also typical of the fast-growing demand for bandwidth in the interoffice
network.
Another bandwidth deployment criterion important to the service provider is the overall reduction of
network updates to accommodate network bandwidth growth. A four-channel, 2.5-Gbps-based
WDM network provides the same capacity as a signal-channel, 10-Gbps-based network, but
requires four times the quantity of network elements and, more importantly, four times the number
of network upgrade events. A 10-Gbps-based solution allows the service provider, with networks
experiencing fast growth, to reduce the number of network upgrades (Figure 2). Additionally, the
10-Gbps networks increase service speed to market, as bandwidth activation above 2.5 Gbps is
not dependent upon activating another 2.5-Gbps channel. 10-Gbps-based networking allows more
nodes to be added on the ring and provides the capability of increasing the number of services
added or dropped at a particular node. In addition, 10-Gbps networks allow the consolidation of
existing smaller rings, simplifying the overall network architecture (less inter-ring connections will
be needed between rings). For presently deployed 2.5-Gbps-based systems, the migration to OC-
192/STM-64 can be fully supported on the Cisco ONS 15454 MSPP while the platform is in
service.

Cisco Solution
The Cisco ONS 15454 10-Gbps solution enables carriers to use their existing fiber plants and
installed bases of Cisco ONS 15454 systems, while providing required services such as DS-1/E1,
DS-3/E3, OC-n/STM-n, Ethernet, ATM, and video over the same Cisco ONS 15454 platform. Other
10-Gbps solutions require the use of additional add/drop multiplexer (ADM) equipment to drop
lower bit-rate services, such as electrical DS-1s/E1s, from their 10-Gbps platforms. The Cisco
ONS 15454 platform allows the service provider to efficiently use the deployed bandwidth, whether
it is a single 10-Gbps channel or a high-bandwidth, multiple-wavelength DWDM solution (Figure 3).
