2.5-GBPS MULTIRATE TRANSPONDER CARD FOR THE CISCO ONS 15454

MULTISERVICE TRANSPORT PLATFORM

The Cisco

ONS 15454 Multiservice Transport Platform (MSTP) support for a 2.5-

Gbps multirate transponder card simplifies the integration and transport of many

service types, including Enterprise Systems Connection (ESCON), Fibre Channel,

Gigabit Ethernet, SONET/SDH (to 2.5 Gbps), and video interfaces and services

into enterprise as well as metropolitan (metro) and regional service provider

networks.

BACKGROUND

Metro transport networks must support a wide variety of service demands, from low-rate DS-1/E-

1, DS-3/E-3, 10/100BASE-T, OC-3/STM-1, etc., to higher-rate OC-12/STM-4, Gigabit Ethernet,

OC-48/STM-16, and 10 Gigabit Ethernet services. In the recent past, SONET add/drop

multiplexers (ADMs) provided the services platform to aggregate and transport services up to

OC-48/STM-16, where metro dense wavelength-division multiplexing (DWDM) platforms were

designed for optical signals from OC-3/STM-1 to OC-192/STM-64, including Gigabit and 10

Gigabit Ethernet. Unfortunately, deploying multiple platform types, including metro DWDM and

SONET ADMs, to support the wide variety of services is not cost effective for many service

provider and enterprise networks. Thus, a more cost-effective networking solution is required to

enable the delivery of all services, from lower-speed DS-1/E-1s to higher-speed 10 Gigabit

Ethernet and OC-192/STM-64s.

PRODUCT OVERVIEW

The 2.5-Gbps multirate transponder (2.5G transponder) card (Figure 1) provides the capability to transport a wide variety of service types from

155 Mbps to 2.48 Gbps, including services such as ESCON, SONET OC-3 through OC-48, SDH STM-1 through STM-16, Gigabit Ethernet, 1-

or 2-Gbps Fibre Channel, and other services, over a 100-GHz, ITU-compliant wavelength, with 50-GHz wavelength stability for future 64-

channel operation. The 2.5G transponder card architecture contains a single client interface that is mapped to a single-line DWDM interface,

without accessing the Cisco ONS 15454 shelf cross-connect fabric.

The interface to the client is via a variety of Small Form-Factor Pluggable (SFP) optics modules, enabling a wide service mix, including

ESCON, OC-3/STM-1, OC-12/STM-4, OC-48/STM-16, Gigabit Ethernet, 1-Gbps Fibre Channel/FICON, 2-Gbps Fibre Channel/FICON, as

well as high-definition television (HDTV), D1/SDI video, DV6000, and different fiber types (single- and multimode), wavelengths (850 and

1310 nm), and fiber reach (short reach/intra-office, intermediate reach/short haul, etc.). The SFP optics modules are equipped with LC

connectors to enable high-density placement on the card.
