CeBIT - Cisco enhances DWDM platform

Cisco Systems wants businesses to aggregate storage network traffic and other services over the same wide-area fibre connections, as it moves increasingly into the video post-processing market, a vast consumer of bandwidth.

The company announced two enhancements to its ONS 15530 Multiservice Aggregation Platform here at the CeBIT trade show yesterday, with the aim of combining San (storage area network) traffic with other services such as Gigabit Ethernet over a single optical fibre link using DWDM (Dense Wavelength Division Multiplexing).

DWDM systems transmit multiple signals simultaneously down a single optical fibre by transmitting each one on a different wavelength, or colour, of light.

"With a DWDM platform like this, we are able to put storage and other applications across a single fibre ring," said Geraint Anderson, vice president of optical and PTT marketing for Cisco in Europe, the Middle East and Africa.

The Eight-port Fibre Channel/Gigabit Ethernet Aggregation Card can be used to combine up to eight Fibre Channel, FICON (fiber connectivity) or Gigabit Ethernet signals on a single 10G-bps (bits per second) wavelength in a DWDM system, while the 2.5G bps ITU Trunk Card can be used to combine multiple ESCON (enterprise system connection), Fibre Channel, FICON or Gigabit Ethernet services over a single ITU (International Telecommunication Union) wavelength.

Where such services are carried between sites over a MAN (metropolitan area network) fibre ring, the 2.5G-bps ITU Trunk Card can be used to add or drop a few services on the fibre at each site.

Cisco did not announce the price of the new cards or when they will be available.
