Product Overview
The Cisco ONS 15540 ESPx is an optical transport platform that employs DWDM
(dense wavelength division multiplexing) technology. With the Cisco ONS 15540
ESPx, users can take advantage of the availability of dark fiber to build a common
infrastructure that supports data, SAN (storage area network), and TDM
(time-division multiplexing) traffic. The system uses an enhanced chassis with front
fiber-optic cable access for optical interconnections between transponders and
optical mux/demux modules.
