Alcatel-Lucent 1665 DMX offers WDM optical transmitters for main optical packs and also offers non-integrated mux/demux, optical amplification and transponders through the Wavelength Extension Services (WES) portfolio. WDMX is the integration of these types of WDM functions directly on the Alcatel-Lucent 1665 DMX shelf platform. It provides metro transport markets with a state of the art low-cost converged MSPP/MSTP solution for both TDM and WDM. The LNW705 supports this integration on Alcatel-Lucent 1665 DMX.
WDMX comprises feature sets that add the ITU-T Optical Transport Network (OTN) layered structure for WDM within the Alcatel-Lucent 1665 DMX shelf footprint. The optical transport network layered structure consists of optical channel, optical multiplex section and optical transmission section. Pre-existing Alcatel-Lucent 1665 DMX WDM interfaces may also be directly connected to the optical multiplex section without using the ITU defined optical channel encapsulation.
WDMX is designed for application by service providers in metro access, metro core, and extended metro deployments, as well as high capacity enterprise and campus networks.
Alcatel-Lucent 1665 DMX R7.1.1 provides a great solution to the low cost Triple Play (voice, video and data) distribution application focusing on data rates below OC48.
Service providers are dealing with the problem of enhancing video distribution and Ethernet broadcast distribution and making it affordable. WDMX is perfectly matched to meet a major portion of that need.
Some customers have a requirement for full C-band tunable lasers and very long reach without regeneration for their video backbone networks. Although WDMX is not intended as a full range multi-haul system, it can lead to dramatic savings for the service provider. WDMX is expected to be the first system to focus the latest full set of optimized technologies for metro deployments.
Video applications typically have a two tiered network. One tier consists of national video broadcast feeds through a national core network into local Video Broadcast (VBC) and Video-On-Demand (VoD) servers at the regional and local Video Hub Offices (VHO). The second tier connects the VHOs with Video Service Offices (VSO). The VSO distributes the multicast VBC paths and manages the unicast connections for VoD paths.An Ethernet Aggregation Router collects and distributes traffic to and from DSLAMs and routers in the access network.
The typical VSO will house 2 Edge Aggregation Routers (EARS). Each of the EARs will interface to:
This is a total of 6 to 9 GbE. So, most VSOs will require less than 8 wavelengths. However, the VHOs and Optical hubs will require more than 8 wavelengths.
There are cases where there is a large jump in high bandwidth service demands along the path of an existing MSPP ring. If such services are projected to exceed the ring capacity (capacity exhaust), WDMX can be used. Alcatel-Lucent 1665 DMX R7.1.1 allows an existing partially filled Alcatel-Lucent 1665 DMX shelf to add 10G wavelengths for client interfaces with data rates of OC-48 or below. The wavelengths added are passed transparently, which is critical to applications that would lose proprietary functionality if the client signals attempted to use standard section and line termination of SONET for transport.
The substantial disasters of the last ten years have caused both industry and the government to require geographical redundancy of mission critical data in real-time or near real-time to assure high availability. This requires substantial high capacity transport of Ethernet and Fibre Channel data for Fortune 1000 Enterprises.
