Extending High-Speed Services to the Access Network

Demand for high bandwidth services in the metro is increasing, and the access network is the bottleneck.  The Meriton Networks 3300 OSM (Optical Services Multiplexer) provides relief with a WDM services platform that has a low startup cost, single or multiple add/drop wavelength capability, scalable from eight CWDM channels to 40 DWDM channels, and universal interfaces that support client interfaces from 100 Mb/s to 10 Gb/s.  The 3300 OSM universal client interfaces support Fast Ethernet to 10 Gigabit Ethernet interfaces, OC-3/STM-1 to OC-192/STM-64 TDM interfaces, ESCON, FICON, and Fibre Channel for storage area networks interfaces, and D1 Video and HDTV interfaces.

Transparent Wavelength Networking

The 3300 OSM provides intelligent and efficient transport for multiple layer 1 signals across the access and customer premises. The 3300 OSM is a bit-rate and protocol independent transparent OADM (Optical Add/Drop Multiplexer) that is capable of data rates ranging from 100 Mb/s to 10 Gb/s.

Cost-Efficient Platform
Starting with a single client interface and a single wavelength line drop, the 3300 OSM has a low startup cost that removes the financial barrier to entering new markets with wavelength services. The flexible add/drop capability also allows linear cost growth as additional services are provided.

Modular Architecture... CWDM & DWDM
The 3300 OSM architecture scales from eight CWDM channels to 40 DWDM channels to ensure ample room for growth on a single platform. Service interface cards and plug-in optical interface modules can be hot inserted into the shelf to add capacity.

9:1 and 2:1 GFP Sub-Rate Multiplexing

The 3300 OSM further increases the service density and optical efficiency with transparent sub-rate multiplexing interfaces. The GFP protocol is used to multiplex multiple services that can be different protocols onto a 2.5G or 10G wavelength.   For example, any nine Gigabit Ethernet/Fibre Channel optical signals are multiplexed onto a single 10 Gb/s signal or two Gigabit Ethernet/Fibre Channel or eight ESCON/100BaseFX into a 2.5 Gb/s signal.

Flexible Topology Support

The 3300 OSM can be deployed in a ring topology that is found in many of today’s access fiber networks. As well, the 3300 OSM can be deployed in a point-to-point application with a diverse path protection scheme to reach a single building, or a linear network to string multiple sites.

Meriton's Agile Optical Networking portfolio comprises the 3300 OSM at the access layer, 7200 OSP for multi-degree switching in the metro core and the
6400 OTP for flexible transport in metro core-regional networks, all supported by unified network planning and management systems.

Common Management

For network management, the 3300 OSM seamlessly integrates with the Meriton 7200 OSP (Optical Switching Platform) and 6400 OTP (Optical Transport Platform) under the Meriton 8600 NMS (Network Management System) to provide an end-to-end managed metro network for wavelength services.

Simplified Network Engineering

Similar to SONET/SDH, the 3300 OSM can be engineered in a link-by-link fashion. Link engineering is very simple to implement, and can significantly reduce a carrier’s time-to-revenue. Meriton’s simplified engineering is also very cost effective for doing adds, moves and changes, with minimum impact to existing customers.

7200 OSP Direct Interworking

The 3300 OSM interworks directly with the 7200 OSP over CWDM or DWDM interfaces. The elimination of additional OADM nodes and back-to-back optical interfaces at the hub site greatly simplifies the network deployment and offers substantial cost savings.

Intelligent Network Management

Operators can manage the 3300 OSM using either a text-based command line interface or the graphical user interface of the 8600 NMS or the 8300 EMS (Element Management System). The 8600 NMS simplifies management of optical networks by integrating element and network management functions, and automating common operational tasks, including setup, maintenance and teardown of optical paths.  This enables the operator to efficiently manage the equipment as well as the services running on a Meriton network.

Automated Network Planning
One of the key differentiators of the 3300 OSM is that it is supported by Meriton’s fully automated network planning tool, the 9500 NPT. From simulation and verification of optical layer transmission performance, to full traffic planning and engineering, the 9500 NPT presents a unified approach to designing optical networks
