OMS840 Data Sheet

Optimum data delivery

Optical Multiservice Edge OMS840

Marconi's OMS840, part of our world-leading optical portfolio, enables you to reduce the cost of multiservice delivery with customer-located equipment (CLE).

Data services to business customers are an area of significant market activity. But, these new services, whilst consuming high bandwidth, yield relatively low revenue per bit. The challenge therefore is to cost-effectively utilize the widely deployed SDH infrastructure in conjunction with optimized CLE for new customer connections.

Our multiservice devices combine the inherent functionality of Next Generation SDH (NG-SDH) multiplexers with the growing demand for a diverse range of data services. And, as a leader in this market, Marconi is at the forefront of the migration towards multiservice optical networking.

The OMS840 is a compact (1U high) multiservice edge device that allows customers to simultaneously deploy Ethernet services alongside traditional TDM services with rapid payback on investment, providing the most cost-effective ability to progressively migrate to new services and generate new revenue streams. And, with it’s future-proof architecture it allows for the further evolution of the platform technology.

Key benefits Specifically designed for high-speed Ethernet delivery, whilst retaining TDM functionality

Provides rapid payback on investment

Maximizes ROI when used as an extension to SDH networks

Meets customer needs with the world's most popular end-user interfaces

Supports point-to-point or -multipoint data applications

Carrier-class availability and reliability to support a wide range of flexible SLAs


  • GFP for the efficient mapping of Ethernet frames into SDH payloads (VCs)

  • Virtual Concatenation for the efficient use and allocation of network bandwidth

  • LCAS for the flexibility to adjust bandwidth in service.
