Cisco Upgrades Optical Multiservice Transport

Cisco Systems unveiled hardware and software upgrades for its Cisco ONS optical networking portfolio that give service providers and enterprises greater flexibility in delivering new services as well as more ability to scale their networks and manage their optical infrastructures.

The new capabilities include:

  • 10-Gbps data muxponder; a unit that provides data and storage services aggregation over a 10 Gbps wavelength, allowing a variety of data and storage services to be efficiently bundled and transported over a single optical wavelength;

  • 32-channel ROADM-based long-band (L-band) solution, which includes ROADMs and optical amplifiers, transponders and muxponders. These units allow up to 32 wavelengths (100 GHz-spaced) to be transported in the L-band region of the transmission spectrum;

  • Full center-band (C-band) and L-band tunability for 10-Gbps transponder and muxponder cards on 50GHz channel grid;

  • Enterprise systems connection (ESCON) support on 2.5-Gbps data muxponder;

  • Multi-shelf management, which allows centralized provisioning and management of multiple shelves at each DWDM node location;

  • Network-level alarm correlation, which provides simplified trouble-shooting capabilities for an MSTP-based DWDM network, resulting in quicker root cause determination and problem resolution;

  • Future in-service mesh/multi-ring upgrade capability for ROADM-based networks requiring multi-degree applications; and

  • Alien lambda support, which allows for insertion of 10 Gbps or 40 Gbps non-ONS wavelengths into the ROADM network. This means the possible direct interconnection of routers and switches, enabling the elimination of transponders in some cases.

TietoEnator, an international information technology (IT) services provider based in Finland, is using the most recent Cisco ONS 15454 platform upgrades to provision new high speed customer site connections much more rapidly via software.

DataGroup, a Ukrainian telecommunications company, recently introduced a new portfolio of high-capacity services based on the Cisco ONS 15454 Multiservice Transport Platform (MSTP). The new 6500-kilometer countrywide fiber-optic network provides the DWDM backbone for delivering Ethernet-based services in all regional centers of Ukraine.
