Digital Lightwave supports OTN multiplexing test

Digital Lightwave Inc. has announced the availability of enhanced OTN multiplexing test support for its NIC Platform. The new functionality is designed to test the full range of standard multiplex structures as defined within ITU-T Recommendation G.709 from the ODU0 up to the 43G ODU3.

The OTN Multiplexing support includes generation and analysis of ODU0 multiplexed directly into ODU2 (ODTU2.1), ODU0 multiplexed directly into ODU3 (ODTU3.1), and ODU1 multiplexed into ODU2 multiplexed into ODU3.

"OTN network technology and deployments have now reached the stage where carriers expect to be able to multiplex client payloads and manage their bandwidth in the same manner as they did on their SONET and SDH network," said Tony Goodchild, director of product management and marketing. "In order to fully test these OTN networks it is necessary to generate and test client payloads such as SDH and Ethernet that are fully mapped into ODU channels within high speed OTN links. With these additional OTN multiplexing options customers can generate and test any configuration of OTN circuit."

The additional OTN mappings are designed to facilitate testing of any ODU multiplexed circuit, says Digital Lightwave. The new features not only enable the NIC to generate and test the multiplexed payloads, but support the generation and test of Ethernet payloads within those ODU channels, the company adds. The new capabilities thus enable technicians to test real-life payloads.

The OTN test option is available on Digital Lightwave's 40G and Multi-Service Analyzer series of modules (MSA 2020 and MSA 2030) which feature test options for SONET/SDH, OTN, Ethernet, Fibre Channel, and NGN technologies such as Virtual Concatenation, GFP, and LCAS.
