Optical Networking

Over the last decade, the demand for high capacity transmission at a reduced cost has been driven by the rapid spread of applications such as the Internet, audio/video and digital services. Packet optical transport networks provide a common platform for all the transport requirements of these applications. With the maturing of these networks, equipment vendors now need to support advanced features such as higher optical fiber capacities, restoration capabilities, wavelength services, etc.

Aricent has comprehensive expertise in the development, testing and sustenance of telecom equipment that use optical technologies to transport packetized traffic. These skills enable Aricent help its clients to effectively address critical issues such as technology choices and product design.

Customer Challenges

Typical challenges faced by optical equipment manufacturers include:

  • Need to support diverse traffic types over a combination of transport options
  • Build in support for native switching of transport technology and streamlined resource allocation
  • Support GMPLS-ready unified cross-layer management which provides a single provisioning tool for multiple technologies (packet, optical and photonic)
  • Provide integrated OAM including end-to-end fault management, performance monitoring, protection, high availability and fast fault localization
