Japan Telecom and Calient Networks begin pre-deployment staging for all-optical network

Nov. 6, 2001--Japan Telecom and Calient Networks have announced pre-deployment staging for the carrier's all-optical switched network. After one year's joint work on network design and pre-testing, the companies are moving into end-to-end network configuration and interoperability staging with Calient's DiamondWave system, Generalized Multi-protocol Label Switching (GMPLS) protocol code stack, and Cisco Systems' GSR routers.

After one year's joint work on network design and pre-testing, the companies are moving into end-to-end network configuration and interoperability staging with Calient's DiamondWave system, Generalized Multi-protocol Label Switching (GMPLS) protocol code stack, and Cisco Systems' GSR routers.

"Photonic switching and GMPLS networking are essential to Japan Telecom to support our rapidly growing data traffic at dramatically reduced cost and to create new services,"says Tetsuya Yuge, managing director of Japan Telecom's Information and Communication Laboratories. "Calient Networks is one of the leading developers to successfully complete testing and demonstration of GMPLS across a multi-vendor photonically switched network. We plan to leverage their performance leadership in our commercial networks."

The pre-deployment staging work begun in October is expected to be completed in late December 2001, encompassing all functional staging of the photonic switching system, rigorous production-level testing of redundancy, reliability, non-stop software operating system testing and interoperability with Cisco GSR routers and GMPLS software.

In operation since 1986, Japan Telecom (Tokyo) serves nearly 20 million users through its Internet and voice services. For more information, visit www.japantelecom.co.jp/english/

Calient Networks (San Jose) develops intelligent, all-photonic switching systems and software that help service providers scale their networks for bandwidth demands and deliver new wavelength services. For additional information about Calient, visit www.calient.net.
