TOKYO, Nov. 12 -- Calient Networks, which develops intelligent, all-photonic switching systems, has begun pre-deployment staging for Japan Telecom's all-optical switched network. After a year of joint network design and testing, the companies are moving into end-to-end network configuration and interoperability staging with Calient's DiamondWave system, its generalized multiprotocol label switching (GMPLS) protocol code stack and Cisco Systems' GSR routers. The work is expected to be completed in late December. Calient also announced the first contract sale of its DiamondWave photonic switch,...Read full articleRelated content from Photonics MediaArticlesCombined iXblue-ECA Group Company Takes New Name: Week in Brief: 10/21/22Following Group Gorgé’s acquisition of iXblue last month, ECA Group and iXblue announced that both companies will operate under the common brand name Exail.
