Calient Networks® and EdenTree Technologies® Sign Exclusive Reseller Agreement for Network Lab Automation Solutions

The companies enhance their partnership and integration of EdenTree Lab Manager and Calient DiamondWave products

Calient Networks, a leading supplier of carrier-class fiber optic cross-connect systems (FOCS), and EdenTree Technologies, innovator of software solutions for lab management and test automation, today announced that the companies have signed an exclusive technology and distribution agreement for integrated network lab automation solutions.

EdenTree’s Lab Manager software, the Lab Operating System™ and leading software platform for managing, scheduling, configuring, and tracking lab resources, has been integrated with Calient’s DiamondWave® family of all-optical switches for more than two years, providing a drag-and-drop graphical user interface (GUI) and API for controlling the switches in lab environments. In April 2006, the companies announced a reseller agreement that expanded on their existing technology relationship.

Today, EdenTree and Calient announced an agreement whereby EdenTree will become Calient’s exclusive reseller of DiamondWave switches into the labs of network equipment manufacturers and service providers. The agreement excludes government, military, and university customers. Further, the companies have expanded their integration to include Calient’s new FiberConnect fiber optic cross-connect switch, and tightened their product integration with powerful new features that allow users of EdenTree Lab Manager to manage optical power levels and obtain optical status information directly from Calient switches.

The joint solution has been in use in multiple customer labs for two years, with an accelerated wave of new customers adopting the solution. “EdenTree’s rapidly growing sales organization is encountering more and more customers needing cost-effective all-optical switching infrastructure in their labs,” said Jay Oyakawa, president and CEO of EdenTree Technologies. “Calient’s FiberConnect is the most cost effective all-optical switch on the market, allowing us to offer our customers a scalable solution for automating optical connections in labs of any size.” Oyakawa continued, “We are pleased that Calient recognizes EdenTree’s significant market presence and has entrusted us to be its exclusive reseller to labs.”

Lab Manager’s drag-and-drop GUI allows test engineers, developers, customer support personnel, and other lab users to design and schedule test topologies consisting of devices that are interconnected by DiamondWave AFM and FiberConnect switches. The solution transparently and dynamically builds the topologies, eliminating manual recabling and providing automated and remote control of test topologies, easier sharing of equipment, and a dramatic increase in test velocity.

Kevin Welsh, CEO of Calient, stated. “EdenTree is an ideal partner for Calient, providing our lab customers with a complete lab automation solution that incorporates DiamondWave high reliability switches and EdenTree’s market-leading lab management and automation software products.”

Existing customers of the combined Calient and EdenTree solution include Cisco Systems, Fujitsu, Nortel, AT&T, and Verizon.

In addition to Calient’s all-optical switches, EdenTree manages other physical layer switches and power switches from industry-leading manufacturers.
