Startup RBN Inc. has introduced the RBNi 8200 ROADM at the Supercomm 2002 conference. Sporting an "outside plant hardened" designation, the 8200 is deployable in environments from -400F to 850F.

"The 8200 is designed to be a quick upgrade to existing SONET or SDH networks," said Richard Lauder, CTO at RBN. "It's basically plug-and-play CWDM [coarse wavelength division multiplexing]." However, the plug-and-play upgrade comes in a compact, low-cost, highly reliable box, he said.

"We're not saying that it's got the most advanced internal technology; in fact, all the ICs are off the shelf, second sourced and proven. Our intellectual property comes in how we put it all together to deliver four channels of protected OC-48 in a box one rack unit highwith no fansand still be able to operate it in rugged, industrial-like environments."

The design uses external fins for conductive/convective cooling.

Along with SONET upgrades, the box targets DSL loop upgrade, wireless backhaul, broadband multiprotocol transport, and low-cost metro core networks. Pricing for a four-channel protected OC-48 box is $10,000.

RBN specializes in the development of optical transport and switching technologies that were originally focused on metro core and access applications. "We quickly shelved our core work when we saw where that market was headed," Lauder said.
