BTI Makes the Metro Dynamic
BTI Systems Inc. is outfitting its 7000 series equipment with the ability to adjust optical power on the fly, so they don't have to manually adjust the optical network node by node every time something gets out of whack.
The company's announcement Tuesday morning includes new ROADM and amplifier cards for the 7000. The really interesting part, though, is an optical control system, added to the 7000, that will rebalance optical power automatically.
The feature is called the Dynamic Optical Layer, and it's due to ship "in September," BTI officials say, fully aware that September starts on Thursday.
Why this matters
The long-haul network already has these capabilities, but BTI appears to be the first to bring them into metro/aggregation networks. Increased automation has been a strong trend in optical networking as equipment vendors try to find ways to make their gear cheaper. Lowered operating expenses -- such as avoiding those manual reconfigurations to the optical network -- are a big component of that.
It's worth noting that Infinera Corp. (Nasdaq: INFN)'s metro gear can do this rebalancing. But Infinera's equipment simply avoids the problem by restarting every wavelength at every node, so optical power doesn't fade as a signal passes through multiple nodes.
