ADVA Optical Networking says its trial of a direct-detection 100G solution in the metro network of a Tier One European carrier “ran error-free under real-life conditions with unfavorable fiber characteristics. The trial demonstrated the potential of non-coherent technologies for low-latency applications in metro and enterprise networks.”
The demonstration was part of ADVA’s engagement in the 100 GET metro project, partially funded by the German Ministry of Research and Education. The 100G demonstrator was built from a simplified set of optical and electronic components, ADVA says, and to reduce power consumption, no digital signal processing at the transmitter or receiver was used. This resulted in a low-latency 100G system. ?
Notes Christoph Glingener, ADVA’s CTO, “There is a market for 100G solutions outside the traditional long-haul space. In the metro and data-center connectivity domain, users need low latency, a small footprint, low power consumption and aggressive price points. This trial was excellent proof that we can deliver against these requirements.”
He continues, “The lessons learned in this trial will benefit our commercial product offerings, which we will launch in 2011, and solidify our leadership position for high-performance, low-latency networks.”?
