High-margin component technology for the optical layer of transport networks has been dominated in the past half decade by the lucrative long-haul sector. For wavelength-division multiplexing, the optical metro market has been pulled in conflicting directions by the need for lower cost but almost the same performance as long-haul. High component costs has in turn inhibited adoption of pure optical solutions in the metro network. In the past year, crowding the optical component space, a slow-down in North American long-haul deployments, and the rise of a new generation of metro equipment has driven increased efforts from suppliers to produce components specific to metro needs. In this talk, we will examine how metro components differ from their long-haul counterparts and the factors that will affect their market acceptance.
