Metro Fiber Comparison

1. Directly-Modulated (DM) lasers are implicitly cheaper than lasers with integrated or external modulators. However, they suffer from a large optical chirp, which depends strongly on laser design.
2. Fortunately, fiber designs with negative dispersion can help mitigate the chirp problem.
3. VPItransmissionMaker™ WDM allows negative dispersion fibers to be evaluated over a wide range of laser types, represented by simulation models or direct measurements.
4. Parameters may be swept deterministically or randomly to represent manufacturing variations, and a Yield Estimation performed based on one or more performance metrics.
