FiberLab fiber network simulators and fiber latency solutions are available in any fiber type and length. They are available in standard fiber test boxes and use optical fiber spools for fiber network simulation. Dispersion Compensation Fiber Modules Compensation for G.652 & G.555 fibers Spool, module, or rack-mount Choice of connector type Custom configurations available Dispersion compensating fiber from M2 Optics is used for correcting dispersion effects created over distances within optical fibers. These specialty fibers are offered in a variety of housings, making them ideal for most dispersion testing and research requirements. DC fiber is available for dispersion and dispersion slope of G.652 and G.655 fibers, such as SMF-28e+ and LEAF, in both C-band and L-band. We welcome inquiries for custom solutions with other fiber types or dispersion requirements (positive, flat-slope, etc).
