Abstract : The goal for the matched-clad dual-mode fiber was to duplicate the low bending losses exhibited by high-delta fibers (delta as large as 1%), which are the lowest bending loss fibers available for long-haul applications. This was achieved by increasing the cutoff wavelength lambda sub c to 1630 nm and reducing delta to 0.75% to be comparable with the largest delta reported for a pure-silica core fiber. The bending losses in both fibers also are much less than a telco fiber with delta = 0.34% and lambda sub c = 1200 nm. The high lambda sub c in the dual-mode fiber has the same effect of confining the mode field tightly to the core and reducing bending losses as the high delta in the high-delta fiber.
