Abstract:
1. A connection structure for a dispersion compensating optical fiber obtained by fusion-splicing a dispersion compensating optical fiber having a negative dispersion slope with a connection optical fiber having a different near field pattern from that of the dispersion compensating optical fiber, wherein an effective core area of the connection optical fiber ranges from about 1 to about 35 μm 2 greater than an effective core area of the dispersion compensating optical fiber, and wherein said connection optical fiber has a near field pattern so that, at an operational wavelength, a theoretical joint loss calculated from an overlap integral of a simulated near field pattern of said dispersion compensating optical fiber measured by simulating fusion splicing and a simulated near field pattern of said connection optical fiber measured by simulating fusion splicing is 0.3 dB or less.
