An optimum fiber structure for a practical dispersion-compensating fiber (DCF) has been explored theoretically and experimentally, taking dispersion, attenuation, bending loss characteristics, polarization mode dispersion, and nonlinear effects into

Accelerated tests of Er-doped fibers in hydrogen environments are carried out and as the evidence of their long-term utilization, the degradations in loss and gain are estimated. The hydrogen-induced loss-increase in Er-doped fibers with 0 to 3 perce

DCF for SSMF with record high figure-of-merit of 450ps/nm/dB and low residual dispersion within ±0.08ps/nm/km in C-band is fabricated after appropriately designed profile. Its DCF module for 80km-long SSMF realizes low insertion loss of 3.6dB.

High accuracy x-rays measurements confirmed that the average structure of BaMnF4 in the incommensurate phase is monoclinic. Also the results of accurate measurements of the lattice strains of BaMnF4 are reported. It is conspicuous that there is sligh

The temperature dependence of chromatic dispersion is examined for various types of fiber. Its coefficient is found to depend strongly on the dispersion slope. Dispersion-flattened fiber has a significantly low coefficient of -0.0005(ps/nm/km)/ degre

Third-order cascaded Raman amplification is demonstrated for the first time and shown to provide a 2.5-dB improvement in receiver sensitivity over conventional pumping. A dual-wavelength third-order pumping scheme requiring only one active source is
