We evaluate numerically and experimentally the stimulated Brillouin scattering (SBS) threshold increase for a short, highly nonlinear GeO/sub 2/-doped fiber by applying different temperature distributions along the fiber. The temperature coefficient

The basic principles for use of dispersion compensating fibers (DCF) are reviewed, including definition of figure of merit and condition for dispersion slope compensation. The main design features of a triple-cladding index profile design are examine

In this letter, we report on up to 300-Gb/s real-time all-fiber-based optical eye-diagram measurements with 1.6-ps temporal resolution and 5-Hz refresh rate by all-optical sampling using parametric amplification in a short (50 m) highly nonlinear fib

Broad-band and pulsewidth maintained wavelength conversion based on a nonlinear optical loop mirror (NOLM) consisting of 1-km high-nonlinearity dispersion-shifted fiber (HNL-DSF) is realized in the whole C-band. Because only 1-km HNL-DSF fiber issued

We demonstrate 1.6 Tb/s (40 /spl times/ 42.7 Gb/s) WDM transmission over 2000 km of fiber with 100-km amplifier spacing and 100-GHZ channel spacing. Error free transmission of all 40 C-band channels is achieved. We employ dispersion-managed fiber spa

Single-mode dispersion compensating fibers for discrete module applications are still the best choice for broadband dispersion compensation. Improvements in slope matching and insertion loss are being made continually. Cabled dispersion compensating

The negative dispersion slope of dispersion-compensating fibers has been optimized by increasing the width of the depressed cladding. Simultaneous compensation and dispersion slope has been demonstrated on an actual link.

We demonstrate a transparent CW-pumped highly nonlinear fiber wavelength converter with a conversion bandwidth of 61 nm and a pump wavelength tuning range of 24 nm. The conversion quality is confirmed by bit-error rate measurements showing less than

A spectral efficiency of 0.53 b/s/Hz is demonstrated at 160 Gb/s over 400 km. The pseudo-linear transmission regime with 100% post compensation is used, and the transmission loss through the 100 km spans is compensated with distributed Raman amplific

Dispersion compensating fiber (DCF) is a mature and widely used technology for dispersion compensation. For future ultra-high-capacity systems where dispersion slope compensation is inevitable, DCFs based on standard single-mode operation has been de
