Raman amplifiers are being deployed in almost every new long-haul and ultralong-haul
fiber-optic transmission systems, making them one of the first widely commercialized …

This paper reviews recent progress in broad-band Raman amplifiers for wavelength-division-
multiplexed (WDM) applications. After the fundamentals of Raman amplifiers are discussed …

Fiber-optic multi-band transmission (MBT) aims at exploiting the low-loss spectral windows
of single-mode fibers (SMFs) for data transport, expanding by the available bandwidth of C …

We describe a method to estimate the capacity limit of fiber-optic communication systems
(or¿ fiber channels¿) based on information theory. This paper is divided into two parts. Part 1 …

Raman amplification has enabled dramatic increases in the reach and capacity of lightwave
systems. This tutorial explains why, starting with the fundamental properties of gain from …

Bismuth-doped fibre amplifiers offer an attractive solution for expanding the bandwidth of
fibre-optic telecommunication systems beyond the current C-band (1530-1565 nm). We …

This paper reviews properties and use of conventional single-mode dispersion-
compensating fibers (DCFs). The quality of the dispersion compensation expressed as …

We investigate new connection-provisioning algorithms to efficiently provide signal-quality-
guaranteed connections in an optical wavelength-division-multiplexing (WDM) mesh …

We demonstrate a single-shot digitizer with a 10 Tsample∕ s sampling rate. This feat is
accomplished with a photonic time stretch preprocessor that slows down the electrical …

Raman amplification has been commercially utilized in optical transmission systems for
more than a decade. The drive toward higher spectral density has increased the interest in …
