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 …

In this paper, we present the experimental result for the fiber optic frequency transfer link
with optical regenerators exploiting the same Er-doped fiber for amplifying the signals in …

(57) ABSTRACT A transmissive active channel element is provided in each signal channel
of a monolithic multi-channel TXPIC Where each channel also includes a modulated source …

A bidirectional transmission system with 16 10-Gb/s dense wavelength-division-multiplexing
channels on 32 wavelengths is demonstrated over 5000 km (50/spl times/100 km) of …

This paper introduces an Erbium-doped fiber amplifier (EDFA)-based solution to support the
maximum link budget class (E2) of the time-and wavelength-division multiplexed passive …

We propose and demonstrate, for the first time, a bidirectional hybrid dense wavelength-
division-multiplexing (DWDM) system for CATV and OC-48 trunking with two wavelengths …

We present an angle-tuned Fabry-Perot etalon filter that has periodic Gaussian
transmittance curves down to 40 dB from peak transmissions in spectral domain. This …

We propose a cost-effective bidirectional optical amplifier consisting of a single
unidirectional Er-doped fiber amplifier and a fiber Mach-Zehnder interferometer (MZI). We …

A bidirectional add/drop optical amplifier used in wavelength division multiplexing (WDM)
optical networks to suppress the power change resulting from the adding and dropping of …

A bidirectional amplification module has been proposed for use in IP-over-CWDM networks.
The module is based on a bidirectional erbium-doped fiber amplifier. The loss compensation …
