Dual-Link Failure Resiliency Through Backup Link Mutual Exclusion

Abstract”
Networks employ page link protection to achieve fast recovery. While the first page link failure can be protected using page link protection, there are several alternatives for protecting against the second failure. This paper formally classifies the approaches to dual-link failure resiliency. One of the strategies to recover from dual-link failures is to employ page link protection for the two failed links independently, which requires that two links may ....etc

Optical Free Space Communication

With the improvements in semiconductors optical free space communication has become n attractive alternative to existing signal conducts as fibre or wireless (RF). It offers high data rates and is much less expensive than underground fibre. But there are a few restrictions, which may mean it remains an alternative. Many engineers are familiar with one of two successful existing technologies for data communication:

(1) Guided wave (e.g. fibre optics) and
(2) w ....etc

In summer 1977, ESA placed the first technological study contract in the domain of intersatellite optical links. Now, twenty years later, a major milestone has been reached with the SILEX laser terminals having been flight tested for integration with their host spacecraft. At the same time, ESA is preparing itself for a new challenge: the potential massive use of optical cross links in satellite constellations for mobile communications and global multimedia services. This is an opportune moment to look back at the past twenty years of ESA effor ....etc

A bidirectional page link using optical circulators



Introduction
The standard fiber cables in use today, shows variations in the attenuation characteristics. The minimum attenuation occurs at wavelengths around 1310 nm and 1550 nm. Any one of the above wavelengths is used for transmitting the signal using the laser diodes through the optical fiber. While constructing the bidirectional link, any one of the above wavelengths is considered and used for the bid ....etc

Single-link failure detection in all-optical networks using monitoring cycles and paths

In this paper, we consider the problem of fault localization in all-optical networks. We introduce the concept of monitoring cycles (MCs) and monitoring paths (MPs) for unique identification of single-link failures. MCs and MPs are required to pass through one or more monitoring locations. They are constructed such that any single-link failure results in the failure of a unique combination of MCs and MPs that pass through the monitoring location(s). For ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc
