A terabyte is a lot of data... but data needs are growing. Many corporations have a need for high-speed networks, and even with the best of broadband, you can get a respectable 150 megabits a second which is much faster than your typical consumer cable connection. Download times are...
The marketplace is currently on the cusp of the mass deployment of fiber-based broadband access directly to individual residences. Optical access networks take a variety of forms that will extend optical fibers all the way to or near the residence. Architectures known as Passive Optical Networks PONs are likely to...
Gigabit PON is an attractive FTTH broadband access network technology because it meets the needs of carrier's world-wide. GE-PON has successfully demonstrated this approach and is being deployed in high volume in Asia, while the GPON standard will provide similar capabilities for carriers in North America. It includes all of...
BioVigilant has developed an optical technology that can determine the quantity and size of particles in liquid or air, and simultaneously determine whether each particle is inert or biologic, all in real time. The result is that BioVigilant's devices provide instantaneous microbial detection, thereby creating wide-ranging benefits for pharmaceutical manufacturers....
The growing popularity of the Internet is the key driver behind the development of new access methods which would enable a customer to experience a true broadband.

Multi-service transport has successfully integrated new services and new technologies on a common platform. This has enabled operators to extend the working lives of their SONET/SDH networks and capitalize on their existing investment in infrastructure, equipment and operations. Convergent transport is the successor to multi-service transport, bringing yet another level...
The solution proposed in this paper solves the problem of resiliency in the connections between customer sites that span multiple metro Ethernet networks. The solution relies on H-VPLS spoke redundancy. The recovery times associated with the solution are on the same order as those commonly associated with SONET/SDH APS recovery...
Optical fiber sensing is one of today's fastest developing technologies. The significant advantages that optical fiber sensors hold over more conventional sensors for component testing, design validation and structural health monitoring have long been understood. However, it is only within recent years that this unique technology has sufficiently matured to...
This paper focuses on the installation of cable in nuclear power station. Industrial Ethernet applications utilize both copper and fiber optic cable products. However, due to the sensitive environment and EMI, nuclear power plants are specifying fiber optic cable, not necessarily due to its bandwidth, but due to its flexibility,...
This technical white paper explains how the objectives detailed in the accompanying strategy white paper The telecommunications holy grail or a pragmatic means of raising carrier profitability can be achieved using a GMPLS distributed control plane. It first describes the conceptual evolution that, starting from MPLS, led to the integration...
This article discusses the properties of fiber optic sensors that make them suited for applications in the oil sector and introduces the concept of structural health monitoring. Finally, the article discusses the trends in public and governmental safety awareness and environmental protection focus that are set to change the operational...
The assembly within a single optoelectronic interconnect module of different components, including Vertical Cavity Surface Emitting Laser VCSEL and photodiode arrays, optical fibers and electronics implying electrical, optical, mechanical and thermal interactions, introduces new constraints in the conception phase and necessitates a new and different approach for modeling and simulation....
Polymeric optical fiber POF is used for simple light guide and illumination applications. The polymer optical fiber materials can be utilized in flexible lighting elements, which can be combined with textile structures. The POF woven fabrics are introduced as a flexible alternative to lighting elements. This paper discusses various light-emitting...
For almost as long as fiber optic communications has been around, recurrent optimistic predictions have appeared to the effect that soon this communication medium would extend into user premises, both business and residential (FTTB and FTTH, respectively). This white paper reviews these events, technical, economic, regulatory and societal, and comes...
This paper briefly introduces the functional principle of the long-gage sensors used in this application, illustrate their installation and discuss the measurement results obtained during construction. The installed SOFO fiber optic sensors have a measurement basis between 3m and 5m and were installed in pairs in the concrete arch. Measuring...
