RSS fibersClassification of Two-Link Failures for All-Optical Networks
White Paper Generally, the failure of a link entails the failure of all fibers traversing that link, and algorithms for recovery must not assume that some part of the link remains intact. As all-optical networking becomes feasible, a need arises to understand... [18 Jul 2008]
Optical Switching Middleware for the OptIPuter
White Paper However, this time the parallelism is in multiple wavelengths of light, or lambdas, on single optical fibers, creating a LambdaGrid. The OptIPuter is a radical distributed visualization, teleimmersion, data mining and computing architecture. [18 Jul 2008]
The Problem of Upstream Traffic Synchronization in Passive Optical Networks
White Paper Because distance from central office to every network unit is different, if every unit will transmit in its own time slot, due to differences in propagation delays, data will collide in the point where fibers from different network units join... [18 Jul 2008]
A Dynamic Load Balancing in Wireless CDMA Cellular Networks
White Paper The CDMA techniques enables a base tranciever station to connect microcells with optical fibers and to control the channels by sectorizing the microcells. With the increase of cellular users the traffic hot spots and unbalanced call distributions... [10 Jul 2008]
Orthogonal Frequency-Division Multiplexing in Wireless Communication Systems With Multimode Fiber Feeds
White Paper The performance of coded orthogonal frequency-division multiplexing (OFDM) for a variety of multimode fiber profiles, including stepped index and á-profile graded index fibers, is assessed. The feasibility of using multimode fiber as an inexpensive... [03 Jul 2008]
Comparing Metro WDM Systems: Unidirectional vs. Bidirectional Implementations
White Paper One easy feature to be seen as a difference among the broad offer of Metro WDM products is the minimum number of fibers required for system operation. For most WDM products, a fiber pair is required to achieve full duplex interconnection between... [03 Jul 2008]
Design and Manufacture of Dispersion Compensating Fibers and Their Performance in Systems
White Paper This talk will address recent advances in single-mode dispersion compensating fibers. While discrete module applications will be addressed, the emphasis will be on fibers for cabled application and their performance in systems. [03 Jul 2008]
Laser Optimized Multimode Fibers for Short Reach 10 Gbps Systems
White Paper Increasing bandwidth demands are driving the need for low cost 10 Gigabit per second (Gbps) connectivity in Local Area Networks, Storage Area Networks, and Central Offices. Multimode fiber systems have traditionally provided the lowest cost for... [03 Jul 2008]
Mixing TrueWave RS Fiber with Other Single-Mode Fibers in a Network
White Paper A variety of single-mode fiber types can be found in today’s installed networks. Standards bodies, such as the IEC and ITU, recognize four categories of single-mode fiber: dispersionunshifted (G.652), dispersion-shifted (G.653), cutoff-shifted... [03 Jul 2008]
Dispersion Compensating Fibers for Non-zero Dispersion Fibers
White Paper Single mode dispersion compensating fibers capable of compensating dispersion and dispersion slope of high slope NZDF with relative dispersion slopes up to 0.018 nm-1 are presented. Furthermore the importance of matching the dispersion curvature is... [03 Jul 2008]
Polarization Mode Dispersion
White Paper Polarization mode dispersion arises in single-mode fibers when the fibers are not cylindrically symmetrical. This asymmetry causes the two polarization modes, which ideally propagate in unison, to propagate at slightly different velocities. [03 Jul 2008]
A Novel 240-Gbps Channel-By-Channel Dedicated Optical Protection Ring Network Using Wavelength Selective Switches
White Paper In this paper, we present novel concepts of DWDM system designs that handle plural wavelengths in single fibers with capability of OADM and protection switching. A novel optical add-drop multiplex (OADM) node architecture design using wavelength... [03 Jul 2008]
Fiber Optic Cable in Wet Environments
White Paper The question of how adequately a fiber optic breakout cable will protect the optical fibers within it from the potentially degrading effects of water and free OH- ions often comes up in the design of fiber optic transmission systems. [03 Jul 2008]
What's in a Twist? Helically Stranded
White Paper Since the dawn of man’s interest in combining filaments, strands, fibers or other elements into thread, yarn, cords, ropes or lines, these elements have always been twisted together. More recently, virtually all wire ropes (electrical conductors... [03 Jul 2008]
Applications of Switch Matrices in Metro Optical Networking
White Paper These functionalities can be provided by optical switching matrices that switch either fibers, groups of wavelengths, or single wavelengths. Transparent optical networks are replacing SDH / SONET in metropolitan and regional areas. [03 Jul 2008]
