Optical Fiber Buffer for High‐Performance Broadband Switching
European Transactions on Telecommunications, 1993AbstractThis paper presents an optical buffer shift register based on a set of fiber delay lines electrically‐controlled, to provide cell storage and queueing capabilities in high‐performance broadband switches satisfying ATM service requirements. The concept of multi‐wavelength cell buffering is adopted, to realise a partially shared buffer with a ...

Fiber optic loop buffer switch incorporating 3R regeneration
Optical and Quantum Electronics, 2011In this paper, an all-optical regenerator based, photonic packet switch architecture, which consists of fiber loop for the storage of the contending packets, is proposed. In the loop buffer, the available buffer space may not be fully utilized due to the re-circulation limit (maximum number of re-circulations that data can take before it can be ...

Constructing optical buffers with switches and fiber delay lines
2009 15th Asia-Pacific Conference on Communications, 2009Designing optical buffer is still challenge for supporting all optical packet switching. The current practice is to emulate the optical buffer functions through a combination of switch and fiber delay lines (SDL). In this paper we introduce the recent progress on this line, in particular, the SDL-based emulation of optical queues, connectors and ...

Development of optical indoor cables using 0.9-mm tight-buffered optical fiber
2009 14th OptoElectronics and Communications Conference, 2009We propose optical indoor cables using 0.9-mm tight-buffered optical fiber, placing importance on handling performance and ease of work. This MM fiber-based cable allows 10-Gbps transmission for up to 600 m.

Wavelength dependence of bending loss in monomode optical fibers: effect of the fiber buffer coating
Optics Letters, 1990The bend-induced optical loss in a monomode fiber has been studied as a continuous function of wavelength in the range 1.2-1.6 microm. The loss was observed to be an oscillatory function of wavelength. These observations were explained by using a model based on interference between the guided core mode in the fiber and a "whispering gallery" mode ...

Fast curing primary buffer coatings for high strength optical fibers
Journal of Lightwave Technology, 1986UV-curable polyetherurethane acrylates and poly- (dimethyl-co-methylphenyl siloxane) acrylates have been investigated for the primary buffer coating of optical fibers. Curing behavior, Emodulus, glass transition temperature and refractive index have been studied in relation to the molecular structure of both acrylate types.

Fiber delay lines optical buffer for ATM photonic switching applications
IEEE INFOCOM '93 The Conference on Computer Communications, Proceedings, 2002An optical buffer shift register based on a set of fiber delay lines is presented, with the goal of providing cell storage and queuing in asynchronous transfer mode (ATM) photonic switches. The concept of multiwavelength cell buffering is adopted, to realize a shared buffer with a storage capacity equivalent to a set of shift registers.

Shared fiber delay line buffers in asynchronous optical packet switches
IEEE Journal on Selected Areas in Communications, 2006Packet contention is a major issue in asynchronous optical packet switching networks. Optical buffering, which is implemented by fiber delay lines (FDLs), is fundamental to many optical switch implementations for resolving contention. Most existing optical buffering implementations are output-based and require a huge amount of FDLs as well as larger ...

Efficient Designs of Optical LIFO Buffer with Switches and Fiber Delay Lines
IEEE Transactions on Communications, 2011The lack of optical buffer is still one of the main problems that hinder the development of all optical networks. Current works on this topic mainly focus on the emulation of optical buffers based on a combination of fiber delay line (FDL) and switch. These works have demonstrated the feasibility of FDL-based emulation for many kinds of optical buffers,
