The impact of different detection schemes on the performance of Brillouin optical timedomain analysis is investigated theoretically and experimentally. The study provides guidance for the optimization of BOTDA sensors depending on the targeted range.

A novel, spectrally-efficient modulation scheme, code-cycle modulation (CCM), that permits a threefold increase in the number of active users is presented along with a supporting receiver architecture. ©2005 Optical Society of America OCIS codes: (060.2330) Fiber optics communication, (060.2360) Fiber optics links and subsystems

We evaluate the benefit of reconfiguration after single-link failures in supporting recovery from additional failures. We also develop an intuitive classification of two-link failures to help understand the impact of failures. c 2003 Optical Society of America OCIS codes: (060.4250) Fiber optics and optical communications/networks; (060.4510) Fiber optics and optical communications/optical comm...

Requirements are identified for an open-system approach to integrated IP-over-optical networks. Using DWDM XENPAK interfaces with integrated G.709 framing we demonstrate error-free connectivity of core IP routers across a 574km link. © 2007 Optical Society of America OCIS codes: (060.2330) Fiber optics communications, (060.2340) Fiber optics components

The use of fiber optics in local area networks (LANs), such as Ethernet, has increased due to the inherent advantages of using fiber. High data rates can be maintained without electromagnetic or radio frequency interference (EMI/RFI). Longer distances can be achieved over that of copper wiring. For the industrial/commercial user, fiber offers high-voltage isolation, intrinsic safety and elimina...

In the present work we explore an approximate solution of the Navier-Stokes equations for optical fiber coating in a pressure type die by withdrawal from a bath of two immiscible Oldroyd 8-conatant fluid under constant pressure gradient in the axial direction using two-layer coating flow. The constitutive equation of motion has been solved by using optimal homotopy asymptotic method (OHAM) for ...
