FBG (FIBER BRAGG GRATING) UNTUK DWDM (DENSE WAVELENGTH DIVISION MULTIPLEXING)

Dense Wavelength Division Multiplexing (DWDM) and the Dickson Grating

Dec 2000 News: * Claiming a world-best speed record for optical data transmission, researchers at Siemens have transmitted 7 Tbits/s over a single optical fiber using DWDM. That's the equivalent of over 100 million telephone calls or a billion pages of typed data per second. The demonstration was conducted by Siemens' Information and Communication Networks Group at the company's Advanced Optica...

Optical Add-Drop Multiplexer Based on Fiber Bragg Gratings for Dense Wavelength Division Multiplexing Networks

A configurable optical add-drop multiplexer (OADM) based on fibre Bragg gratings is reported. Dynamically selection of the add-drop or pass-through functionality is realised according to the control of an optical switch. The OADM performance measurement realised in a 70 km, 3 × 2.5 Gb/s channels dense wavelength division multiplexing (DWDM) experimental network are reported and the results comp...

Wavelength-division and spatial multiplexing using tandem interferometers for Bragg grating sensor networks.

We present a new method for the interrogation of large arrays of Bragg grating sensors. Eight gratings operating between the wavelengths of 1533 and 1555 nm have been demultiplexed. An unbalanced Mach– Zehnder interferometer illuminated by a single low-coherence source provides a high-phase-resolution output for each sensor, the outputs of which are sequentially selected in wavelength by a tuna...
