AGY Launches Low-Loss Glass Fibre Yarn AGY has introduced L-Glass, a low-loss glass fibre yarn for printed wiring board (PWB) applications. The low dielectric constant (Dk) and low dissipation factor (Df) properties of L-Glass fibre are suitable for designs requiring increased signal speeds and better signal integrity than traditional E-Glass/epoxy substrate materials. Scott Northrup, director of new business development at AGY, said: 'Substrate materials that provide low dielectric constant and low dissipation factor properties have become an essential element of high-speed digital systems such as mobile communication base stations, high-end routers and servers, and high-speed storage networks. 'As these systems move to higher processing speeds, substrates with low-loss properties are needed to ensure the speed and integrity of the signals,' he added. Low-loss laminates for high-speed applications have traditionally been produced in one of two ways. In one method, a ...

Lambda Unveils Fibre-To-Fibre Optical Isolators Lambda Photometrics has announced a line of fibre-to-fibre optical isolators from Optics for Research (OFR). They are designed for use in super-luminescent light-emitting diode (SLED or SLD) applications. These isolators provide high isolation and low insertion loss over broad bandwidths and are available for common SLED wavelength ranges in the 750nm to 900nm region. These isolators use OFR's proven IO-F series optical engine, and two platforms are available for single- or dual-chip SLED requirements. For single-chip SLED applications, the IO-F-SL1 fibre isolator provides high performance over a spectral bandwidth of 70nm. For dual-chip SLED systems, the IO-F-BB-SL2 provides coverage over a 100nm bandwidth. Isolation at the centre wavelength typically exceeds 35dB, and is maintained to at least 20dB at the bandwidth FWHM points for both models. Optical power handling capability is 3W in the forward and reverse directions, and t...
