1km distance for 12.5Gbits

developed V30-850C1SM high-frequency VCSEL (vertical cavity surface emitting laser) used in the tests for datacom applications. The device features up to 2mW optical output power at about 7mW power consumption. The operating voltage is less than 3V. Recent tests produced record low energies expended per bit, approaching 100fJ/bit (femto-Joules per bit). the

VI Systems GmbH (VIS), a supplier of optical engines and components, has demonstrated an optical link operating a serial transmission at a data rate of 12.5 Gbit/s over 1km distance using Draka’s flagship MaxCap-OM4 (50/125 µm) multimode fibre. The tests were carried out at the Technical University of Berlin in Germany, which provided the high speed test bed and scientific support for the measurements. optoelectronic components for use in short reach optical interconnects, VI Systems A specialist in

Identifying defects during production

Beta LaserMike offers its Lump and Neckdown (LN) Detector to wire and cable manufacturers wanting to reliably and accurately identify product faults and surface defects during production. light technology and advanced circuitry to instantly detect changes, such as lumps or neckdowns, in the wire or cable diameter. The signal processing and intelligence is built into the gauge head for a complete, stand-alone detection solution. Outputs can be taken straight from the LN Detector to trigger alarms or to mark devices when faults are detected. The detector is easy to install, set up and operate. It can be used in extrusion, drawing, jacketing and other wire and cable production applications for consistent detection of short-term faults in products. The LN detector is available in a range of models to meet a wide scope of product detection requirements. Depending on the model, the system can detect faults in products with outer diameters ranging from 0.04 to 40mm (0.0015 to 1.60") up to the fastest line speeds. The detector uses infrared

Long-term advantages to manufacturers include increased productivity, reduced production costs and higher quality products. ▲ ▲ The new Lump and Neckdown detector from Beta LaserMike
