Numerical Aperture 0.09; Core Dia. 20 µm; Cladding Dia. 127 µm; Gray Loss <20 dB/km; Polarization Extinction Ratio >20 dBGreitlex Photonics’ SBS-DC series of SBS-suppressed optical fibers feature a suppressed stimulated Brillouin scattering gain. Stimulated Brillouin scattering (SBS) is the major factor limiting maximal power of narrow-band fiber lasers (less than 100 MHz linewidth). It is especially crucial in applications which require small mode field diameter (MFD), i.e. Raman amplifiers. Suppression of SBS gain, while maintaining MFD (and Raman gain) becomes a very important task in such fibers. Another promising application of single-frequency lasers is LIDAR (Light Detection And Ranging). In the case of all-fiber systems, it is the passive fibers at the amplifier output (pigtails of isolators, circulators, collimators) that limit the maximum achievable peak power. Thus, development of large mode area (LMA) passive fibers with increased SBS threshold (as compared to standard LMA fibers) is more and more critical for those applications. To suppress SBS gain for a fixed MFD, Greitlex Photonics uses a specially designed multi-layer, multi-components doped core. It allows to suppress SBS gain by 3 to 5 dB relative to standard, uniformly doped Ge-doped passive fibers with the same MFD. The developed method allows Greitlex Photonics to design custom dopants distribution over the core to suppress SBS by 3 to 5 dB for most of the actual optical refractive index profiles (any core numerical aperture and diameter). The SBS-DC-20/125-1550PM polarization maintaining (PM) fiber has been specially designed to be used in pigtails of output components (isolators, collimators, pump-and-signal combiners etc.) of high peak-power single-frequency lasers operated near 1550 nm. The fiber is intended for utilization in systems with the ability to maintain polarization. Fibers with suppressed SBS-gain for a custom designed operating wavelength, core numerical aperture (NA) and diameter are available on request. Please contact AMS Technologies to discuss your customized SBS-suppressed optical fiber solution.

35 to 450 A RMS; Single Terminal; 28 to 45 kV; Mechanical Life 0.5 to 2 Mio. OperationsJennings Technology’s series of vacuum interrupters handle a wide range of voltage and current interrupt levels, and high-quality and highly reliable interrupters are available for the utility and industrial markets.Current interruption in a vacuum is recognized as the ideal switching technology in the medium voltage range, and it is also applied in high-voltage and low-voltage applications. Excellent switching capabilities and compact design make vacuum interrupters the most economical switching device solutions possible.Jennings vacuum interrupters feature an evacuated ceramic insulating envelope surrounding two contacts, one fixed and one movable. The movable contact is operated from the outside through a metallic bellows. Contacts are typically a copper alloy that is developed for use in AC voltage applications. The end plates are made of stainless steel or copper.With these features, vacuum interrupters can be expected to last the life of the equipment in which they are installed. Their interruption mechanism is independent of the current magnitude, so interruption can normally be anticipated at the first current zero with no restriking, as the dielectric strength of the contact gap recovers more rapidly than the recovery voltage can rise.Vacuum dielectric enables the interrupters’ contacts to be arranged close together, so circuit interruptions can be designed in a smaller envelope. With current interruption occurring in a vacuum, all arcing is confined within the vacuum interrupter body, so Jennings interrupters are noise-free and flash-free, avoid contact contamination as oxides and corrosion layers cannot form in vacuum, and they do not emit any greenhouse or toxic gases.Key Features: Long Life, High Reliability Controlled Contact Erosion Results in Virtually Maintenance-free Operation Fast Interrupting Speed Rapid Dielectric Recovery High Cycle Withstand Voltages Robust, Compact Design Environmentally Friendly Atmospheric Contact Contamination is Eliminated Noise-free and Flash-free Applications: Load Break Switches; Contactors for Industrial and Motor Control; Capacitor Bank Switching; Circuit Breakers; Specialty RF and DC Applications
