BlueOptics kuituoptinen vaimennin Singlemode ST Simplex 7dB ( SFA23BK7 )

Optimal Fiber ConnectionsBlueOptics© SFA23BK7 7dB Fiber Optic Attenuator for single-mode (9/125µm) fiber links G.652.D (from 1270nm to 1610nm) from CBO, with ST/PC Simplex connector and highly reliable ceramic ferrule. The attenuation of optical fibers refers to the loss of energy of the light beam, which occurs when passing through a fiber in form of absorption and scattering. In order to reduce the signal level on a glass fiber line fiber attenuators are used to increase the damping. Mainly on short distances the installation of an attenuator may be necessary, so the high transmission power does not override the recipient.Best Attenuation ValuesAll BlueOptics SFA23BK7 7dB ST/PC Fiber Optic Attenuators have a low input loss and a high return loss. Further optimization of the return loss by adjusting the polish (PC or 8°APC) is possible. By default BlueOptics SFA23BK7 7dB ST/PC Fiber Optic Attenuators are available in the attenuation stages 1, 2, 3, 5, 7, 10, 15, 20, 25 and 30dB and are designed for working in temperature ranges from -40°C to +75°C.Highest Quality ComponentsFor lossless transmissions exclusively branded fibers from well-known manufacturers such as Corning, Fujikura or YOFC are used in the production process of BlueOptics SFA23BK7 7dB ST/PC Fiber Attenuators. All installed connectors are manufactured by brand manufacturers such as Amphenol, Diamond, Nissin Kasei or Reichle & De-Massari with highly reliable BlueOptics Zirconia ceramic ferrule and achieve a lifetime of up to 1500 mating cycles.Error-free TransmissionBlueOptics SFA23BK7 7dB ST/PC Fiber Attenuators are tested after production with interferometer and Optical-Time-Domain-Reflectometry (OTDR) to ensure the best quality. A measurement protocol of the input loss and return loss values is included with every shipped BlueOptics SFA23BK7 7dB ST/PC Fiber Attenuator.BlueOptics SFA23BK7 7dB ST/PC Fiber Attenuators meet the Telcordia Requirements GR-326-Core 4.4.Industrial StandardsBlueOptics SFA23BK7 7dB ST/PC Fiber Attenuator are manufactured to meet generally accepted industry standards and norms and are equipped with a flame-retardant LSZH jacket. In case of a fire thus creates a very low smoke emission in comparison to PVC coated Fiber Attenuators. Furthermore no halogen is released.BlueOptics SFA23BK7 7dB ST/PC Fiber Attenuators meet the following Norms: IEC-61034, IEC-754-1, IEC 60332-1, IEC 60332-3, IEC/EN 60950 and RoHS.BlueOptics SFA23BK7.
