VFT Fiber Vacuum Pressure Feedthroughs

Viscosity 70->20,000 mPas; Shear Bond Strength > 69->200 kgf/cm²; Bending Adhesion Strength 9-25 kgf/cm²; UV Curing Conditions 10-100 mW/cm², 5, 10 min; Colour Light Yellow, Colourless, White; Tg +42-+219 °C NTT-AT’s series of adhesives for fiber array assemblies feature high moisture resistance and excellent workability for v-groove fixing or optical fiber fixing. Fiber arrays are used for the input and output of optical waveguide devices. NTT-AT’s AT3925M, AT9390, AT9968, AT3727E and AT3728E epoxy-based optical adhesives are used for fixing the v-grooves and have realized price reductions while enhancing moisture resistance compared to conventional products. These adhesives can be polished after assembly. NTT-AT’s AT9575M (epoxy) and AT8105 (acrylate) adhesives for optical fiber fixing have gained popularity for their good workability as non-fluid adhesives. NTT-AT has executed durability tests that have shown no peeling of a fiber array after 2,000 hours at +85 °C and 85% of humidity. With viscosities that are appropriate for the usage location, the adhesives for fiber array assemblies are easy to use. While the adhesives for fixing v-grooves show fluidity, the optical fiber fixing adhesives’ consistency is that of a paste, suitable for protecting the fiber.

1100-1600 nm; Responsivity 0.8 A/W; Capacitance 0.25 pF; Dark Current 0.1 nA; Package 3-pin TO 46, 6-pin TO-8, 10-pin Mini-Flat Wooriro’s SPAD series (Single Photon Avalanche Diode) comprises InGaAs/InP APD devices specially designed and fabricated for the use of single photon avalanche detection (SPAD) with internal or external cooling systems. SPAD avalanche photodiodes (APDs) can be operated at the voltage above breakdown for short periods, this mode of operation is called “Geiger mode” or “Gated mode” operation. Ultra-low noise operation is possible at a case temperature of -40 °C. The devices can be used for quantum key distribution (QKD) receivers. SPAD devices are available without an integrated thermoelectric cooling device (TEC) in a 3-pin TO-46 package or with integrated TEC in a 6-pin TO-8 package as well as in a butterfly-style 10-pin Mini-Flat package.
