James Webb Space Telescope (JWST) Spacewire Reduced Cost of Ownership, Easy Integration, and HighPerformance for Flight and Lab Grade Cable Assemblies. The success of any space mission begins with reliable data transmission and Glenair Spacewire cables, built to meet the strict standards set forth by ECSS-E-ST-50-12C, make this a reality. Our Spacewire cables offer bidirectional, high speed data transmission rates up to 400 Mbits/s while significantly reducing cross talk, skew, and signal attenuation. By incorporating a serial, point-to-point cable, with low voltage differential signaling (LVDS) reduced costs are realized through an easily integrated data transmission cable. These features allow Spacewire cables to be incorporated across various satellite programs without the expense of costly design customization. Spacewire: The Space Industry Data Transmission Standard Glenair Spacewire assemblies begin with a high performance cable built with expanded polytetraflouroethylene (ePTFE) insulation. This material allows for low-loss transmission of LVDS signals maximizing data-rates while allowing for the implementation of standard hardware protocols, thus eliminating the need for design customization and long lead time cable projects. Typical Uses Include Approved for Use by: • EGSE applications • Radar sensor systems • Hi-resolution camera equipment • Sensor, mass-memory unit, and telemetry subsystem interconnections • ESA • NASA • JAXA • RKA Connector/Cable Laboratory and Space Grade Versions Available Qualified MIL-DTL-83513 Micro-D Connector Gold Plated Copper Alloy TwistPin Contacts Basic Cable, 4 Twisted Pair Cables and a Ground Epoxy Resin Potting EMI Banding Backshell Performance 3 Amps Temperature Tolerance -200 to 180° C 100 Ω Impedance Shielded Signal Pair Very Low Skew, Signal Attenuation and Cross Talk 65dB Minimum Attenuation Shielding Effectiveness Low Magnetic Permeability IAW EIA-364-54 For more information contact Glenair at 818-247-6000 or visit our website at www.glenair.com Spacewire T E C H N I C A L S P E C I F I C AT I O N S Notes: Diagram (P) Diagram (GP) Shells/backshells - aluminum alloy/electroless nickel Insulators - high grade rigid dielectric/N.A.
