Aerospace IEEE1394b Cable

  • Aerospace IEEE1394b Cable

    Overview

    LINCOS 1394B Cable provides high fidelity signal links for interconnect solutions up to 23m at S400 data rate, the cable can support higher 1394 data rates. Quad design offers significant size and weight savings when compared with conventional  constructions such as twisted pair cables. In addition, the combination of materials in this construction supports a wide temperature range and meets the most demanding aerospace environments.This design provide greater flexibility and easy of installation in  challenging environments. It suits military airframe and spaceflight applications.

    Features and benifits

    > Quad design is approximately 40% smaller than common dual twisted pair constructions

    >Highly uniform PTFE dielectric materials with ultra low loss tangent

    >Dielectric offers best compromise between low dielectric constant for small size and firm outer layer to prevent pushback during termination

    >Available in AWG 28 to 22 sizes

    Cable Property

    > Meet IEEE1394b cable specification
    > Provide high fidelity signal link for interconnect
    > Low attenuation to support longer distance connecting
    > Signal integrity with stable performance in extreme conditions,temperatures ranging from -55ºC ~ 200ºC
    > Significantly reduce weight while maintaining reliable signal integrity.
    > Small diameter increases flexibility with tight bend radius, improved installation, high-density cable bundles, easy routing in confined space

    Eye Patten test

    PRBS Pattern.png

    Eye Pattern test of 50 ft of cable transmitting 500 Mbps of data. The diamond shaped Eye Mask  indicates the minimum receiver sensitivity as 

    specified by IEEE 1394b-2002. The Eye Mask 

    test passes with margin indicating greater

     length transmission is possible with this cable.





    Attenuation

    Below figure is attenuation traces of LINCOS product with different conductor size with 110 ohms quad cable and same length which is 50 ft.
