Bonded Telemetry Pairs
Highest Transmission Stability
Using innovative material technologies, Gore offers bonded telemetry pairs with the highest transmission stability for marine geophysical exploration applications. This results in a smaller outer diameter, enhanced flotation characteristics, and the highest signal intensity under mechanical stress for streamer cables.
Gore’s low dielectric constant, expanded PTFE (ePTFE) and PTFE materials enable the bonding of the pairs. This reduces the overall diameter and weight of the cables. The result is a smaller outer diameter, enhanced floatation characteristics, and the highest signal integrity under mechanical stress for streamer cables. The specific location of each insulated, silver-plated conductor bonded throughout the entire length of the pair maximizes the electrical performance and reliability during flex. Gore uses only the highest quality, multi-layered, concentric, and pin-hole free insulations over each conductor. Each material is compatible with streamer fluids, other floatation media, and can operate in wide temperature ranges.
The data transmission performance of GORE® Bonded Telemetry Pair Cables remains high, consistent, and reliable throughout its life cycle. GORE® Bonded Telemetry Pair Cables have over 10 years of proven performance and unsurpassed reliability in marine streamer cables around the world.
