Specifications of German Well Logging Optical Cables
The range of cables for direct buried installation includes all our four basic designs: concentric core, grooved core tape, DryTech and tape in loose tubes. Suitable for oil wells, gas wells, coal mines or under high temperature conditions. The cables marked with Dry; They are a series of cables in which the typical water blocking the intermediate tubes (gelatin, water swelling tape or powder) is replaced with a solid foamed thermoplastic elastomer. Permanent downhole fiber-optic cables are critical infrastructure in wellbore monitoring systems, ensuring reliable transmission of data for applications such as distributed temperature, acoustic, and strain sensing (DTS, DAS, and DSS)—all with one 1/4-in control line. In many applications, the optical fiber must be contained within a cable structure to ensure it survives the environment in which it is designed to be deployed. The FIMT can contain a range of fibers, both single mode (SMF) and multi mode (MMF). The fiber selection and appropriate filling gels can be customized to meet the customers specifications / requirements.
