SEPIGEL H 200 LWT
Ultimate signal and transmission protection
Ultimate signal and transmission protection
Chemical and mechanical protection to improve lifetime and reliability of the optic fiber.
Fluid under stress for convenient manufacturing conditions:
- Easy to pump at room temperature.
- Easy to inject into the cable.
Viscous at rest:
- As soon as the filling gel is introduced into the cable, it regains its viscosity.
- Provides mechanical protection to the fiber optic cable.

At high shear rate, when stress is applied to the gel, it is fluid. Therefore the SEPIGELTM H 200 LWT is easy to pump during the manufacturing of the cable.
SEPIGELTM H 200 LWT is viscous at rest to provide mechanical protection to the optical fiber but still allows a bit of movement.
Total hydrogen adsorption of 1 gram of SEPIGELTM H 200 LWT is between 3.5 to 4 cm3 in experimental conditions. Those are indicative values which can slightly differ according to experimental devices, amount of sample in the device and surface state of the sample. However they clearly show the high hydrogen adsorption capacity of the SEPIGELTM H 200 LWT.
It has an immediate capacity of adsorption of hydrogen to protect the fiber from the hydrogen generated during manufacturing. The filling gel SEPIGELTM H 200 LWT also has a continuous capacity of hydrogen scavenging to protect the fiber during the cable’s lifetime.
