Key Features

  • Maintains optical transmission

    Protects the splice without disturbing the fiber's optical transmission properties.

  • Reinforces and protects splice

    Internal steel rod reinforces the fragile fusion point and protects the fiber during installation.

  • One-piece design

    Single integrated sleeve construction simplifies handling — no separate parts to assemble.

  • Hot fusion sealing

    Hot fusion seal tube rebuilds the outer cable coating, protecting the splice against dust and moisture ingress.

  • Cassette compatible

    Fits seamlessly into all euroclust splice protection holders — usable in ec1 and ec2 splice cassettes.

Available Variants

  • 15 length/diameter variants
  • Transparent polyolefin
  • Steel reinforcement rod
  • Red variant (SP/F45/2,5A)
