Typical Wrapping Tube Cable Structure

The Spider web ribbon is wrapped with a water-blocking-tape. The water blocking tape can easily be taken away, and operator can get access to fibers easily.

Wrapping tube is a simple technology of wrapping water blocking tape around a group of SWR bundles

Technology Underlying 5 Features

Spider Web Ribbon (SWR), the core technology of WTC

An image of spider web ribbon, which consists of 12 single fibers, and the fibers are intermittently bonded to form ribbon structure.

SWR is an intermittently bonded ribbon and realizes,

  • Mass fusion splice
  • High packaging density
