Abstract
A telecommunications cable includes a distribution cable, a tether branching from the distribution cable at a breakout location, and an enclosure that surrounds the breakout location. The enclosure is secured to the distribution cable at first and second adhesion regions. The enclosure can also secure to the tether at a third adhesion region. The adhesion regions are treated by sanding the regions, cleaning the regions, and then plasma-etching the regions immediately before welding/injection molding the enclosure around the breakout location.
