Abstract:

In order to avoid the use of pressurized in optical fiber cables, a filled, water-blocking optical fiber cable was developed. It consists of a stacked-ribbon core surrounded by a crossply-reinforced sheath. The ribbon core is filled with a newly formulated filling compound which remains very soft at temperatures as low as -40 degrees F yet retains anti-slump properties at high temperatures. Cables were made and tested for cabling added loss and for environmentally induced added loss in a thermal cycling mode from - 40 degrees F to 190 degrees F. Mechanical tests were performed to ascertain the resistance of the cables to damage from impact, bending, and twisting. In every manner, the cables performed on a par with equivalent aircore cables with cabling added loss typically 0.1 dBkm. Also, pneumatic-resistance tests proved the water-blocking capability of the filling. Author
