Construction method of ground wire of optical distribution box

Construction method of ground wire of optical distribution box

The tube is inserted into a stainless steel, aluminum, or aluminum-coated steel tube, with some slack length of fiber allowed to prevent strain on the glass fibers. OverviewAn optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite ) is a type of cable that is used in. Optical fibers are used by utilities as an alternative to private point-to-point microwave systems, or communication circuits on metallic cables.
