Isolator separates phone line, equipment
The OC-100/200 from Hark Tower Systems optical telephone line isolator isolates equipment from the telephone line. This is accomplished by using fiber optic technology, converting electrical signals into light, passing this light information through a 4″ fiber gap and then reconstructing the light levels back into electrical signals. This allows the equipment to communicate with the telephone line without being connected to it. This isolator also regulates the current through your equipment. It provides a safe level of current flow through the equipment regardless of the current on the telephone line. There is no need to buy a current regulation device.
Cable assemblies made to order
Tru-Connector’s custom RF coaxial cable assemblies can include flexible and semi-rigid types ranging from 0.074″ to 1.20″ O.D. and can be produced in lengths as long as 150 feet, with any gender combination of plugs, jacks and panel mounts.
