The 1771-PT3 is a fiber-optic cable that belongs to the 1771 series manufactured and created by Allen-Bradley. This cable is intended to be used with programming systems. The Allen-Bradley 1771-PT3 fiber-optic cable is an indoor-rated duplex cable that is 150 meters long (492 feet). This cable is dielectric and non-conductive, which means that it is not affected by electromagnetic signals or noise. In order to connect two fiber-optic cables together, an Allen-Bradley splice connector is needed. The physical installation is easy, but users could encounter some difficulties while consulting the dB loss budget when using these connectors, since they increase the fiber-optic links’ dB losses.

The Allen-Bradley 1771-PT3 fiber-optic cable can be routed in the same conduits and wire ways of conventional wirings. If the installation is performed underground, it is important to place the cable in a polyethylene conduit. The cable should not be installed in ducts, and users need to make sure to place it in safe locations where other units will not crush it or damage it. If the distance is too long, it is important to notice that too much fiber cable stretching can cause an increased attenuation, this is because the fiber cable has a lower tensile strength than other regular copper cables. Users still have the alternative to use connectors to separate different cables. The environmental operating temperature for the Allen-Bradley 1771-PT3 fiber-optic cable is from -20 to 70 degrees Celsius. This cable has a diameter of 100 meters and two fibers. It also has a resistance of 1.845 feet per pound.
