With hybrid copper-fiber cabling becoming increasingly popular for extended-distance applications, we thought it warranted to take a closer look at these cables, the power they deliver and testing and troubleshooting considerations.
Hybrid copper-fiber cables are available in a variety of constructions, including multimode or singlemode fiber. They can include a single fiber or multiple fibers depending on the application and number of devices being connected. For example, optical network terminals (ONTs) used in passive optical networks operate over a single fiber whereby signals are transmitted simultaneously in both directions over separate wavelengths using wavelength division multiplexing (WDM) technology—1310nm for upstream data and 1490nm for downstream data.
