In this EC&M Tech Talk, Randy Barnett reviews the concepts, cables used and NEC rules Art. 770 Optical Fiber Cable. With the widespread use of fiber and expansion into residential markets, installers find themselves delicate fibers encased in durable cable in various locations. While the article specifies the rules for installation, an understanding of the cable construction, types and the jacket markings helps electrical and communication workers to select and apply the correct products for the application. Splicing and terminating optical fiber is much different than copper. In fact, hands-on training is needed to work with the special tools and connectors needed. Certification is recommended and a list of certification providers appears at the end of the video.
