Color by Numbers
Don't always judge a cable by its color
Although it may be difficult to identify the specific type of copper cable just by looking at the jacket color, it’s a “color by numbers” method when specifying fiber optic cable. Outdoor cables (both copper and fiber) are usually black; however, indoor copper cables can come in an assortment of jacket colors, depending on the end user or installer’s preference. Some choose the common blue or gray, while others choose custom colors – such as brown, which was the case of Hershey Company to match their milk chocolate. And, it’s not unusual to find a combination of colors at one location to identify the different services or applications of twisted pair – such as yellow for voice, blue for data, red for security. However, unlike the rainbow of jacket color offerings of copper, indoor fiber optic colors are yellow, orange or aqua, if the manufacturer follows the TIA-598-C standard.
