What color in the TIA/EIA 598 B color code represents green?

Fiber type
Unused capacity
Outdoor-rated cable
Signal transfer

The correct answer is: Fiber type

In the TIA/EIA 598 B color code, the color green specifically represents fiber type. This standard is used primarily for identifying the colors of the outer jackets of fiber optic cables, as well as the color-coded fibers within those cables. Each color corresponds to a specific type or category of fiber, aiding in organization and identification during installations and maintenance. The other choices—referring to unused capacity, outdoor-rated cable, and signal transfer—do not correlate with color coding in the TIA/EIA specifications. Unused capacity and signal transfer are concepts related to the performance and utilization of fiber optic systems rather than their physical identification through color. Outdoor-rated cables may have distinct characteristics (such as UV resistance) but are not designated in terms of color codes specific to fiber type. Understanding this color coding is crucial for technicians to ensure proper installation and maintenance of fiber optic systems, as it minimizes confusion and enhances accuracy when connecting or troubleshooting fiber networks.
