Single mode cordage is typically which colors?

1. Red or green

2. White or blue

3. Orange or slate

4. Violet or yellow

The correct answer is: Orange or slate

Single mode cordage is typically associated with specific color codes that provide a standardized way to identify fiber types in optical networks. The most commonly used colors for single mode fiber are orange and slate. This convention helps technicians and engineers quickly distinguish between single mode and multi-mode fibers in various applications. Orange is specifically designated for single mode fibers because it is easy to spot and creates a clear contrast against other fiber types, while slate is often used as a secondary identifier to further distinguish single mode cables. This color coding system is important for ensuring proper installation, maintenance, and troubleshooting of fiber optic networks, allowing for efficient identification of fiber types during network deployment and repair. In contrast, the other color combinations listed are typically associated with multi-mode fibers or different applications, making them unsuitable for identifying single mode cordage.
