What is the maximum attenuation for the OM5 version of multimode optical fiber cable at 935 nm?

For OM5 multimode optical fiber cable, the maximum attenuation at 935 nm is specified as 2.3 dB/km. This specification is crucial for understanding how much signal loss occurs over distance when using this type of fiber. OM5 fiber is designed for high-speed data transmission and can support wavelength division multiplexing (WDM) in the 850 to 950 nm range, making it suitable for various applications, including short-range data center interconnects.

The value of 2.3 dB/km reflects the design and manufacturing standards set for OM5 fibers, ensuring that they can provide efficient performance while minimizing signal loss. Knowledge of attenuation values is essential for network design, as it helps engineers determine how far they can run the fiber before signal degradation becomes an issue. Lower attenuation values are preferable because they translate to better performance and longer transmission distances without the need for signal repeaters or boosters.

Therefore, the correct answer aligns with the technical specifications outlined for OM5 multimode fiber, making it an appropriate choice for this question.
