For OS2 outside plant singlemode optical fiber cable, what is the maximum attenuation at 1383 nm?

The correct answer is based on the specifications for outside plant singlemode optical fiber, particularly at the wavelength of 1383 nm. For OS2 fiber, the maximum attenuation allowed at this wavelength is 0.4 dB/km.

In the context of optical fiber communication, attenuation refers to the reduction in signal strength as light travels through the fiber. Lower attenuation values are desirable as they indicate better performance and longer distances for signal transmission without the need for regeneration.

OS2 fiber is designed to meet specific performance levels for long-distance communication, and the 0.4 dB/km maximum attenuation at 1383 nm reflects industry standards established to ensure high-quality transmission with minimal signal loss. This value fits within widely accepted parameters, allowing for optimal performance in telecommunications and data networks, ensuring that signals maintain integrity over extended distances.

Understanding these specifications is crucial for professionals involved in the installation and maintenance of optical fiber networks, as they assure compliance with industry standards and effective network performance.
