What is the maximum attenuation of OS2 cable specified at the wavelength of 1550 nm?

The maximum attenuation of OS2 singlemode fiber optic cable at the wavelength of 1550 nm is specified at 0.4 dB/km. This specification is crucial because it reflects the cable's performance in terms of signal loss over distance, which is essential for the efficiency and reliability of optical communication systems.

OS2 fiber is designed for long-distance transmission, and the standard attenuation rate helps ensure that the signal can travel without significant degradation. At 1550 nm, the attenuation is at its lowest compared to other wavelengths, making it the preferred choice for high-capacity long-haul applications. Understanding this specification is key for network design and installation, as it informs decisions about cable routing, distance limits, and overall system design to optimize performance.
