OM5 bend‑insensitive multimode fiber is designed for short‑wavelength wavelength‑division multiplexing. Unlike conventional OM4 fiber, which only offers high bandwidth around the 850 nm wavelength, OM5 bend‑insensitive multimode fiber provides high bandwidth across the 850–950 nm wavelength range, offering a fiber solution for 100 Gb/s and 400 Gb/s multi‑wavelength transmission systems.
OM5 bend‑insensitive multimode fiber meets or exceeds the requirements of the ISO/IEC 11801‑1 OM5 specification, the IEC 60793‑2‑10 A1‑OM5 specification, and the TIA‑492AAAF A1‑OM5 specification.
