50/125 μm OM2 multimode optica fiber, also known as gradient fiber, gradient refractive index fiber, is the fiber with gradient refractive index or gradient distribution of the fiber core area in the cross section (such as parabolic shape). The purpose of adopting the gradient refractive index fiber is to reduce the pattern dispersion of the multimode fiber.This fiber has small dispersion and bandwidth is 1~2 orders of magnitude larger than that of mutant fiber, which is suitable for medium distance fiber communication system.
50/125 μm OM2 bending insensitive multimode fiber meets or exceeds ISO / IEC 11801-1 OM 2 specification, IEC 60793-2-10 A1-OM 2 specification and TIA-492AAAF A1-OM 2 specification.
* Using a proprietary double-layer UV-cured acrylate coating.
* Excellent microbending resistance.
* OM2 multimode fiber optic is used for tight sleeve optical cable performance is superior.
* Stable performance under multiple environmental conditions.
*Superior geometric consistency,Low attenuation
*At 850nm and 1300nm wavelengths with high bandwidth.
*Manufactured using the PCVD process.
*An extremely accurate refractive index profile.
*LAN application video, audio.
*Data services are applicable to Gigabit Ethernet for laser or LED light sources
*Support the use and installation of optical cables at a small bending radius
