Product Description

OM 4 Optical 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.
