Q-Fiber G657.B3 Patchcords and Pigtails are designed for indoor applications. Used G657.B3 fibre and special Q-Bend cable construction allows for bending radius 2.5 mm. It helps in quick and easy cable installation. Q-Fiber pigtails and patchcords are perfectly suitable for installation in narrow cable ducts, switching optical circuits as well as connecting transmission equipment. LSZH coating provides not spread flames and non-flammable. Each product is customized, which means pigtails and patchcords can come in any configuration.
