The Fiber Optic Attenuator 3dB SM Green (Part number: KCULD001) from KERPEN DATACOM is a / Fiber Optic Attenuators with 3.0dB loss.
Single mode fiber uses a LASER light source, is a type of optical fiber with a small core diameter that allows only one mode of light to propagate. It is used in telecommunications and data transmission systems to transmit signals over long distances with low attenuation and high bandwidth. Single mode fiber is ideal for high-speed and long-distance applications, such as internet backbone networks, cable television networks, and fiber-to-the-home (FTTH) services. Its narrow core reduces the dispersion of light, allowing signals to travel further and faster than with multimode fiber.
