Fibrain Multimode Attenuating Patchcords are characterized by uniform attenuation in both windows of multimode operation (850 and 1300 nm). The available attenuation can be chosen from the 10-40 dB range in 1 dB increments and the attenuation ripple is very low. These devices are also significantly less sensitive to changes in the modal distribution compared to the more traditional multimode attenuators. Each patchcord is delivered with a test report. The patchcords are available with any standard multimode fiber types (OM2, OM3, or OM4) and their length and connectors types can be customized.
