The optical power of the fiber optic cable is too high
Excessive fiber optic signal strength exceeding the specified range can overload the fiber optic receiver when above its operating range, causing high bit error rates or worse. In these situations, network administrators should install fiber attenuators to reduce optical power. The most basic fiber optic measurement is optical power from the end of a fiber. This measurement is the basis for loss measurements as well as the power from a source or presented at a receiver. Receive Power (Rx): Too high (saturation) or too low (weak signal) can cause errors. Fiber optic cables are the unsung heroes behind lightning-fast data. Optical power is a critical parameter in optical communications, referring to the amount of optical energy transmitted through a fiber optic cable.
