The function of a 0dB fiber optic attenuator

Home / The function of a 0dB fiber optic attenuator

Optical attenuators are passive components used to reduce optical signal power to a controlled level within a fiber optic system. The signal power in fiber optic links is sometimes needed to be strengthened to achieve long-haul data transmission.

dBm

A schematic showing the relationship between dBu (the voltage source) and dBm (the power dissipated as heat by the 600 Ω resistor) dBm or dBmW (decibel-milliwatts) is a unit of power level expressed

Optical attenuator

An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step
