RoHS Optical Fiber Attenuator E2000 / UPC 5dB High Stability Fiber Telecom Use
E2000/UPC fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself. This is often a requirement in Dense Wave Division Multiplexing(DWDM) and Erbium Doped Fiber Amplifier(EDFA)applications where the receiver can't accept the signal generated from a high-power light source.
Fiber optic attenuator feature a proprietary type of metal-ion doped fiber which reduce the light signal as it passes through. This method of attenuation allows for higher performance than fiber splices or fiber offsets or fiber clearance, which function by misdirecting rather than absorbing the light signal. FC attenuator are capable of performing in the 650nm for multimode.
E2000/UPC attenuator are capable of withstanding over 1W of high power light exposure for extended periods of time, making them well-suited to EDFA and other high-power applications.
Low polarization department loss(PDL) and a stable and independent wavelength distribution makes them ideal for DWDM.
