Product Description
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 cannot accept the signal generated from
a high-power light source.
HNK attenuator feature a proprietary type of metal-ion doped fiber which reduces 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. HNK attenuator are capable
of performing in the 1310nm and 1550nm.
HNK 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 Dependent Loss
(PDL) and a stable and independent wavelength distribution makes them ideal for DWDM.
