Fiber Optic Attenuator is a passive device used to reduce the
amplitude of a light signal without significantlychanging the wave
form itself. This is often a requirement in Dense Wave Division
Multiplexing(DWDM) andErbium Doped Fiber Amplifier(EDFA)
applications where the receiver cannot accept the signal generated
froma high-power light source.HNK attenuator feature a proprietary
type of metal-ion doped fiber which reduces the light signal as it
passesthrough. This method of attenuation allows for higher
performance than fiber splices or fiber offsets or fiberclearance,
which function by misdirecting rather than absorbing the light
signal. HNK attenuator are capableof performing in the 1310nm and
1550nm.HNK attenuator are capable of withstanding over 1W of high
power light exposure for extended periods oftime, 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. Complied
