E2000 Fiber Optic Attenuator

Posted by Teleweaver on 19:50 with No comments
A 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.
Teleweaver attenuators 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, which function by misdirecting rather than absorbing the light signal. Teleweaver attenuators are capable of performing in the 1310, C and L Bands.
TELEWEAVER attenuators 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.
