DOWELL Attenuators are qualified for submarine networking system.
DOWELL Singlemode Attenuators are manufactured by Build Out Process to get excellent operational stability and highly automated workstation to have superior repeatability & uniformity.
Patented technology focused on all attenuated fiber & perfect polishing treatment results for nice quality in terms of low ripple, no visible scratch, cracks, chips, blemishes or pits under 400X DORC, and specialty that RL< -55 for any dB value.
We offer 1~20 dB and standard attenuation values at 3, 5, 10, 15 and 20 dB, advantaging economy scale for mass productive supply and custom-made attenuation value meeting your specific requirement, supported by our technical team to obtain the best synergy.
