Project Description

1.0μm Single-Mode Fused Coupler

DK Photonics 1.0μm single-mode fused coupler are used to split off a portion of light to allow for optical monitoring and feedback. These devices are used extensively in fiber amplifier power control, and in transmission equipment for performance monitoring and feedback control. Our ultra-low polarization dependent loss couplers offer low levels of sensitivity to polarization, enable more effective monitoring and management of optical networks. These couplers are available in a wide range of split ratios, lengths, and packaging. Custom terminations are also available.

Features Applications
·         Low Insertion Loss

·         Low Polarization Dependent Loss

·         High stability & Reliability

 ·         EDFA

·         Fiber Laser

·         Testing Instrumentations
