（2+1）x1 MM ポンプシグナルコンバイナー
（アクティブファイバ用SM信号導入型）
Pump Input Wavelength ： 780 ～ 1000 nm
Signal Input Wavelength ： 1064 nm, 1550 nm
Configuration ： 2+1x1
A multimode combiner in a 2+1x1 configuration, with an active SM signal feed-through fiber and an active dual clad output fiber. Supported pump input wavelengths range from 780 – 1000 nm while signal input wavelengths range from 1530 – 1565 nm or 1030 – 1090 nm.
G&H proprietary manufacturing techniques allow the precise fusion of multimode pump fibers to an active SM signal feed-through fiber and an active dual clad output fiber, providing high coupling efficiency over a wide pump wavelength range.
Inclusion of the splice between the passive and active signal fiber within the combiner housing removes the need for an external splice reducing potential back-scatter to the pump sources. G&H power combiners can be fabricated from a range of industry standard fibers allowing ease of splicing to commercially available laser diodes, signal and gain fibers. Custom variants using non-standard fibers are available on request.
