Single Mode Miniaturized Fiber Optic Coupler

Single Mode Miniaturized Fiber Optic Couplers perform the same basic function as single mode 2 x 2 fiber optic couplers i.e. splitting and tapping optical signal in number of applications. The additional feature is the miniaturized housing which makes them useful for any compact application. FiberLogix manufactures All-Fiber miniaturized couplers from proven fused technology with variety of optical performance at different wavelengths to fulfill system designer's requirements. These compact devices provide low insertion loss, extremely low back reflection, low polarization dependence and stability over variety of environmental conditions. In house process expertise allow to have extremely tight control on the optical performance, quality and reliability. These devices are designed to meet Telcordia standardsGR1209 andGR1221.
