Compact Fiber Optic Splitter 1x4 Single Mode Monolithic Fused Coupler Low PDL
Compact Fiber Optic Splitter 1x4 Single mode Monolithic Fused Coupler
Description
1x4 Single Mode Monolithic Fused Coupler manufactured by ANC International Co., Limited is based on fused biconical taper technology. These 1x 4 Single Mode fusion couplers feature compact size, very low insertion loss and polarization dependence, excellent environmental stability and loss uniformity. These 1x4 couplers were designed for power splitting or combining of optical signals. They are widely used for optical modules and the fiber sensors, fiber testing instruments. These coupler can work at customized single wavelength, such as 1310nm, 1550nm, 980nm, 1480nm, etc or work at dual window, both 1310 and 1550nm. They are available in both 1x3 and 1x4 port configurations.
