Fused Single-Mode Standard Coupler 980–106 nm, 50 mW
The Fused Single-Mode Standard Coupler is a high-performance fiber optic component designed for the 980–106 nm wavelength band and supports 50 mW CW power. Built using the mature fused biconical taper (FBT) process, it features low insertion loss (≤0.3dB),), excellent uniformity, and high return loss (≥50dB).). Available in 1×2 and 2×2 port configurations with multiple splitting ratios (1/99, 2/98, 5/95, 10/90, 50/50). Ideal for ultrafast laser systems, fiber amplifiers, fiber sensing, optical communications, test equipment, and optical research. Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards; RoHS certified.
