1×2（2×2）Single-Mode Splitter Coupler (Polarization Maintaining or Non-Polarization Maintaining)
2x2 single-mode fused fiber couplers can split a single fiber input into two outputs, and vice versa. These couplers are available in narrowband, broadband and dual-wavelength versions, including 1310/1550 nm broadband couplers. A very small portion, as low as 0.01%, of an extremely costly optical signal can be tapped off and amplified, ensuring the power of subsequent signal transmission.
