Single-Mode Bidirectional Coupler-Double Window Coupler
Single-mode dual-window couplers typically have a bandwidth of ±40 nm and coupling ratios of 50:50, 90:10, and 99:1...... Can be customized by volume. Additionally, the couplers are bi-directional, allowing either port to be used as an input port (see 2x2 Coupling Example tab below), and contain SMF-28e+ fiber optics with a Ø900 µm jacket. Gracyfiber couplers are available with FC/PC or FC/APC connectors, or without connectors.
