FBT Coupler 70:30 Ratio – 1×2 Steel Tube Optical Splitter, Triple Window – Pack of 100
The FBT Coupler (70:30 Split) is a 1×2 fused optical splitter that divides signals with precision across 1310nm, 1490nm, and 1550nm wavelengths. Its 0.9mm steel tube design and 1-meter fiber length make it durable and easy to install.
This coupler features a 30% output (blue) with ≤5.50 dB insertion loss and a 70% output (orange) with ≤1.67 dB loss. With low PDL and triple-window support, it performs reliably in FTTH, telecom, and passive optical networks. The pack includes 100 connector-free units for bulk deployment.
