FBT Coupler 90:10 – PLC Ratio 1×2 Steel Tube (Pack of 10), Triple Window, 0.9mm, 1 Meter
This PLC Ratio FBT Coupler 90:10 is a compact, durable optical component made for efficient signal splitting in fiber networks. It supports triple wavelengths (1310/1490/1550nm) and comes enclosed in a 0.9mm steel tube. The coupler offers stable performance with low insertion loss—≤0.65dB on the main line and ≤10.5dB on the tap. It’s perfect for FTTH, GPON, and EPON setups. This pack of 10 couplers works well for splicing, custom terminations, and long-term passive use.
