Product Description

HYC's FBT coupler has excellent performance parameters：

The FBT coupler has lower insertion loss than the PLC with the same number of branches and has a wide operating wavelength.

Low insertion loss compared to PLC product

Operating wavelength 1310±40&1550±40nm

The FBT coupler has an optional split ratio of 1% to 50% for customers to choose. The tolerance of the split ratio is ±2% to ensure the accuracy of network monitoring.

Typical uniformity≤1.0dB

The FBT coupler provided by HYC can support the harsh environment of -40 ° C ~ +85 ° C to ensure the stable transmission of signals.

Small size, easy to install

The FBT coupler is packaged in a round steel tube and is small in size, making it easy to install in more applications.

Multiple modes, Customizable

The FBT coupler not only available in a variety of split modes and package types, but also can be customized according to customer requirements.

Size : Φ3.0×L45mm Tube Type : 250um fiber

Size : Φ3.0×L54mm Tube Type : 900um loose tube

Size : L90×W20×H10mm Tube Type : 2.0/3.0mm loose tube

Network construction

The FBT coupler has different split ratios and is suitable for real-time monitoring of optical network data or power.
