FOBER FBT Coupler (60/40 Steel Tube Type) – Reliable Optical Signal Splitter for Advanced Fiber Networks.
The FOBER FBT Coupler (60/40 Steel Tube Type) is a premium-grade passive optical component designed to split or combine optical signals with high precision. Engineered using Fused Biconical Taper (FBT) technology, this coupler provides dependable performance in single-mode fiber networks. With a 60/40 splitting ratio, it diverts 60% of the optical power to one output and 40% to the second, making it ideal for load balancing, monitoring, and distributing optical signals across two different paths.
The steel tube packaging ensures enhanced durability and environmental protection, enabling stable performance in both indoor and outdoor environments. This FBT coupler comes as a set of 2 units, offering reliable solutions for telecom, CATV, FTTH, and optical testing applications.
Key Features
60/40 Splitting Ratio
Allows optimal power distribution where one output requires more signal than the other. Perfect for split-level or tiered access networks.
Fused Biconical Taper (FBT) Technology
Provides excellent signal transmission with low insertion loss and high stability. This traditional yet reliable method is known for its cost-effectiveness and proven performance in optical signal splitting.
Robust Steel Tube Housing
The steel casing offers mechanical strength and protects internal fiber components from physical damage, bending, or harsh weather.
Single Mode Fiber Compatibility
Designed for use with single-mode fibers (G.652D or G.657A), supporting long-distance transmission with minimal attenuation.
Wide Operating Wavelength Range
Compatible with wavelengths between 1260 nm and 1650 nm, supporting diverse applications in fiber optic communication systems.
Low Insertion Loss & High Return Loss
Ensures signal quality is maintained across both output channels while minimizing reflections.
