This steel tube type coupler offers outstanding durability, precise signal handling, and exceptional stability, making it an ideal solution for both single-mode optical communication systems and optical signal monitoring.
Built with the time-tested Fused Biconical Taper (FBT) technology, this coupler provides reliable performance in a wide range of environments. Whether you’re expanding a fiber-to-the-home (FTTH) deployment, setting up an optical signal monitoring system, or integrating control signals, the FOBER 95/5 coupler delivers precise light splitting and long-lasting service.
Key Features
95/5 Splitting Ratio
The FOBER FBT Coupler is engineered to split 95% of the optical signal to the primary path and 5% to the secondary. This is especially useful for signal monitoring without significantly affecting the main transmission line.
Fused Biconical Taper Technology
Based on traditional FBT manufacturing, this device uses precision-fused optical fibers to achieve stable and accurate signal splitting.
Steel Tube Encapsulation
The coupler is housed in a stainless steel tube that protects the internal structure from mechanical stress, environmental hazards, and temperature fluctuations.
Single Mode Fiber Compatibility
Supports G.652D or G.657A fibers, ensuring optimal performance in single-mode fiber applications across telecom, data, and CATV networks.
Low Excess Loss & High Directivity
Offers low insertion loss and high directivity, ensuring signal integrity, efficiency, and minimal back reflection during operation.
