FOBER FBT COUPLER (90/10 STEEL TUBE TYPE) (2 NOS)

FOBER FBT Coupler (90/10 Steel Tube Type) – Pack of 2

High Precision Optical Signal Splitter for Advanced Fiber Optic Applications

The FOBER FBT Coupler (90/10 Steel Tube Type) is a premium passive optical device specifically engineered to split or combine optical signals with high precision. This coupler uses Fused Biconical Taper (FBT) technology to provide a 90%/10% power split, making it ideal for applications that require minimal signal tapping without significantly impacting the main transmission line.

Packaged in a durable steel tube housing, this coupler is built to withstand harsh environmental conditions and mechanical stress, ensuring long-term reliability. Whether you’re managing FTTH networks, data centers, CATV systems, or passive optical networks (PON), this coupler is a must-have component for seamless signal distribution and monitoring.

Key Features

• 90/10 Optical Power Split Ratio
  Splits 90% of the optical signal to the main line and 10% to a secondary port—perfect for low-loss monitoring or backup applications.

• FBT Technology
  Utilizes Fused Biconical Taper manufacturing process for high performance, excellent uniformity, and low insertion loss.

• Stainless Steel Tube Casing
  Provides enhanced mechanical protection and shielding against environmental hazards, temperature fluctuations, and corrosion.

• Single Mode Fiber Support
  Built for single-mode fibers (G.652D/G.657A), optimized for long-distance transmission.

• Pack of 2 Units
  Convenient packaging for field installations, system upgrades, or multiple deployment scenarios.

Technical Specifications

Applications

The 90/10 split configuration makes this FBT coupler ideal for applications requiring minimal signal tapping or light monitoring:

• FTTH (Fiber to the Home) Networks

• CATV (Cable Television) Distribution

• Passive Optical Networks (PON)

• Telecommunication Transmission Systems

• Optical Signal Monitoring or Testing

• Enterprise Backbone Networks

Its low impact on the main transmission path makes it especially useful in signal tapping or security monitoring scenarios, where the integrity of the main signal must be preserved.

Advantages

✅ Low Loss on Main Line (90%) – Ensures uninterrupted signal flow to the primary destination.
✅ Ideal for Monitoring and Tapping – Diverts just enough signal for secondary use without major loss.
✅ Robust and Reliable – Designed to operate in both indoor and outdoor environments with wide temperature tolerances.
✅ Easy Integration – Compact size and optional connectors for quick deployment in fiber distribution boxes or ODFs.
✅ Pack of Two – Economical option for multi-point deployment or backup installations.
