Description

FOBER FBT Coupler (50/50 Steel Tube Type) – 2 Piece

The FOBER FBT Coupler (50/50 Steel Tube Type) is a premium-grade passive optical device designed to split and distribute optical signals with precision. Built using Fused Biconical Taper (FBT) technology, this coupler ensures stable signal performance and consistent power distribution across optical fiber networks. Supplied as a pack of 2 pieces, it is ideal for telecom providers, FTTH integrators, and CATV network engineers looking for reliable and robust optical signal splitters.

Whether you’re managing a centralized headend system or distributing fiber connectivity to end-users in a FTTH setup, this coupler guarantees low insertion loss, excellent durability, and superior compatibility with standard telecom wavelengths.

Balanced 50/50 Split for Uniform Signal Distribution

The defining feature of this FBT coupler is its 50/50 split ratio, offering equal signal distribution between two output fibers. This balanced output is especially useful in scenarios where two branches of a network require equal signal strength — such as redundant fiber paths, test/monitoring points, or even distribution to multiple endpoints in a passive optical network.

This uniform split ensures optimal signal performance across the network, improving both efficiency and signal quality over long distances.

Fused Biconical Taper (FBT) Technology

FBT couplers are created by fusing and tapering two or more optical fibers together under heat. FOBER uses advanced FBT technology, ensuring precise core alignment and minimal signal distortion. This process results in a coupler that offers low insertion loss, high return loss, and broad wavelength compatibility, typically covering 1310 nm and 1550 nm — the standard transmission wavelengths for most fiber optic systems.

The FBT technology used in these couplers is cost-effective yet high-performing, making it a preferred choice for many passive optical network installations.

Durable Steel Tube Housing

Both couplers come encapsulated in stainless steel tube-type enclosures that offer excellent mechanical protection and environmental resistance. The steel tube prevents damage from external factors such as physical impact, moisture, dust, and temperature fluctuations, allowing these couplers to be deployed confidently in indoor or outdoor environments.

This sturdy construction extends product life and reduces maintenance frequency, thereby lowering long-term operational costs.

High Optical Performance

FOBER FBT Couplers are designed to deliver excellent performance across key optical parameters:

Insertion Loss (IL): Typically less than 3.5 dB, ensuring minimal signal attenuation during splitting.
Return Loss (RL): Greater than 55 dB, reducing back reflection and improving transmission quality.
Directivity: Ensures signal flows in the correct direction without unwanted feedback.
Wavelength Range: 1260 nm to 1650 nm, compatible with most single-mode transmission systems.

Ease of Installation

These couplers are equipped with fiber pigtails and support industry-standard SC/APC or SC/UPC connectors (customizable). This makes them easy to install into fiber distribution panels, splice trays, or direct integration with network cabling systems. The compact design also saves space, making it suitable for high-density deployments.
