1×2 Fiber Optic FBT Splitter – No Connector – Unbalanced Split Ratio

1×2 Fiber Optic FBT Splitter – No Connector – Unbalanced Split Ratio

The 1×2 Fiber Optic FBT (Fused Biconical Taper) Splitter with an unbalanced split ratio and no connectors is a cost-effective, reliable solution for optical power distribution in fiber optic communication systems. Designed using time-tested fused fiber technology, this splitter divides one input fiber signal into two outputs with a customized power distribution ratio, ideal for applications that require unequal optical power to different outputs.

Advanced FBT Technology for Flexible Power Splitting

FBT splitters are manufactured using the fused biconical taper technique, where two or more fibers are fused and tapered together while controlling the distribution of optical power. Unlike PLC (Planar Lightwave Circuit) splitters, FBT splitters offer the flexibility of creating customized, non-standard or unbalanced split ratios, such as 90:10, 80:20, or 70:30. This makes them ideal for applications where one output requires more optical power than the other—such as in monitoring systems or redundant network setups.

Unbalanced Split Ratio for Custom Applications

This 1×2 splitter features an unbalanced split ratio, where optical power is intentionally divided unequally between the two output fibers. This configuration allows for more power to be delivered to one channel, while still supplying a measurable signal to a secondary path. Unbalanced splitters are widely used in applications such as signal monitoring, optical network testing, fiber-to-the-home (FTTH), and passive optical networks (PONs), where one leg of the splitter may serve as the primary transmission line, and the other as a monitoring or backup path.

No Connectors for Direct Splicing Integration

This model is supplied without connectors, making it ideal for permanent installation where the splitter will be spliced directly into the fiber network. Bare fiber ends allow for flexible deployment and minimal insertion loss, especially in environments where space is tight, and custom-length pigtails are required. Without connectors, this unit also offers cost savings and reduces reflection loss typically associated with connectorized systems.

Compact, Rugged Design

Housed in a compact and protective steel or plastic tube (based on variant), the splitter is designed for reliability in both indoor and outdoor settings. Its small footprint allows for easy installation in splice closures, wall-mounted boxes, fiber distribution panels, and other network access points.
