2x2 50/50 FBT Coupler with Corning HI1060 Bare Fiber for Optical Power Splitting，Passive Optical Communication Components

The 2x2 50/50 FBT Coupler is a fused biconical taper fiber optic coupler designed for balanced optical power splitting in OEM and laboratory optical assemblies.

• 2x2 balanced 50/50 coupling ratio — supports even optical power distribution for splitting and routing functions.
• FBT coupler structure — provides a compact passive solution for fiber-based optical assemblies.
• Insertion loss below 3.4 dB — helps control link loss in signal splitting applications.
• PDL below 0.2 dB — supports more stable optical performance where polarization variation needs to be limited.
• Corning HI1060 fiber — provides a defined fiber platform for integration into compatible optical systems.
• 250 μm bare fiber configuration — supports direct splicing and compact internal routing in OEM modules.
• 3 × 50 mm steel tube package — enables space-efficient installation in optical assemblies.
• No connectors — allows flexible termination based on downstream assembly requirements.

• Optical power splitting
• Fiber optic test equipment
• OEM optical module integration
• Optical sensing systems
• Signal monitoring assemblies
• Laboratory fiber optic setups
• Passive optical routing
• Fiber-based subsystem development

Optical performance can be tested according to the agreed specification. Key parameters are verified before shipment, including coupling ratio, insertion loss, and polarization dependent loss. Test reports can be provided upon request. Customized inspection requirements can be discussed, including path definition, fiber length verification, and package-related inspection items.

• Balanced optical splitting for applications that require approximately equal power distribution.
• Compact OEM-ready format with bare fiber and steel tube packaging for direct integration.
• Defined fiber and proof-test requirement based on Corning HI1060 fiber and 200 kpsi standard.
• Support for project-specific review of fiber length, package details, and inspection requirements.
• Suitable for sample validation and production planning in optical module and subsystem development.

It is used for balanced optical power splitting in fiber optic assemblies, test setups, and passive routing applications.

It means the optical power is split into two approximately equal paths, with an allowed ratio tolerance of ±1.5%.

The supplied configuration uses Corning HI1060 fiber.

No. This version is supplied without connectors and is intended for direct splicing or custom termination.

It uses 250 μm transparent bare fiber rather than buffered or connectorized pigtails.

The coupler is supplied in a 3 × 50 mm steel tube package.

Yes. Test reports can be provided upon request.

Please provide the operating wavelength, port configuration, fiber type, connector requirement, fiber length, package requirement, target optical specifications, and estimated quantity.

For a technical review or quotation, please provide the operating wavelength, port configuration, fiber type, connector type or bare-fiber requirement, fiber length, package requirement, target optical specifications, and estimated quantity. If a specific coupling ratio tolerance, packaging method, or inspection format is required, these details should also be included in the inquiry.
