2x2 5/95 FBT Fiber Coupler Corning 1060 200kpsi Low Insertion Loss Low PDL with FC APC on 95 Percent Output，Specializing in the manufacture of passive optical components

The 2x2 5/95 FBT Coupler is an asymmetric fused biconical taper component designed to retain most optical power on a 95% main path while directing a smaller portion to a monitoring or feedback path. It uses Corning 1060 fiber with a 200 kpsi proof-test requirement and 0.9 mm protected pigtails. The specified insertion loss is below 0.4 dB for the main path and below 15.2 dB for the tap path, with polarization-dependent loss below 0.2 dB. The pigtails are 1.00–1.05 m long and use color coding to identify the optical paths. A custom 3 × 50 mm package supports compact integration. The supplied information indicates an FC/APC connector on the white 95% output, while the connector status of the remaining ports requires confirmation.

• Asymmetric 5/95 optical power distribution — maintains the primary signal path while providing a lower-power branch for monitoring or feedback.
• 2x2 port structure — supports two-input and two-output optical routing within passive fiber assemblies.
• Main-path insertion loss below 0.4 dB — helps control optical power reduction along the nominal 95% path.
• Tap-path insertion loss below 15.2 dB — defines the required loss performance for the nominal 5% branch.
• PDL below 0.2 dB — limits optical power variation associated with changes in polarization state.
• Corning 1060 fiber with 200 kpsi proof testing — provides a defined fiber and mechanical screening requirement.
• Color-coded 0.9 mm protected pigtails — simplify port identification during installation, splicing, and testing.
• FC/APC termination on the specified 95% output — provides an angled connector interface where required by the system design.

Optical performance can be tested according to the agreed specification. Key parameters, including coupling ratio, insertion loss, and polarization-dependent loss, are verified before shipment. Test reports can be provided upon request. Customized inspection requirements can be discussed, including individual path measurements, connector verification, port-color inspection, pigtail length checks, and package identification.

• Defined main and tap paths: The asymmetric ratio supports systems requiring a high-power transmission path and a lower-power monitoring branch.
• Mixed termination configuration: The specified FC/APC output can be combined with unterminated pigtails for direct splicing, subject to final port confirmation.
• Project-specific mechanical integration: Pigtail length, port colors, connector placement, and package dimensions can be checked against the assembly drawing.
• Path-by-path optical testing: Coupling ratio and insertion loss can be recorded for each defined optical path.
• Suitable for qualification workflows: The configuration can be reviewed for sample verification, small-batch evaluation, and subsequent supply planning.

It divides optical power between a nominal 95% main path and a nominal 5% tap path. It is commonly used for power monitoring, feedback control, sensing, and passive signal routing.

The operating wavelength has not been provided. Corning 1060 identifies the fiber requirement but does not define the guaranteed wavelength range.

The 95% path carries most of the optical power, while the 5% path provides a lower-power signal for monitoring, measurement, or feedback.

The supplied information indicates that the white 95% output is terminated with FC/APC. The connector status of the other three ports should be confirmed in the final drawing.

The input side uses white for the 95% path and blue for the 5% path. The output side uses white for the 95% path and orange for the 5% path.

The current configuration uses 0.9 mm protective tubing with a stated pigtail length of 1.00–1.05 m. Production is requested at the maximum tolerance.

Yes. Optical performance can be tested according to the agreed specification, and a test report can be provided upon request.

Please provide the operating wavelength, port configuration, coupling ratio and tolerance, fiber type, connector placement, fiber length, package dimensions, target optical specifications, port-color definition, and estimated quantity.

For a technical review or quotation, please provide the required operating wavelength, channel or port configuration, fiber type, connector type and connector location, fiber length, package requirement, target optical specifications, coupling-ratio tolerance, and estimated quantity. A four-port drawing is recommended to confirm the FC/APC output and the unterminated pigtails.
