Passive Optical Components，T2/R98 WDM Reflection Assembly for 1250–1650 nm Broadband Optical Integration

Passive Optical Components,T2/R98 WDM Reflection Assembly for 1250–1650 nm Broadband Optical Integration

The WDM Reflection Assembly is a passive fiber optic subassembly specified with a nominal T2/R98 optical ratio across the 1250–1650 nm wavelength range. It incorporates SMF-28e fiber, a dual-fiber structure, a lens, and an OD 2.78 × ID 1.81 × L 6 mm glass tube supplied as part of the customer-provided material set.

• Nominal T2/R98 optical ratio — supports applications requiring a small transmitted portion and a predominantly reflected optical signal.
• 1250–1650 nm wavelength range — provides a broadband optical operating requirement for compatible passive systems.
• Reflected-path insertion loss grading — defines two RIL acceptance levels for project-specific performance control.
• SMF-28e fiber construction — supports integration with standard single-mode fiber assemblies.
• Equal optical path length configuration — helps maintain consistent path geometry in the dual-fiber assembly.
• Customer-supplied optical components — allows the assembly process to follow the specified glass tube, dual fiber, and lens combination.
• Glass-tube insertion without fixation — supports downstream positioning or final bonding by the customer or subsequent assembly process.
• No color marking — meets applications where fiber identification is handled through drawings, positioning, or external labeling.

• WDM reflection modules
• Optical power reflection assemblies
• Passive optical monitoring subsystems
• Broadband fiber optic test equipment
• Fiber sensing assemblies
• OEM optical component integration
• Lens-coupled fiber assemblies
• Custom passive optical modules

Optical performance can be tested according to the agreed specification. Key parameters are verified before shipment, including the optical ratio, reflected-path insertion loss, and return loss when their test paths are defined in the approved specification.

• Customer-material integration: The assembly process can follow the supplied glass tube, dual-fiber component, and lens configuration.
• Defined optical-path construction: Equal optical path lengths support controlled integration into dual-fiber optical assemblies.
• Project-specific optical testing: RIL, RL, wavelength points, and port directions can be verified according to the agreed test definition.
• Flexible downstream assembly: The non-fixed glass-tube configuration allows subsequent positioning or bonding within the customer’s process.
• Support for validation and supply planning: The configuration can be reviewed for sample assembly, small-batch verification, and subsequent quantity requirements.

It is intended for passive optical assemblies that require most of the optical signal to be reflected while a smaller portion is transmitted.

It nominally indicates approximately 2% transmission and 98% reflection. The allowed ratio tolerance and measurement method should be confirmed in the approved specification.

The supplied requirement states 1250–1650 nm. Confirmation is required on whether all optical limits apply across the full range or only at selected test wavelengths.

The assembly uses SMF-28e fiber in a dual-fiber configuration.

The optical components are inserted into an OD 2.78 × ID 1.81 × L 6 mm glass tube without internal fixation.

No fixed finished length has been provided. The final length follows the dimensions of the customer-supplied glass tube, dual fiber, and lens.

Yes. Test reports can be provided upon request after the wavelength points, optical paths, acceptance limits, and reporting format are agreed.

Please provide the operating wavelength, T/R ratio and tolerance, fiber type, assembly drawing, customer-supplied material dimensions, package requirement, target RIL and RL specifications, test-port definition, and estimated quantity.

For a technical review or quotation, please provide the required operating wavelength, channel or optical-path definition, fiber type, connector requirement if applicable, assembly length, package requirement, target optical specifications, and estimated quantity. Please also include the customer-supplied glass tube, dual-fiber and lens drawings, together with the T2/R98, RIL, and RL test definitions.
