This WDM reflective assembly employs a T2/R98 optical distribution design, achieving approximately 2% transmission and 98% reflection within a wide 1250–1650nm wavelength band. It is suitable for custom optical paths requiring high reflection rates and limited transmission sampling.
2. Key Features
T2/R98 Optical Ratio: Approximately 2% transmission and 98% reflection, suitable for high-reflection optical paths.
1250–1650nm Wide Operating Wavelength Band: Covers multiple commonly used single-mode fiber communication bands.
Low Reflection Path Insertion Loss: RIL ≤ 0.25dB or ≤ 0.3dB, accepted according to agreed batch ratios.
High Return Loss: RL ≥ 50dB, helps reduce the impact of interface reflections on the optical path.
SMF-28e Single-Mode Fiber: Facilitates integration with common single-mode fiber systems.
Equal Optical Path Structure: Both fibers are fabricated according to equal optical path requirements, suitable for components requiring path consistency.
Compact glass tube structure: Compatible with OD 2.78 * ID 1.81 * L6mm glass tube.
Non-fixed assembly: Components are inserted into the glass tube but not fixed inside.
Length determined by customer-supplied materials: Adaptable to customer-supplied glass tubes, dual fibers, and lenses.
Easy for subsequent integration: Simple foam packaging, suitable for customers to perform further assembly or encapsulation.

4. FAQ
Q1: What does T2/R98 represent?
T2/R98 indicates that the nominal optical power ratio of the component is approximately 2% transmission and 98% reflection. Specific splitting ratio tolerances need to be confirmed according to the final technical agreement.
Q2: What is the operating wavelength range of the product?
The product operates in the wavelength range of 1250–1650nm, suitable for single-mode fiber optic paths within this range.
Q3: What are the RIL performance specifications?
Current specifications use a batch distribution method: Approximately 70% of products: RIL ≤ 0.25dB Approximately 30% of products: RIL ≤ 0.3dB It is recommended to further clarify the sampling method and batch determination rules in the order or inspection standards.
Q4: What type of optical fiber is used in the components?
The product uses SMF-28e single-mode fiber. The dual-fiber is processed according to the equal optical path requirement.
Q5: What is the product length?
There is no fixed length. The final length is determined based on the actual dimensions of the glass tube, dual-fiber, and lens provided by the customer.
