This WDM reflective module covers the 1250–1650nm wavelength band and adopts a T2/R98 transmittance/reflection ratio design, achieving approximately 98% optical signal reflection and approximately 2% transmission.
Product Features
Operating wavelength range: 1250–1650nm
Transmission/reflection ratio: T²/R98
Insertion loss (RIL) at the reflection end is controlled according to graded requirements: 70% ≤ 0.25dB, 30% ≤ 0.3dB
Return loss (RL) ≥ 50dB
Uses SMF-28e single-mode fiber
Equal optical path design
Fiber is not color-coded
Assembled through a glass tube; the glass tube is not fixed
Glass tube dimensions: OD 2.78 * ID 1.81 * L 6mm
Product length is determined based on the actual length of customer-supplied materials
Custom-supplied materials include the glass tube, dual fiber, and lens
Uses domestically produced adhesive for component assembly
Uses foam for simple packaging
Customization is supported based on customer-supplied optical components and assembly requirements
