COMBE Filter (Combining Filter) is an Optical Communication Filter specially designed by MULTI IR for Wavelength Division Multiplexing (WDM) systems. Its core function is to "couple" optical signals of multiple different wavelengths into a single optical fiber for transmission, greatly improving the utilization rate of optical fiber bandwidth. The product integrates the technical advantages of DWDM Filter - Dense Wavelength Division Multiplexing Filter and CWDM Filter - Coarse Wavelength Division Multiplexing Filter, supporting the combining processing of 2-16 channels of different wavelengths (1530-1565nm). Each channel has an insertion loss of ≤ 0.3dB and a channel isolation of ≥ 35dB, which can effectively avoid crosstalk between signals of different wavelengths. This product adopts high-precision optical coating technology, the wavelength tolerance is controlled within ±0.2nm, and it is compatible with WDM combining units from different manufacturers; at the same time, it has high stability, the wavelength drift is ≤ 0.1nm/℃ in the environment of -40℃~85℃, and the performance attenuation is ≤ 5% after long-term operation test (10000 hours); combined with MULTI IR's OEM customization capability (OEM Optical Filters), the number of combining channels and wavelength range can be adjusted according to customer needs, providing a highly integrated combining solution for multi-service optical transmission systems.
