Single mode Visible/Infrared Wavelength Optical Fiber Coupler (Visible/Infrared Light Beam Splitter)

Employing excellent FBT (fused biconical taper) technology, Lfiber can fabricate desired single mode visible/infrared wavelength optical fiber coupler with precise operating wavelengths and coupling ratios upon request.

Single mode Visible/Infrared Wavelength Optical Fiber Coupler (Visible/Infrared Light Beam Splitter: 405nm, 430nm, 450nm, 457nm, 460nm, 473nm, 488nm, 532nm, 630nm, 633nm, 635nm, 650nm, etc.)

Lfiber offer visible optical fiber coupler (red, green, and blue light beam splitter) for specific applications on request.
This visible light fiber optic coupler is available for the entire visible spectrum from 400 to 700 nm, covering typically visible wavelengths of 405nm, 430nm, 450nm, 457nm, 460nm, 473nm, 488nm, 532nm, 630nm, 633nm, 635nm, 650nm, etc.

Single mode Visible/Infrared Wavelength Optical Fiber Coupler (Visible/Infrared Light Beam Splitter: 780nm, 830nm, 850nm, 980nm, 1064nm, 1480nm, 1570nm, 1590nm, 1625nm, 1700nm, 2000nm, etc.)

The light frequencies used for optical fiber communications are completely invisible, they are all in the Infrared wavelength range. Lfiber’s infrared wavelength optical fiber coupler (splitter) is available for near infrared (NIR) wavelengths and short-wavelength Infrared wavelengths, covering typically infrared wavelengths of 780nm, 830nm, 850nm, 980nm, 1064nm, 1480nm, 1570nm, 1590nm, 1625nm, 1700nm, and 2000nm, etc.
