Inquiry

Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output.

Fiber optic coupler is different from WDM. WDM Module or WDM device can divide the different wavelength fiber light into different channels. Fiber optic couplers divide the light power and send it to different channel. 

Single window fiber optic coupler is with one working wavelength. Dual window fiber optic coupler is with two working wavelength. For Single mode fiber, the term means that the fiber is optimized for 1310 nm and 1550 nm; For Multimode fiber, the term means that the fiber is optimized for 850 nm and 1310 nm. 

Choices for fiber optic coupler type include Single window narrow band, Single window Wide band, and Dual window Wide band fiber optic coupler.  

Single Window Narrow band Fiber optics couplers (1310 +/-10nm or 1510 +/-10nm) are designed for a single wavelength with a narrow wavelength window.
