Fiber Fused Couplers

Fiber Fused Couplers


coupler_sUnited Optronics’ optical couplers are capable of separating an optical signal on a single optical fiber into two in a designated ratio, and can perform the opposite task of combining two signals into one.

Our WDM couplers are capable of dividing two wavelengths on a single optical fiber into two wavelengths on two fibers, and can likewise combine two wavelengths on two fibers onto a single fiber.
