Single wavelength couplers provide optimal performance around specifical nominal center wavelengths. Wavelength flattened fiber optic couplers extend the optimal wavelength range to a band around specified central wavelengths. Broadband couplers are operational over both the 1310, 1480, 1550 , 1625, […]
