| Single Mode Dual Window Wavelength Flattened Couplers --WFC-1¡Á2, 2¡Á2 |
¡¡Wavelength flattened couplers can be used to split
light from one fiber to two or combine light from two fibers to one
and provide high performance across a broad wavelength region (from
1270 to 1590nm). WFC couplers are ideal for use in two color OTDRs,
full duplex transmission on a single fiber, multicolor sensors, and
trunk/loop branching. These small devices are insensitive to the operating
wavelength and provide low optical loss with high directivity.
