3x3, 1x3, 2x2, 1x2 Couplers
Couplers can be used to split light from one or more fibers onto two or three fibers or to combine light from two or three fibers onto one or more fibers. Depending on the transmission system the light can be at one or many wavelengths in the range 1250nm to 1600nm. For different systems couplers of the following types are available.
Single Wavelength Coupler:
Insertion Loss specified for operation at a single wavelength in the range from 1250nm to 1600nm.
Wavelength Flattened Coupler:
Designed to give uniform insertion loss over a broad wavelength band around a centre wavelength of 1310nm or 1550nm.
Dual Wavelength Coupler:
Designed to give a uniform insertion loss over the complete wavelength band from 1260nm to 1600nm.
