|Single mode couplers:
FONT's Single mode couplers split light from one fiber into two or combine light from two fibers onto one fiber with minimum loss. This feature of single mode couplers, which allows for duplex transmission on single fiber, is highly desirable in fiber optic network maintenance, administration and testing. FONT manufactures three types of single mode couplers namely; narrow band couplers with 30nm bandwidth, wavelength flattened couplers with 80nm bandwidth and wavelength independent couplers with 280nm bandwidth. Fig.1 depicts a typical spectral response of FONT's narrow band couplers within 1300nm - 1800nm.
Custom designed single mode couplers:
While Single mode couplers are essential to the operation of fiber optic-based telecommunication networks, cable TV and Local Area Networks (LANs), they are also widely used in sensor technology, robotics technology and laboratory test and measurements. FONT's single mode couplers are available in variety of package styles.
