Available in 1/99, 5/95, 10/90, 20/80, 30/70, 40/60 and 50/50 coupling ratios. Custom coupling ratios are available up on request.

Single mode couplers:
FONT's single mode couplers split light from one fiber into two or combine light from two fibers onto one fiber efficiently and cost effectively. This feature of single mode couplers, which allows for duplex transmission on a single fiber, is highly desirable in fiber optic links. FONT manufactures narrow band couplers with +/- 15nm bandwidth and wideband couplers with +/-100nm bandwidth.

Tap couplers:
FONT's tap couplers are extremely important in accessing the signal without altering the state of polarization of the signal. FONT's standard, wideband tap couplers are available in 1% to 5% coupling ratios with Polarization Dependent Losses (PDL) as low as 0.05dB.

Custom designed single mode couplers:
FONT also manufactures custom wavelength Single Mode Couplers operating within 355nm to 2000nm. range with minimum loss. Coupling ratios within 1/99 to 50/50 are available.

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 aerospace technology, sensor technology, robotics technology, biomedicine, laboratory test and measurements and R&D. FONT's single mode couplers are available in variety of package styles.
