FTTH Fiber Optical Single mode Dual Window FBT Coupler
Descriptions
Fiberlink's FBT Single mode Dual Window Fiber Couplers are used to distribute optical signals to two output fibers. We offer various types of single mode FBT coupler including standard couplers, polarization independent couplers, wavelength independent couplers and wavelength flattened couplers. These FBT couplers are highly stable. They have low insertion loss, low polarization sensitivity and excellent uniformity.
