60/40 Triple Window Coupler

The 60/40 Triple Window Coupler is engineered for accurate and stable optical power distribution in modern fiber networks. It routes 60% of the signal to the primary output and 40% to a secondary path—perfect for cascading networks, monitoring lines, and controlled signal sharing.  Designed for triple-window operation (1310/1490/1550nm), it performs reliably across FTTH, CATV, and broadband infrastructures. With low insertion loss, high return loss, and a compact form factor, this coupler fits seamlessly into splice closures, ODN cabinets, patch panels, and wall boxes, ensuring long-term performance in demanding telecom environments.
