The 70/30 Triple Window Coupler is engineered for modern fiber communication networks that demand accuracy, durability, and long-term reliability. It splits the incoming optical signal so that 70% of the power flows to the primary output while 30% is routed to the secondary path—ideal for monitoring, cascading, or multi-point distribution. Supporting triple-window operation (1310nm / 1490nm / 1550nm), this coupler is widely used in FTTH deployments, CATV systems, and telecom infrastructures. Its low insertion loss, high return loss, and compact design make it perfect for indoor and outdoor enclosures, patch panels, and network cabinets.

70/30 Triple Window Coupler
The 70/30 Triple Window Coupler is a precision optical splitter used in fiber-optic networks to divide light signals in a 70% and 30% ratio across triple-window wavelengths. Designed for CATV, FTTH, and broadband distribution systems, it ensures stable signal transmission with minimal loss. Built with high-grade materials, it delivers consistent performance across 1310nm, 1490nm, and 1550nm windows.
