80/20 Triple Window Coupler

The 80/20 Triple Window Coupler is a precision fiber-optic device designed to split optical signals in an 80% / 20% ratio, making it ideal for CATV, FTTH, and telecom networks that require controlled signal tapping. It allows 20% of the signal to be used for monitoring or testing while maintaining 80% strength on the main transmission line. Built with a robust triple-window steel housing and high-grade optical fiber core, this coupler delivers low insertion loss, excellent stability, and long-term performance in both indoor and outdoor environments. It is widely trusted by network installers and ISPs for accurate and reliable signal management.
