90/10 Triple Window Coupler

The 90/10 Triple Window Coupler is a precision optical component designed to split fiber signals in a controlled 90% / 10% ratio. It is widely used in CATV, FTTH, and telecom networks where continuous signal monitoring is required without disturbing the main transmission line. This coupler allows technicians to tap 10% of the signal for testing or diagnostics while maintaining 90% signal strength on the primary path. Built with high-quality optical fibers and a durable triple-window housing, it delivers low insertion loss, stable performance, and long service life in both indoor and outdoor installations.
