Fiber Optic Ratio Coupler – 90:10 Splitter

Description

Fiber Optic Ratio Coupler – 90:10 Splitter

Overview
A 90:10 fiber optic ratio coupler splits optical power into two outputs — 90% to the main output and 10% to the secondary. This type of coupler is commonly used in FTTH, PON, and other fiber optic networks for monitoring, signal tapping, and secondary device connections while keeping maximum power on the main link.
