Fiber Optic Ratio Coupler – 80:20 Splitter

Description

Fiber Optic Ratio Coupler – 80:20 Splitter

Overview
An 80:20 fiber optic ratio coupler divides the optical signal into two outputs, with 80% of the power sent to the main line and 20% to the secondary. It is commonly used in FTTH, PON, and other optical networks for partial power tapping, monitoring, and linking secondary devices while maintaining strong primary transmission.
