Exfo FOT-30A Optical Loss Test Set

The EXFO FOT-30A is a handheld optical loss test set combining an integrated light source and power meter for field characterization of fiber optic links. Single-unit design eliminates the need for separate instruments, reducing setup time and measurement error during network deployment, troubleshooting, and maintenance operations.
