Question

What is an optical fiber multimeter (OFM)?

Answer

An OFM is an essential handheld tool for optical technicians, comparable to multimeters used by electrical technicians. OFMs quickly measure multiple key optical parameters such as loss (dB), optical return loss (dB), length (meters) and power (dBm). They help technicians verify fiber optic link health and troubleshoot potential issues.
