Today high bandwidth premise networks rely on fiber-optic infrastructure. Proper installation and
maintenance of fiber cabling are imperative to improve technician productivity and ensure cabling
system performance. Whether you require basic fiber verification capabilities, advanced troubleshooting,
inspection, or loss and power measurements, an optical power meter (OPM) is the best first-line fiber
instrument to meet your needs. It offers an accurate and cost-effective testing solution for the fiber optic
network together with a light source. This article will help you understand optical power meters.
What is an Optical Power Meter?
An optical power meter (OPM) is a testing instrument used to accurately measure the power of
fiber optic equipment or the power of an optical signal passed through the fiber optic cable. It
also helps to determine the power loss incurred by the optical signal while passing through the
fiber optic media. OPM has a calibrated sensor that measures an amplifier circuit and a display. It
is measured in dBm or mW and can adapt to different connectors such as SC, ST, FC, etc.

Types of OPM
There are two types of OPM: Normal and PON OPM.
Normal OPM measures the optical power in the fiber optic link with a calibrated wavelength value
of 850/980/1300/1310/1490/1550/1625.
PON OPM can test the optical power values of voice, data, and video signals, supporting
EPON/GPON test. It is ideal for PON network construction and maintenance. In addition, PON
OPM provides simultaneous measurement at all three wavelengths (1310/1490/1550nm) on the
fiber.

OPM provides the following features and benefits:
 User self-calibration function
 Auto power off after 10 minutes without operation
 Standard FC/SC/ST interchangeable port
 Backlight LCD for night operation
 REF setting function
 Intelligent backlight control function
 Auto wavelength and frequency identification
 High storage capacity, precision, stability, sensitivity, and durability
 USB communication port for data transfer
 Compact design, easy operation, and easy to use
Applications
OPM is used in telecommunication networks, CATV networks, FTTx networks, PON networks,
LAN/WAN, education and research in optical communication, etc.
Conclusion
OPM is used to identify optical fiber, measure optical attenuation, verify continuity and evaluate
fiber link transmission quality. It provides high accuracy, high durability, a wide wavelength range,
a compact design, and easy operation. Sun Telecom specializes in providing one-stop total fiber
