The EXFO EPM-500 is a handheld optical power meter engineered for accurate power measurements across fiber optic networks operating at 800 nm and beyond. This field instrument delivers precise readings with reference value setting and requires no offset nulling for reliable operation in diverse test environments. When paired with an ELS-500 Light Source in Auto-Switching mode, it enables semi-automated loss measurement with automatic wavelength switching for error-free testing.
## Technical Specifications
• **Wavelength Range:** 800 nm primary; also capable at 850 nm, 1300 nm, 1310 nm, 1490 nm, 1550 nm, and 1625 nm, extending to 1650 nm maximum
• **Measurement Units:** dB, dBm, and Watt
• **Detector Type:** Ge or GeX
• **Power Source:** Rechargeable battery
• **Laser Safety Classification:** IEC 60825-1 Amendment 2:2001 and 21 CFR 1040.10; Class 1 without VCSEL sources; Class 3R with Visual Fault Locator option
