The Noyes OPM1-2C is a handheld optical power meter for precise measurement of optical power in fiber optic networks. Engineered for field deployment, it delivers straightforward operation with minimal controls—ideal for testing and troubleshooting across premises, telco, and broadband fiber infrastructure. Paired with a compatible light source, the OPM1-2C determines attenuation and insertion loss of multimode or single-mode fiber optic cables.

– Key Features
• Two-control interface: ON/OFF and wavelength selection
• Low battery indicator provides advance warning of power depletion
• Compact, rugged construction rated for field environments
• Multi-wavelength calibration across C-band and extended infrared range
• Selectable resolution accommodates high-precision and general measurements
– Typical Applications
• Fiber optic cable attenuation measurements
• Optical power verification in active networks
• Insertion loss characterization of multimode and single-mode fiber
• Field troubleshooting and network commissioning
– Compatibility & Integration
The OPM1-2C accepts Noyes thread-on style connector adapter caps. Adapter caps are ordered separately and must match the required connector type (ST, SC, FC, or equivalent). Operation with LED or laser light sources enables loss measurement across both multimode and single-mode fiber installations.
