The Ermenrich NetGeeks NU25 Optical Multimeter is a multifunctional device that can be used to measure optical power, find cable breaks, and determine other characteristics of a fiber optic network and its components.
The VFL (Visual Fault Locator) function allows you to assess cable damage using light signals. There are three types of such signals: steady light, slow flashing and fast flashing. Other network test results are displayed on a backlit color TFT screen, such as the connector crimping quality test and the frequency of the detected signal. The device's connector is protected from dust and water by a removable plastic cap.
The device can operate on one of six main wavelengths: 850, 980, 1310, 1490, 1550, or 1625 nm. The VFL function has a separate wavelength of 650 nm and detectable frequencies of 270 Hz, 1 kHz, and 2 kHz. The device is equipped with standard FC/SC/ST optical connectors as well as an RJ45 network connector. The Ermenrich NetGeeks NU25 multimeter supports single-mode (SM) and multimode (MM) cables.
Key Features:
- The device is powered by a built-in non-removable 3.7V lithium battery
- To save energy, the automatic shutdown function activates after 30 minutes of inactivity.
- There is six hours of battery life on a full charge.
- Optical power measurement in the range –60 to +8 dBm
- Supports FC/SC/ST optical connectors and one RJ45 network connector
- Three additional service functions: frequency detector, cable crystal head QC, VFL
The kit includes:
- Transmitter
- Remote module
- USB Type-C Cable
- Pencil case
- User guide and warranty certificate
