Televes mini tester OPM VFL pre optické a RJ45 dátové káble model OPMVFLRJ45

Televes Mini test device OPM VFL for fiber and RJ45 data cables model OPMVFLRJ45 is a compact handheld tester that integrates an optical power meter (OPM) and a visual fault locator (VFL) while providing basic RJ45 cable continuity checks. The unit is intended for technicians and installers working with optical fiber links and Ethernet copper cabling, offering quick verification of optical signal level and fault location in single-mode and multimode fibers together with simple identification of RJ45 wiring continuity.

Advantages

The device combines OPM and VFL functions in a single pocket-sized instrument, enabling measurement of optical power levels and visual identification of breaks or high-loss points. Its compact design and straightforward interface make field measurements fast and portable. The integrated RJ45 continuity check adds convenience for mixed fiber and copper network tasks, reducing the need to carry multiple tools.

Suitable for

• Installation and commissioning of fiber optic links
• Routine maintenance and troubleshooting of optical networks
• Locating breaks, bends or high-loss points in fiber with visual fault locator
• Basic continuity checks of RJ45 Ethernet cables during network setup
• Field technicians and network engineers needing a compact test tool

Key specifications

• Combined functions: optical power meter (OPM) and visual fault locator (VFL)
• Wavelength support for optical testing suitable for common single-mode and multimode fibers
• Handheld, compact form factor for field portability
• Connector compatibility for standard fiber connectors and an RJ45 interface for copper checks
• Battery-powered operation for on-site measurements

How to use

Connect the fiber under test to the appropriate optical connector on the tester, select the required test mode for power measurement or visual fault locating, and read the measured optical level on the display or observe visible red light emission for fault finding. For RJ45 cable checks, insert the Ethernet connector into the RJ45 port and verify continuity according to the tester indications. Follow standard safety practices when using a visual fault locator: avoid direct eye exposure to the emitted light and remove fiber connectors from active transmitters before inspection.

Recommendations

Use the optical power meter mode to establish a baseline signal level before and after installations. Use the visual fault locator for short-range fault location and connector inspection only; for longer distances or precise loss measurements, combine readings from the OPM with reference measurements. Store the device in a clean, dry case and replace batteries as required to ensure reliable field operation.
