Lanview LVO237930 network cable tester for fibre optic cables with red light colour

The Lanview LVO237930 network cable tester is a reliable diagnostic tool specifically designed for fibre optic cables. Featuring a prominent red light colour, this visual fault locator helps technicians easily identify breaks, bends, and other physical faults in fibre links. It is an essential instrument for professional network installation, troubleshooting, and ongoing maintenance tasks, ensuring optimal signal transmission and performance in various optical communication setups.

Advantages

This cable tester offers significant practical benefits for network technicians working with fibre optic infrastructure. Its design includes a specialized laser case ground feature that effectively prevents electrostatic discharge damage during handling. The device provides extended operational readiness with a long battery life supporting up to sixty hours of continuous use. Furthermore, its 10mW output power ensures clear visual tracing over considerable distances, while the compact and lightweight black housing allows for comfortable field use.

Suitable for

• Detecting breakage, defects, and bending in fibre optic cables
• Identifying faults located within the OTDR blind zone
• Completing quick end-to-end fibre identification
• Fibre tracing and continuity checking during and after installation
• Optical network routing in field environments

This device is not suitable for testing copper-based network cables such as Ethernet or coaxial cables. It is designed exclusively for visual fault location in optical fibre systems and cannot measure data throughput, network speed, or electrical signal characteristics.

Key specifications

• Cable type: Fibre optic
• Light colour: Red
• Optical power: 10mW
• Product colour: Black
• Dimensions: 29 mm width, 175 mm depth, 29 mm height
• Battery life: Up to 60 hours

To use the tester, insert the terminated fibre optic cable into the designated optical port of the device. Activate the laser emission to project the red light into the fibre strand. Visually inspect the cable run to locate any points where light escapes, which indicates breaks, sharp bends, or structural defects. Always ensure the optical connector is clean before insertion to maintain accurate results.

What to consider before purchase

• Verify that your network infrastructure uses fibre optic cables rather than copper cables
• Check connector compatibility with your existing fibre patch cords and adapters
• Assess your typical working distances to ensure the 10mW power output meets your operational requirements
• Ensure appropriate safety precautions for handling visible laser radiation are maintained

Always avoid looking directly into the optical output port or the end of an active fibre cable when the laser is enabled to prevent potential eye injury. Store the device with the protective cap attached when not in use to keep the optical interface free from dust and debris.
