In the digital networking era, massive overhead and underground optical cables form an extensive "neural network" for communications. Cable routing inspection and fault detection constitute fundamental routine work throughout optical cable deployment and daily maintenance. Conventional cable tracing methods suffer from lengthy operation and low efficiency when deployed in harsh field environments and over long-distance fiber routes; worse still, stripping cable jackets or cutting fiber cores commonly causes secondary damage to the cabling system.

With 34 years of expertise in optical communication manufacturing, JILONG Communications addresses core industry pain points and unveils the KL-6500 Optical Cable Identifier. Integrating cable identification and high-performance OTDR in one unit, this tester features non-destructive testing and multi-purpose functionality, resetting industrial benchmarks for fiber testing and field maintenance.

1.  Non-Destructive Cable Tracing, Plug-and-Play Measurement

The flagship innovation of JILONG KL-6500 lies in its single-fiber non-destructive testing technology. Unlike traditional alternatives, it pinpoints target cables without looping fiber ends. Adopting plug-and-play design with no pre-test length measurement required, it drastically cuts construction hours and material expenses.

Optimized for APC connectors, the tester supports a maximum test range of 80 km to satisfy long-haul trunk cable identification demands, serving as an essential tool for telecom field technicians. Operators may flexibly adjust sensitivity and buzzer volume according to on-site field conditions to accommodate diverse application scenarios for streamlined testing.

2. Built-in High-Performance OTDR Module

While non-destructive tracing stands as the KL-6500’s standout advantage, its embedded premium OTDR delivers robust all-round testing capability. More than a regular cable identifier, it doubles as a professional fiber fault tester.

Powered by the integrated high-performance OTDR module, the KL-6500 precisely measures fiber attenuation, splice loss and exact fault coordinates. Its automatic mode completes tests for 10×3m patch cords automatically to boost working efficiency. Boasting a dynamic range up to 35 dB and adjustable pulse width ranging from 10 ns to 20000 ns, it effortlessly handles fiber testing up to 175 km.

3.  8-in-1 All-in-One Multifunctional Integration

To improve troubleshooting accuracy, KL-6500 combines eight core functions: cable identification, OTDR, iOLA（Hawkeye）, fiber inspection probe, optical power meter, visual fault locator, stable light source and network test, covering most mainstream application scenarios in optical communications. The proprietary iOLA (Hawkeye ) function, a paid optional add-on for many competing devices, comes as standard across all KL-6500 configurations. Empowered by advanced algorithms, it intelligently diagnoses PON networks and intricate link failures with one-touch auto-testing, lowering operation barriers and accelerating field work.

Aligned with IoT development trends, KL-6500 supports Wi-Fi remote control for convenient equipment management and data sharing. Wired and complimentary Bluetooth earphones are both compatible; optional GPS positioning is available to navigate directly to fault locations and further enhance on-site productivity.

4.  Industrial-Grade Build for Rugged Field Operations

Engineered to withstand harsh outdoor working conditions, KL-6500 is equipped with a 7.0-inch multi-Touch capacitive touchscreen featuring intuitive UI for easy navigation. A large-capacity 10500mAh battery delivers outstanding endurance: ≥24 hours standby time and ≥12 hours continuous operation to sustain full-day intensive field tasks.

Compact and lightweight at only 1.7 kg, the unit fits comfortably in one hand for easy transportation. Stable operation is guaranteed from -10°C to 50°C, reliably performing amid extreme hot and cold ambient temperatures.

Packed with core merits including non-destructive testing, embedded high-performance OTDR and 8-in-1 integrated functions, JILONG KL-6500 delivers an efficient, damage-free and portable all-round solution for optical engineers.
