Pen Shape Visual Fault Locator

NSVF Pen Shape Visual Fault Locator is a compact but powerful fiber optical cable test tool, with an output power up to 1mW / 10mW/ 20mW/ 30mW, which can be used to locate sharp bends & breaks in jacket or bare fiber within 5km,8km more than 10km. It can also be applied to identify the connectors in patch panels and identify the fibers during splicing operation. The choice of a continuous wave output mode for steady fault illumination or a flashing output mode makes for easier fault location.

It is a fact that fiber end-face contamination is a major cause of network outages and downtime. Newsun Tech fiber inspection products enable network technicians and other personnel to safely inspect fiber endfaces for contamination and verify the effectiveness of fiber cleaning procedures.

Newsun Tech offers the best solutions for manufacturing fiber optic cable assemblies. Almost as critical to the equipment used to manufacture fiber optic assemblies are the tools used to test and inspect. At Newsun Tech, we have focus on both the Production and the Field Test and inspection. Newsun Tech works with our customers to make sure their manufacturing procedures produce the highest quality jumpers at the most effective cost.

Newsun Tech focuses on several areas to ensure industry-leading solutions and best practices including: Visual fault locator, fiber optical power meter, Fiber Optic Connector handle test tools Kit, 250X/400X Handheld Fiber Optic Inspection Microscope, and etc..

Production Test and Inspection is generally used in lab type settings where the systems remain stationary. They are built to handle large volumes and typically test to a higher degree of accuracy. This equipment is not only used to provide test reports for customers, but it also allows for the collection of large segments of data that can be reviewed for improvements in the production processes.

Field Test and Inspection pieces of test equipment are designed to be highly portable with internal power supplies and smaller footprints. They are well suited for troubleshooting, mapping and certifying fiber optic networks during and after installation in the field.

We provide the highest quality equipment backed with industry-leading technical support and exceptional customer service. With cutting edge equipment, automation, and process controls.

Critical Areas in the Test STEP

Accurate Test Results: Improper test station setup can and will result in inaccurate testing results. “False Negatives” needlessly increase your rework, while “False Positives” potentially send non-conforming product to your customers.

Multimode Cable Assembly Testing: Proper mode-conditioning is essential to ensure accurate Multimode cable assembly testing.

Test Lead Quality: Essential and often overlooked. Consider your Test Leads to be part of your test equipment, and should be made to the highest quality possible — most importantly, Test Lead connectors should have excellent core-to-ferrule-OD concentricity.
