Buying Guide – How to Choose the Best Fiber Optic Cable Tester
Choosing the right Fiber Optic Cable Tester requires balancing your specific testing needs with budget constraints and desired features.
Wavelength Support
Ensure the tester supports the wavelengths you will encounter in your network such as 850nm or 1310nm. Many models cover common telecom ranges but specialized infrastructure might require broader options.
Verify the wavelength list matches your network requirements before purchasing.
Connector Compatibility
Check if the device comes with the correct adapters for your fiber connectors such as SC ST LC or FC. Universal interfaces are convenient but sometimes specific adapters are needed for accurate testing.
Look for kits that include necessary adapters to save time and extra cost.
Visual Fault Locator
A VFL helps identify breaks bends or bad connections by sending visible light through the fiber. Most testers include this but check the output power to ensure it is strong enough for your fiber type.
Prioritize models with adjustable or strong VFL output for better fault detection.
Data Storage
If you need to keep records of your tests look for a unit with built-in memory storage. This helps in tracking network changes over time without manual logging.
Choose devices with enough storage capacity for your expected testing volume.
Battery Life
Field work often requires long-lasting power so consider if the unit uses standard batteries or has a rechargeable option. Battery life impacts how long you can work between charges.
Select a battery solution that fits your daily usage patterns.
Additional Features
Some testers include extra tools like network cable verification or IP testing which can reduce the need for multiple devices. Decide if these extras add value to your specific workflow.
Evaluate if multi-functionality aligns with your overall testing needs.
Durability and Build
Since these tools are used in the field they should be robust enough to withstand drops and daily wear. Look for ruggedized cases or drop-resistant designs.
Choose a model with a sturdy build quality to ensure longevity.
Ease of Use
An intuitive interface with clear displays helps you get accurate readings quickly. Consider models with backlight options or simple navigation menus.
Prioritize user-friendly designs to avoid errors during critical testing.
How to Use and Care for Your Fiber Optic Cable Tester
To use the tester effectively connect the fiber cable securely to the port and ensure the connectors are clean before measurement. This prevents false readings caused by dust or damage at the interface.
For VFL tests ensure you are wearing safety glasses if looking directly into the fiber core as the light source can be bright. Follow the device instructions to activate the light mode and inspect the path for visible red light indicating breaks.
Maintain your tester by storing it in a protective case when not in use and cleaning the optical ports regularly with a lint-free cloth. Avoid exposing the device to extreme moisture or temperatures to prolong its operational life.
Frequently Asked Questions
What is the difference between an optical power meter and a visual fault locator?
An optical power meter measures the strength of light signal passing through fiber to assess signal loss in dBm. A visual fault locator sends a visible red light through the fiber to visually identify breaks sharp bends or connector issues. Many modern testers combine both functions for complete diagnostics.
Do Fiber Optic Cable Testers work with singlemode and multimode fibers?
Most modern testers support both singlemode and multimode fibers but you must check the specifications for the exact wavelengths supported. Singlemode typically uses 1310nm or 1550nm while multimode uses 850nm or 1300nm. Ensure the device covers the ranges used in your network.
How often should I calibrate my Fiber Optic Cable Tester?
Calibration frequency depends on usage intensity and environmental conditions but a common recommendation is once a year for regular use. If the device suffers a drop or shows inconsistent results you should calibrate it immediately to maintain measurement accuracy.
Can I test live fiber with these devices?
Most basic testers and VFLs are not designed for live fiber testing and may damage the device or provide incorrect readings. OTDRs or specific models marked for live line testing are required to measure active signals safely. Check the manufacturer guidelines for live fiber compatibility.
Why is a network cable tester function included in some models?
Including network cable testing allows technicians to diagnose both fiber and copper cabling issues with one tool. It is convenient for environments where both fiber and Ethernet cables are installed and reduces the need to carry multiple devices.
What type of adapters do these testers typically include?
Many units come with universal adapters for SC ST FC or LC connectors but some may require purchasing specific adapters separately. Always check the included accessories list to ensure compatibility with your fiber connector types before testing.
