Fiber Optic Length Testers

Fiber optic length testers are essential tools for accurately measuring the length of fiber optic cables, helping to ensure proper installation, troubleshooting, and maintenance. The Beaming Optical Length Tester (BOLT) and the Visual Optical Length Tester (VOLT) provide fast and precise measurements, making them a cost-effective alternative to more complex testing solutions. These testers use advanced optical measurement techniques to determine fiber length without requiring expensive Optical Time Domain Reflectometers (OTDRs), making them ideal for field technicians, installers, and network administrators.

Built for Your Application

Whether you're deploying new fiber optic infrastructure, maintaining existing networks, or verifying cable lengths before installation, these length testers provide a simple and effective solution. Instead of manually measuring each cable, these testers quickly determine fiber length using light-based measurement methods. This helps reduce installation time, prevent costly errors, and streamline troubleshooting when diagnosing fiber link issues.

Key Features & Benefits

  • Accurate Fiber Length Measurement – Precisely measure fiber optic cable lengths using optical signal reflection and looped methods.

  • Time-Saving Technology – Eliminates the need for manual measurements and speeds up the testing process.

  • Cost-Effective Alternative to OTDRs – Provides reliable fiber length measurements without the high cost of traditional OTDR equipment.

  • Easy-to-Use Design – Simple operation makes it ideal for field technicians and network installers.

  • Compact & Portable – Lightweight and rugged construction for use in various field conditions.

  • TAA Compliant & Made in the USA – Ensures high quality and reliability for government and commercial applications.

Available Configurations for These Products

These fiber optic length testers come in two models:

  • Beaming Optical Length Tester (BOLT) – Uses a "looped" testing method, measuring fiber length by sending light through two fibers and calculating the total round-trip time before dividing by two.

  • Visual Optical Length Tester (VOLT) – Uses visual optical testing to determine fiber length efficiently.

Both models offer quick measurement capabilities and ship within 24 business hours.

Common Uses for Fiber Optic Length Testers

  • Fiber Installation Verification – Confirm fiber lengths before deployment to prevent installation issues.

  • Troubleshooting & Maintenance – Quickly diagnose fiber optic cable lengths when testing or repairing networks.

  • Telecom & Data Center Applications – Ensure precise fiber management in large-scale network infrastructures.

  • Government & Enterprise Networks – Used by IT professionals and technicians for high-accuracy fiber length verification.

FAQ

How do fiber optic length testers measure cable length?

These testers use optical signal reflection or looped measurement methods to determine fiber length based on the time it takes for light to travel through the cable.

Do these testers work on all types of fiber optic cables?

Yes, the BOLT and VOLT models are compatible with various fiber types, including single-mode and multimode fiber.

Are these testers a replacement for an OTDR?

While not a direct replacement, they provide an affordable and effective alternative for measuring fiber length when full OTDR functionality is not required.

How quickly do these testers provide results?

Measurement results are available almost instantly, allowing for rapid verification and troubleshooting.

What is the lead time for these products?

Both the BOLT and VOLT models typically ship within 24 business hours.
