Low Price Guarantee

What's special about this portable laser source?

  • Detects sharp turns, breaks, cracks and other loss-inducing flaws for up to 32.8' (10m) of optical fiber, providing for easy installations, maintenance and repair
  • Backlit LED display shows power rating, output mode, and frequency, making it easier to test several lines at once
  • Can be used to easily locate connectors in patch panels, eliminating a great deal of confusion when working with densely populated network equipment
  • Variable power output modes from 0-8 dBm ensures coverage when working with darker tube colors and provides for longer distance testing
  • Works with bare fibers and can be used to single out necessary fibers in splicing operations, greatly reducing the risk of costly mistakes

FAST KitFAST™ Connector Universal Tool Kit - AFL
Designed to work with AFL's line of FAST fiber optic connectors, this all-in-one kit has everything you need to strip, clean, mark, cleave and terminate optical fibers packed into a convenient carrying case.
MicroCare Fiber Connector Cleaning SticksMicroCare Fiber Connector Cleaning Sticks
MicroCare’s Cleaning Sticks are designed with a molded fibrous polymer tip instead of a cloth or foam based tip, which can leave behind lint or other fibers.
IDEAL Fiber Inspection MicroscopeFiber Optic Pro Optical Multi-Tester
These units combine a power meter and a 3-wavelength laser source, which are for use in optical fiber network installation and maintenance applications. Thanks to their ample data storage space, these testers are perfect for field testing and transferring the test results to PC through USB interface.

The LS series offer excellent stability and portability for accurate fiber optic testing. Single output port provides stable laser power at dual wavelength. The compact unit operates in either continuous wave (CW) mode or modulated mode. A low battery indicator reminds the user of replacing the battery.

Singlemode Patch Cords Singlemode Patch Cords
From per meter
Singlemode is an optical fiber, with a small core (2-9 microns that supports one mode). The mode Size (standard ie 8.3/125) is stamped on the yellow cable jacket. Singlemode is most commonly used for high speed, long distance applications.
