High power Visual Fault Locator (Model.No.: NOFL-500)
NOFL-500 is an optical instrumentation device that identifies faults along the optical fiber under test (FUT). Emitting visible high-powered laser (red) of over 50 mW into the FUT, it helps the users identify the FUT at opposite position or detect faults through the light emitting from the end of the FUT or fault positions up to 15 km in case of SMF (Single Mode Fiber).
Portable size and easy manipulation makes it suitable for installation and maintenance of optical network.

The features of the device are as follows:
- For longer use time with high-powered laser source, it provides Li-Ion chargeable battery inside so that it is not required to replace batteries.
- The users can control the output power of the laser source in five steps (from sub-mW to tens mW); it makes the battery use time longer and keep the users’ eye from damage.
