Visual Fault Locators (VFLs) emit visible laser radiation that can pose a serious risk of eye injury if proper precautions are not followed.

⚠️ WARNING:
Never look directly into the laser beam or into the end of a fiber connected to an active VFL. Exposure to laser radiation may cause permanent eye damage.

Required Protective Measures:

• Always wear appropriate laser safety eyewear when operating a VFL.
• Recommended eyewear must meet or exceed the following minimum specifications:
  • Protection Range: 800–1755nm and 10600nm
  • Optical Density: OD4+ (800–1755nm), OD5+ (10600nm) or higher
  • Standards Compliance: CE EN207 or equivalent
• Ensure eyewear is undamaged, properly fitted, and suitable for the wavelengths in use.

Safe Operating Practices:

• Never point the VFL at yourself or others.
• Do not view active fibers with the naked eye or optical instruments.
• Verify all fibers are inactive before inspection when possible.
• Use appropriate caps or covers on unused connectors.
• Operate only by trained personnel familiar with fiber optic safety procedures.

Important Notice:
Failure to follow proper safety procedures may result in serious injury. The user assumes all responsibility for safe operation and compliance with applicable safety standards.
