Optical Fiber Identifier

FEATURES

• Optical fiber identifier with integrated 10mW VFL and optical power meter
• Detects signal presence, attenuation, direction, and approximate power using macrobending technology for 250µm, 900µm, 2mm, and 3mm fiber cables
• Tone detection capability at fixed frequencies of 270Hz, 1kHz, and 2kHz
• Universal adapter design eliminates the need to replace clamp blocks for different cable sizes
• Built-in VFL function with 10mW output power for quick fault location
• Integrated optical power meter supporting multiple calibrated wavelengths
• Low battery monitoring function alerts users when battery replacement is required
• Includes soft carrying case for protection and portability
