AFL: Optical Fiber Identifier

The AFL Optical Fiber Identifier (OFI-200) is a rugged, handheld tool used to detect live traffic, test tones (270, 330, 1000, 2K Hz), no signal, and signal direction in singlemode fiber—without disconnecting the fiber. Its two-position plunger fits 250 µm, 900 µm, ribbon, and 2–3 mm jacketed fiber, eliminating the need for adapters. Ideal for fast, non-disruptive fiber identification in the field, even in tight splice trays or low-light conditions.

Connector Type

• No Connector Required
  Clamps directly onto 250 µm, 900 µm, 2 mm, 3 mm, or ribbon fiber.

Benefits & Applications

• Safe Live Fiber Identification
  Detects live traffic and tones without disconnecting the fiber—prevents technician-induced outages.
• Quick Field Fiber Tracing
  Identify fibers in splice trays or crowded routes using continuous wave (CW) or test tone signals.
• Works Across Fiber Types
  Built-in plunger adjusts for multiple fiber sizes—no adapters to carry or swap in the field.

Key Features

• Detects no signal, live traffic, and tones (270, 330, 1000, 2K Hz)
• Indicates direction of signal transmission
• Two-position plunger fits multiple fiber types (250 µm to 3 mm and ribbon)
• No adapters required—works across common fiber sizes
• Rugged, lightweight, handheld design with backlit LCD display
