Overview
The AFL OFI-400HP is a specialized optical fiber identifier designed to detect signals in single-mode fibers carrying high optical power levels. It is engineered for use in environments where high-power signals, such as those in CWDM/DWDM systems, amplified signals, or pump lasers associated with EDFA and Raman amplifiers, are present.
The unit operates by clamping onto the fiber to create a controlled macro-bend, allowing a small amount of light to escape safely for analysis. This non-intrusive method enables technicians to identify specific fibers and detect traffic without the risk of disrupting revenue service.
Key Features
-
High Power Detection
Capable of detecting signals with power levels from +33 to -40 dBm, suitable for high-intensity fiber networks. -
Universal Head Design
Two-position head supports 250μm and 900μm coated fiber, 3mm jacketed fiber, and ribbon fiber without requiring plunger swaps. -
LCD Power Monitoring
Backlit display provides clear visualization of fiber core or relative power levels during installation and maintenance. -
Traffic Identification
Detects traffic, CW, and 270, 330, 1000, and 2000Hz tones for accurate link verification. -
Safety Alerting
Integrated warning system alerts users if power levels rise above 23dBm via an LCD indicator. -
Rugged Ergonomics
Lightweight 6-ounce design ensures portability for field technicians working in various deployment conditions.
Applications
- Fiber network installation and maintenance
- DWDM and CWDM network verification
- Rerouting and restoration of fiber services
- Identification of pump lasers in EDFA/Raman amplification systems

Frequently Asked Questions
Does this unit require different heads for different fiber sizes?
No, the OFI-400HP features a two-position head that configures for 250μm/900μm coated fiber, ribbon fiber, and 3mm jacketed cable without manual adjustments.
Can I use this on live revenue-bearing fiber?
Yes, the macro-bend method is designed to be non-intrusive and safe for testing without disrupting revenue service.
What is the recommended calibration interval?
The manufacturer recommends a calibration interval of three years.
Does it detect tones?
Yes, it detects CW as well as 270Hz, 330Hz, 1kHz, and 2kHz tones.
What happens if the detected signal is too high?
The unit includes a safety feature that displays a warning message on the LCD if power levels exceed 23dBm.
