FOT-20A Power Meter
The FOT-20A Power Meter is compact, accurate, rugged and easy-to-use instruments for both power and loss testing. Like all of EXFO's handheld power meters, the FOT-20A can be calibrated to a custom wavelength.
Features:
- Direct loss measurement in dB
- Five electronically calibrated wavelengths
- Shockproof holster also acts as storage compartment for fiberoptic adapters and replacement battery
- Auto-off function
- Power measurements in dB, dBm and W
Performance
The FOT-20A incorporates EXFO's linear amplification technology and are traceable to NIST. It offers five calibrated wavelengths, and perform 2 kHz signal detection for fiber identification. Unit configurations are available with germanium or high-power germanium detectors. An electrical offset nulling feature makes the FOT-20A ideal for operation in extreme temperature conditions.
Ruggedness
The FOT-20A Power Meter meets Telcordia's strict drop-test requirements. A complete range of EXFO fiber-optic adapters is available for connector interface. A single 9 V battery powers these units for over 14 hours.
Applications
- Transmitter power measurements (dBm and W)
- Fiber-link loss testing (dB)
- Component insertion-loss testing (dB)
- Fiber identification with 2 kHz signals
- LAN installation and maintenance applications

EXFO FLS-130A
Features
- Single- or dual-wavelength configuration
- 2-kHz signal generation for fiber identification
- Dual powering: 9 V battery and AC adapter/charger
- Auto-off function
- Rigid carrying case and shockproof holster with strap
- Equipped with EXFO’s Universal Interface, except for certain FOS-120A models
Versatility
The FOS-120A Light Source and FLS-130A Laser Source feature single- and dual-wavelength sources from single or double ports. The units deliver continuous wave (CW) signals for power/loss measurements and 2-kHz signal generation for fiber identification. Certain FOS-120A models and all FLS-130A models are equipped with EXFO's Universal Interface.
Unit Powering
Powering options include a 9 V battery and a standard AC adapter. The battery life offers a minimum of seven hours of continuous operation. An auto-off function with a 10-minute timer is included to preserve battery life.
