EXFO FOT-10A Handheld Optical Power Meter

The FOT-10A is a compact, accurate, rugged and easy-to-use handheld optical power meter designed for both power and loss testing of fibre-optic links. It incorporates EXFO's linear amplification technology and is traceable to NIST standards. The FOT-10A offers five calibrated wavelengths and performs 2 kHz signal detection for fibre identification. An electrical offset nulling feature makes it ideal for operation in extreme temperature conditions. It can also be calibrated at a custom wavelength.

FOT-10A Key Specifications:
Detector Type: GeX (2 mm)
Calibrated Wavelengths (nm): 780, 850, 1300, 1310, 1550
Measurement Range: +6 to –60 dBm
Resolution: 0.05 dB
Uncertainty: ±5%
Signal Detection: 2 kHz (fibre identification)
Offset Nulling: Electrical offset nulling for extreme temperature operation
NIST Traceability: Yes
Connector Interface: EXFO Universal Interface (EUI) — interchangeable adapters (FC, SC, ST, LC)
Power: 9 V alkaline battery / AC adapter

EXFO FLS-230A Handheld Fibre Optic Light Source

The FLS-230A is a handheld fibre optic light source from EXFO's legacy portable instrument range, designed for use alongside compatible optical power meters for fibre link attenuation and loss testing. It is suited for singlemode fibre testing and features a compact, rugged form factor appropriate for field use. The FLS-230A also incorporates a Visual Fault Locator (VFL) function for fibre identification and fault finding.

FLS-230A Key Specifications:
Source Type: Laser (singlemode)
Typical Wavelengths: 1310 / 1550 nm
Connector Interface: FC (interchangeable adapter)
Modulation: CW and tone modulation for fibre identification
Form Factor: Handheld, portable
Power: Battery / AC adapter compatible

Typical Applications:
Fibre optic link-loss characterisation
LAN, WAN and telecoms network installation and maintenance
Attenuation testing on singlemode fibre
Field-based power and loss verification

Note: Full and definitive specifications for both instruments should be verified against the official EXFO documentation. Please refer to the EXFO website at www.exfo.com for the most current technical information.
