FOBER MINI OPM FB-260B

Compact Optical Power Meter for Precise Fiber Optic Testing in the Field

The FOBER MINI OPM FB-260B is a compact and reliable optical power meter (OPM) designed for quick, accurate, and efficient testing of optical power levels in fiber optic networks. As fiber optic communication continues to expand in telecommunications, FTTH (Fiber to the Home), data centers, CATV, and enterprise-level infrastructure, technicians require portable and robust tools to keep up with evolving demands. The FB-260B delivers exactly that—powerful performance in a small, easy-to-carry form factor.

Perfect for both professional engineers and field technicians, this mini OPM is a trusted choice for verifying signal strength, testing power loss, and maintaining high-performance fiber optic links.

Compact Design, Powerful Performance

Don’t be fooled by its size—the FB-260B offers exceptional testing capability in a device that fits easily in the palm of your hand or a technician’s toolkit. Despite its miniature form factor, it provides all the essential functions needed for optical power measurement, making it ideal for on-the-go testing, emergency repairs, and routine maintenance in the field.

Its lightweight body and durable construction mean it can be used confidently in indoor, outdoor, and industrial settings without sacrificing measurement accuracy or user experience.

High Accuracy and Wide Wavelength Range

The FB-260B supports a wide wavelength range from 800nm to 1700nm, covering all commonly used optical communication bands. It is pre-calibrated for standard wavelengths, including:

• 850nm

• 1300nm

• 1310nm

• 1490nm

• 1550nm

• 1625nm

With high accuracy (±0.2 dB typical), the device ensures precise measurements of optical power in various types of fiber systems—whether you’re working on single-mode or multi-mode networks.

Multiple Measurement Units and Modes

This device supports three common optical power units:

• dBm (absolute power)

• mW/μW (linear scale)

• dB (relative measurement)

With the REF (reference) function, technicians can set a benchmark and then measure the relative loss along the fiber line—ideal for determining attenuation or troubleshooting weak signal areas. This feature makes the FB-260B particularly useful in loss testing, fiber splicing verification, and fiber link troubleshooting.

Easy-to-Use Interface

The FB-260B is built for simplicity, ensuring even novice users can operate it with ease. Its digital LCD screen provides clear readings of:

• Real-time optical power level

• Wavelength in use

• Battery status

• Measurement unit

• Reference level

A few buttons are all you need to switch wavelengths, change units, or store reference values, making it ideal for fast-paced fieldwork.

Long Battery Life & Auto Power-Off

The optical power meter runs on standard AAA batteries or a rechargeable lithium battery (depending on model variant), offering up to 100 hours of continuous use. The auto power-off function preserves battery life when the device is idle, while a low battery indicator notifies users to recharge or replace batteries in time.

This ensures technicians can complete long jobs without interruption, even in remote areas.

Versatile Connector Support

The FB-260B supports a variety of optical connectors commonly used in the industry. It typically includes an interchangeable adapter head compatible with:

• SC

• FC

• ST

This makes the power meter highly adaptable for different fiber optic testing environments, saving time and reducing the need for separate tools.

Ideal Applications

• FTTH and FTTx installations

• Network maintenance and diagnostics

• Optical fiber splicing validation

• CATV signal testing

• Telecom and metro network testing
