High-Precision Optical Power Measurement

The FOBER FB-50B03 delivers accurate optical power measurements with a wide dynamic range, ensuring reliable test results across various network environments. It supports both absolute and relative power measurements, which is essential for fiber loss testing, link validation, and signal verification.

Whether you’re working on passive optical networks (PON), fiber backbones, or last-mile FTTH installations, the FB-50B03 helps you verify signal strength and identify losses quickly and efficiently.

Wide Wavelength Range with Multiple Calibration Points

The FB-50B03 supports measurements over a broad wavelength range, typically from 800nm to 1700nm, covering all standard fiber optic transmission bands. It comes pre-calibrated for six popular wavelengths:

• 850nm

• 1300nm

• 1310nm

• 1490nm

• 1550nm

• 1625nm

This makes the device suitable for a wide range of applications, including FTTx networks, DWDM systems, and metro and long-haul optical links.

User-Friendly Design and Interface

The FB-50B03 features a clear backlit LCD display, providing excellent visibility of measurement data in various lighting conditions, including dark equipment rooms and bright outdoor environments. The intuitive interface allows technicians to:

• Easily switch between wavelengths

• Choose between measurement units (dBm, mW, µW)

• Set a reference level for loss testing

• Check battery and signal status

It also includes a “REF” function, allowing users to store a reference power level and measure optical loss by comparing real-time values to the reference.

Rugged and Portable Construction

Designed for field use, the FB-50B03 is compact, lightweight, and built to withstand tough working conditions. It features:

• Shock-resistant outer casing

• Protective rubber boot to guard against drops and impacts

• Dust-resistant keypad

• Ergonomic grip for comfortable handling during extended use

Its rugged build quality ensures long-term reliability, even in demanding outdoor and industrial environments.

Long Battery Life and Energy Efficiency

Powered by either rechargeable lithium batteries or standard AA batteries, the FB-50B03 provides 8–10 hours of continuous operation. An auto power-off feature helps conserve battery life during periods of inactivity, and a low battery indicator alerts users in advance.

With USB charging support (depending on model variant), it’s convenient for on-the-go charging using power banks, laptops, or in-vehicle adapters.

Connector Compatibility and Accessories

The FB-50B03 supports a wide range of fiber connectors, including:

• FC/SC/ST adapters

• Universal connector port for quick switching

• Interchangeable adapters to support custom network setups

It comes with a complete kit that may include the power meter unit, FC/SC adapters, user manual, batteries or charger, and a protective carrying case.
