What is the Agilent 86146B Optical Spectrum Analyzer?
The Agilent 86146B is part of Agilent’s high-performance OSA family, designed for precision testing of optical networks, DWDM systems, fiber amplifiers, lasers, LEDs, and passive optical components.
Unlike many earlier OSAs, the 86146B offers wider wavelength coverage (600–1750 nm), making it suitable for both telecommunications testing in the 1310 nm and 1550 nm bands as well as research applications that require visible to near-infrared spectral analysis.
Its key features include:
- Wavelength range: 600–1750 nm
- High wavelength accuracy for repeatable testing
- Narrow resolution bandwidth options for precise DWDM channel measurements
- Built-in applications for laser characterization, OSNR (Optical Signal-to-Noise Ratio) analysis, and filter testing
- User-friendly interface with graphical trace display and advanced analysis tools
This makes it a workhorse for both R&D labs and production test environments.

Why the 86146B Stands Out
There are many optical spectrum analyzers available, but the Agilent 86146B stands out due to its unique combination of broad spectral coverage, high resolution, and stability.
- Broad Range (600–1750 nm):
Most telecom OSAs only cover 1250–1650 nm. The 86146B extends into the visible spectrum, making it suitable for medical lasers, fiber sensor R&D, and LED testing. - High Resolution:
With resolutions down to 0.06 nm, it can separate narrow DWDM channels or evaluate fine features of laser spectra. - Stability & Accuracy:
The Agilent 86146B’s wavelength accuracy and repeatability make it ideal for compliance testing in regulated industries where repeatable results are mandatory. - Proven Reliability:
Agilent/Keysight instruments are built to last, and many 86146Bs are still in operation worldwide after decades — especially when serviced by professional labs like Aumictech.
Applications of the Agilent 86146B
The versatility of the 86146B OSA allows it to serve in multiple industries. Below are the most common applications:
1. Telecommunications (DWDM, CWDM, OSNR Testing)
- Verification of DWDM channel wavelengths
- OSNR (Optical Signal-to-Noise Ratio) measurement
- Spectral flatness of optical amplifiers
- Testing mux/demux filters in optical networks
2. Laser and Light Source Characterization
- Spectrum analysis of tunable lasers
- Linewidth measurement
- Stability and mode analysis
- LED spectrum validation
3. Research & Development in Photonics
- Optical materials research
- Spectroscopy in the 600–1750 nm range
- Sensor development (fiber Bragg gratings, interferometers)
4. Manufacturing & Production Testing
- Pass/fail verification of optical components
- Batch testing of filters, isolators, multiplexers
- Compliance with ITU-T standards for telecom components
