Optical Spectrum Analyzers - Rent & Buy Certified Used

An optical spectrum analyser (OSA) is an instrument used for measuring the power, wavelength, and noise characteristics of light signals in an optical fibre. Used in telecommunications, manufacturing, and R&D, optical spectrum analysers have a variety of applications in designing, developing, testing, and troubleshooting optical communication systems. Because they can identify and measure signal distortion, they are useful in evaluating the network performance of telecommunications systems. However, they are also useful in manufacturing optical components such as lasers and optical fibres or in characterising the properties of materials in research labs.  

Here at Electro Rent, we understand the importance of being able to access top-quality and highly accurate optical spectrum analysers when and where you need them, without a large capital investment. Depending on your needs and budget, you will find a range of OSAs that may be appropriate for your test and measurement applications, with flexible financial solutions that allow you to get the best from your budget. From flexible OSA rental to carefully selected certified pre-owned devices with large discounts, our range is sure to have an option that works for you.  

Frequently Asked Questions 

How do optical spectrum analysers work? 

Optical spectrum analysers function by dispersing an optical signal into its separate wavelengths. The instrument measures the intensity of the signal at each wavelength using a detector array and generates a visual representation of the spectrum of the signal.  

Using an OSA first involves introducing the signal through the input port such as a fibre optic cable. Inside, the device has a prism or diffraction grating which disperses the light into its separate wavelengths. The detector array measures the power of the signal at each wavelength. The analyser then displays the power level, wavelength, and sometimes also the optical signal-to-noise ratio (OSNR). The spectrum may be viewed as a line or bar graph and will usually be displayed in real-time.  

How do optical spectrum analysers differ from RF and microwave spectrum analysers?  

Optical and RF or microwave spectrum analysers have similar functions in that they measure power in wavelengths, but they measure different frequency ranges and have very different applications. 

RF and microwave spectrum analysers are used in TV and radio broadcasting to detect radio frequency interference as well as in aerospace and defence and some telecommunications industries. They are used for the measurement of signals in the frequency range of several megahertz (MHz) to several gigahertz (GHz), and the exact range of frequencies will depend on the model and make of analyser.  

Optical spectrum analysers are used to measure signal power and noise characteristics of light waves in telecommunications and R&D such as in spectroscopy. These analysers measure signals in the range of terahertz (THz) and petahertz (PHz), although the range of frequencies will often be more limited depending on the intended application of the device.  

What should I consider when choosing an optical spectrum analyser? 

One of the key considerations when choosing an OSA is the range of frequencies that the instrument covers. Depending on your application, you may require a wider or more limited range of measurement. The dynamic range (the range of optical power levels) that the analyser supports is also important to match with your test requirements. 

Furthermore, it's important to select an analyser with the right resolution bandwidth for your needs; if you need to make accurate measurements of small frequency intervals, choosing an OSA with a high resolution is key.  

Other considerations might include the size and portability of the OSA – both benchtop and handheld spectrum analysers are available. The analyser's processing rate may be important, depending on your intended application.  

What is the wavelength range of an optical spectrum analyser? 

While the wavelength range can vary between different models of OSA, a typical wide wavelength range is often around 600 nm to 1750 nm. 

What are the benefits of buying a pre-owned OSA? 

Buying a certified pre-owned optical spectrum analyser allows you to access high quality fully calibrated test equipment at a fraction of the normal price. Our independent experts carefully select and evaluate used optical spectrum analysers in a 23-step certification process to ensure their accuracy and reliability.
