What is an Optical Spectrum Analyzer?

Optical spectrum analyzers perform precision optical spectrum measurements to characterize light sources. 

How Does an Optical Spectrum Analyzer Work?

Optical spectrum analyzers have wavelength-tunable optical filters for light to pass through so a photodetector can convert the signal into a proportional electrical current.

Ideal performance for manufacturing tests

The AQ6360 satisfies the typical measurement needs of industrial manufacturing of telecom devices such as lasers, optical transceivers and optical amplifiers.

  • Wavelength range: 1200 to 1650 nm

AQ6370 series compatible operation

The AQ6360 inherits the screen and menu layout from our OSA lineup, which is recognized by thousands of users all over the world as the most intuitive and easy-to-use.

Multi-touch touchscreen

Tap, drag, pinch in and pinch out. The high resolution, responsive 8.4-inch multi-touch capacitive touchscreen makes the operation of the instrument simple and intuitive.

Built-in analysis functions to increase productivity

More than ten data analysis functions are available, including WDM (OSNR), SMSR, DFB-LD, EDFA, and Spectral width.

Ready for remote operation

Ethernet and GPIB remote interfaces
The AQ6360 is equipped with GP-IB, and Ethernet interfaces for remote access and for building automated test systems.

AQ6370D compatible remote commands
It is compatible with both AQ6370D and AQ6317 commands for easy programming.

LD chip and TOSA

The AQ6360 delivers improvements in measurement throughput via a multimode fiber for free space laser beams from wafers, LD chip, TO CAN and TOSA measurements. This is due to the free space input structure of the OSA which accepts multimode fibers without high insertion loss, which occurs when multimode and single mode fibers are mismatched.


LD chip and TOSA

The side mode suppression ratio (SMSR) of laser can be measured quickly and accurately.

NA Conversion Adapter

NA Conversion AdapterThe Numerical Aperture (NA) Conversion Adapter makes measurements with a multimode fiber more accurate and stable. It is a unique adapter designed specifically for Yokogawa OSAs.

Optical transceiver

In conjunction with bit error rate test (BERT) equipment, the AQ6360 can measure the center wavelength and spectral width of transceivers and LD modules.
For testing the BER curve of optical transceivers, the broadband light of an ASE source is added to signals. The high sensitivity of the AQ6360 enables it to measure OSNR conditions more accurately than low performance non grating based designs.

Optical transceiver

Optical amplifier

The AQ6360 has an automated function to easily calculate the Erbium Doped Fiber Amplifier Noise Figure under the name “EDFA-NF”. A typical measurement setup for amplifier testing consists of a set of multiplexed lasers, an attenuator for tuning the laser power level, an optical spectrum analyzer. The OSA takes two high-resolution spectrums. One trace is taken before amplification and one after amplification. From the obtained spectrums, the EDFA-NF Analysis Function automatically detects the laser peaks, extracts the required measurement values, performs the calculations and displays a table with the values of GAIN and NF of the DUT.

Numerical Aperture Conversion Fiber

By connecting a GI 50 or GI 62.5 optical fiber with a relatively large NA to the NA Conversion Fiber, the NA Conversion Fiber reduces the loss that occurs at the input and improves the measurement dynamic range during passive device measurements and the stability of optical level measurements during active device measurements.

Application Note

OSA Macro Program Function

The OSA Macro Program Function enables automated measurement by creating programs for entry of measurement conditions and other tasks. Users can program a sequence of measurement procedures from entry of measurement conditions (e.g., wavelength sweep width, setting resolution) to analyses, data saving, output, and others and eliminates redundant procedures on the production line. The function acts as a controller of other connected devices through the LAN or RS232C port and allows users to build an automatic measuring system without using an external PC and input measurement conditions or output measured results while programs are running.


To accurately measure pulsed light using an optical spectrum analyzer (OSA), it is necessary to understand the characteristics of the OSA and select the appropriate measurement method and settings.


Lack of reliable high-speed internet access in rural regions, due to complicated logistics and the considerable costs involved to extend land-based networks to these areas, has inspired a wave of next-generation applications that will provide greater accessibility and reliability. Making use of “space laser” networks, these revolutionary solutions can relay digital traffic via low Earth orbit (LEO) satellite systems to provide low-latency, high-speed broadband services to communities typically beyond the reach of standard wireless and fiber networks.


Optical transceivers are one of the indispensable key devices for optical communications that interconvert optical and electrical signals.


In a research paper published on, a team of researchers from the University of Virginia, Peking University, Shanxi University, and California Institute of Technology use a Yokogawa Test&Measurement Optical Spectrum Analyzer in order to achieve spectrum measurements above 1200 nm.
