81600B keysight tunable laser source description
The KEYSIGHT 81600B is a tunable laser source module for a wide range of applications in optical communications and optical testing. The series achieves high signal-to-noise ratio (>70 dB/nm) through low Self-Source Emission (low SSE) technology and features fast and accurate scanning capability covering the full wavelength range from 1260 nm to 1640 nm with no wavelength gap. In addition, the 81600B is equipped with a built-in high-performance 60 dB attenuator and a high-precision wavelength meter (±3.6 pm) to ensure excellent measurement performance.
Key features and specifications
Low Spontaneous Emission (SSE) Signal Output: The 81600B series achieves high measurement range through low spontaneous source emission with a signal-to-noise ratio greater than 70 dB/nm, which enables them to measure filters with high dynamic range.
Variable scanning speed: Scanning speeds of up to 80 nm/s make fast and accurate scanning over the entire wavelength range possible.
Wide tuning range: Wide tuning range units covering all transmission bands from 1260 nm to 1640 nm.
Built-in wavelength meter: features excellent wavelength accuracy of ±3.6 pm, which is essential for accurate wavelength measurements.
High optical output power: up to +9 dBm output power with a built-in high performance 60 dB attenuator, which means stable performance even at high power levels.
Options
Option 200: A full-wavelength tunable laser source with a 200 nm tuning range and 70 dB/nm source-to-source spontaneous emission ratio, suitable for crosstalk measurements of better than 70 dB on 8-channel CWDM multiplexers.
Options 160, 150 and 140: offer other wavelength ranges with two optical outputs and a choice of ports for high power or low SSE.
Options 142 and 132: feature a single high-power output port, where option 132 covers the wavelength range from 1260nm to 1375nm.
These modules can be inserted into the bottom slot of the Keysight 8164B Lightwave Solutions mainframe to provide users with a flexible test solution.The 81600B series is designed to provide the full wavelength range of 1260nm to 1640nm with no wavelength gaps using the minimum number of lasers to provide maximum flexibility in test instrument selection.
What are the typical application scenarios for the 81600B laser in a WDM system?
Testing of CWDM systems: The 81600B laser can be used to test Coarse Wavelength Division Multiplexing (CWDM) systems. Due to its wide tuning range and high source-to-source spontaneous emission ratio, it can perform accurate crosstalk measurements on CWDM multiplexers, which is critical to ensure system performance.
Testing of DWDM systems: Although the 81600B laser is primarily used for testing of CWDM systems, it can also be used for some testing of dense wavelength division multiplexing (DWDM) systems. This is because it can cover the full wavelength range of 1260nm to 1640nm, which gives it some flexibility in testing DWDM systems.
Debugging of fibre optic communication systems: During the debugging of fibre optic communication systems, the 81600B laser can be used as a light source for simulating signals at different wavelengths in order to check the transmission capability and signal quality of the system.
Fibre optic sensing system: In the fibre optic sensing system, 81600B laser can be used as a beam combining technique for pumping signal light, which helps to improve the sensitivity and accuracy of the sensing system.
The application of 81600B laser in WDM system mainly focuses on system testing, debugging and sensing technology, its tunable characteristics make it able to adapt to the needs of different wavelengths, so as to play an important role in a number of fields.
