Key Features and Benefits of the Keysight Agilent 81640A Option 071 Tunable Laser Source TLS

The Keysight Agilent 81640A Option 071 Tunable Laser Source TLS offers numerous features designed to enhance performance and simplify optical testing. Below are some of its most significant benefits:

• Extensive Wavelength Range: Operating across a wavelength range of 1510 nm to 1640 nm, the Keysight Agilent 81640A is capable of testing components across both the C- and L-bands. This flexibility allows users to handle a wide range of DWDM components, providing versatility in both research and manufacturing applications.
• Mode-Hop Free Tuning: The 81640A offers continuous wavelength sweeps without any mode hops, ensuring smooth transitions across the wavelength range. This feature is crucial for accurately characterizing components such as optical amplifiers and DWDM filters, where stable wavelength transitions are required for high-precision results.
• Reliable Optical Power Output: The tunable laser source delivers a maximum output power of up to 4 dBm, providing strong, stable signals for testing. This feature is particularly important for applications that require high-power output, such as optical amplifier testing.
• High Wavelength Accuracy and Stability: With absolute wavelength accuracy of ±0.015 nm and repeatability of ±0.5 pm, the 81640A ensures precise, repeatable measurements, making it ideal for applications that demand the highest levels of accuracy. The built-in wavelength meter provides real-time feedback to ensure control over test conditions.
• Straight Contact Connectors: The Option 071 configuration features polarization-maintaining fiber with straight contact connectors. This setup is suitable for general-purpose testing applications where minimizing back-reflected light is not critical. The straight contact connectors offer a more straightforward setup for standard optical testing scenarios.
• Continuous Sweep Functionality: The 81640A enables uninterrupted tuning across the entire wavelength range, making it an excellent choice for applications that require consistent and smooth wavelength transitions. This capability is particularly useful when evaluating the dynamic response of DWDM components.
• High Dynamic Range for Precision Measurements: The Keysight Agilent 81640A provides low source spontaneous emission (SSE) output, ensuring a high signal-to-noise ratio. This feature is essential when measuring crosstalk and characterizing narrowband filters like Fiber Bragg Gratings, allowing for precise results even in challenging testing environments.

Difference Between Option 071 and Option 072

The Keysight Agilent 81640A TLS is available in two configurations: Option 071 and Option 072. The primary difference between these two options lies in the type of fiber connectors used:

• Option 071: This version comes with straight contact connectors, which are ideal for standard optical testing applications where minimizing back-reflection is not as critical. It offers a simplified setup for general-purpose testing tasks.
• Option 072: This version features angled contact connectors, which significantly reduce back-reflection by directing reflected light into the fiber cladding. This is beneficial for high-sensitivity testing environments, where maintaining the highest signal integrity is essential.
