In our fast-paced technological world, this transmitter is stepping up to address the vital needs of high-speed data processing.
Addressing the Rising Demand for Data
As sectors increasingly incorporate artificial intelligence and machine learning, the pressure on data center throughput is growing at an astonishing rate. With the escalating demand for quicker data transmission, manufacturers are hurrying to meet modern industry benchmarks, like IEEE 802.3dj. The introduction of the Optical Reference Transmitter is a timely solution to these challenges, offering essential tools for compliance validation and ensuring interoperability at speeds exceeding 200Gbit/s per lane.
Performance-Boosting Features
This state-of-the-art reference transmitter is equipped with outstanding features crafted to meet industry needs. Utilizing the M8050 series bit error ratio tester (BERT), it can deliver both clean and stressed signals to test optical receiver designs at remarkable rates of up to 120 GBd per lane. This functionality provides vital backing for compliance testing in line with the forthcoming IEEE 802.3dj standard, making it an indispensable resource for engineers developing future-proof optical communication systems.
A Flexible Solution for Optical Challenges
A significant advantage of the new transmitter is its ability to produce a variety of intensity-modulated/direct detected (IM/DD) signals, such as NRZ, PAM4, PAM6, and PAM8 waveforms. This versatility enables researchers to examine transmission capabilities of up to 400Gbit/s per lane, particularly when paired with the Keysight M8199B Arbitrary Waveform Generator (AWG). This powerful combination positions it as a reliable solution for advanced research and development endeavors.
Streamlined Operations for Consistent Results
Designed for operational efficiency, the modulator includes common drive signals and automated bias control, simplifying user interactions while ensuring reliable performance. Additionally, the Optical Reference Transmitter offers versatile optical input options, featuring a built-in DFB laser as well as compatibility with tunable lasers, making it appropriate for a variety of testing situations.
A Complete Testing Solution
The Optical Reference Transmitter is an integral part of Keysight's comprehensive N4917DJCA Optical Receiver Stress Test solution, working flawlessly with the M8050A Bit Error Ratio Tester. This collaboration removes the need for in-house transmitters, allowing users to replicate a 120 GBd optical transmitter. Such capabilities enable customers to validate their optical receivers in diverse conditions, addressing aspects like optical extinction ratio, TDECQ, and stress factors such as noise, jitter, and interference.
Adaptability Across Various Wavelengths
In response to the ever-changing demands of high-speed optical communications, this product supports multiple wavelength grids—LR4, ER4, and CWDM4—making it a versatile tool for different applications. Its adaptability allows researchers and engineers to effectively meet various testing requirements.
Voices of Innovation
Armin Loeffler, Director of Broadband & Photonics Business Segment at Keysight, highlighted the impact of this new technology, saying: "The Optical Reference Transmitter signifies a major leap in optical testing technology. Thanks to its low Vpi, we can eliminate the need for RF amplifiers in many cases. This significantly reduces jitter and noise, while ensuring that our automated bias control operates smoothly without unwanted spectral components. It’s truly a game changer for the industry."
