Furthermore, the AH15199B can amplify 140 Gbaud PAM4 signals from various signal sources, such as DSPs , and can directly drive modulators and other devices requiring high amplitude. Therefore, it is a suitable exciter for evaluating optical modulators for 800 GbE and 1.6 TbE digital coherent systems , which are now the focus of attention as next-generation transmission systems, as well as for IM- DD systems widely used in optical communications.
Anritsu meets customer needs by selling this broadband linear amplifier that supports the growth and smooth operation of high-speed networks.
Background to development:
Mobile data traffic is increasing with the growth of AI, machine learning, and other services, but the new increases in communication speeds for servers and network devices are a major challenge.
The next generation of the IEEE 802.3 Ethernet standard for high-speed networks will utilize digital coherence methods, such as 800GBASE-LR1 (for 10 km), 800GBASE-ER1-20 (for 20 km), and 800GBASE-ER1 (for 40 km), as well as the IM-DD method. The Optical Internetworking Forum (OIF) is studying specifications for optical transmission technologies, such as 800ZR and 1600ZR, as well as coherence technology to support increased optical network capacity and accelerate the growth of systems "beyond 1 Terahertz.".
On the other hand, higher transmission speeds suffer greater signal attenuation, so a high-power linear exciter is needed to faithfully amplify the PAM signals and directly excite the modulators.
Product Description
The AH15199B high-power linear amplifier supports 2.0 Vpp signal evaluation at 140 Gbaud PAM4 for high-speed, high-performance data transmission with a low maximum power consumption of 1.5 W. A data rate of 140 Gbaud is equivalent to 140 billion signal changes per second.
The standard, small, dedicated power supply reduces the risk of damage from improper handling.
Technical Terms
*1 Linear Amplifier
Amplifies the input signal at a fixed ratio
*2 PAM4
Abbreviation for Pulse Amplitude Modulation used to increase transmission capacity by amplitude modulation using four voltage levels
*3 Gain
Parameter indicating how many times the sinusoidal amplitude of the input frequency is multiplied at the output; represented as frequency on the logarithmic x-axis and as gain in relative dB units on the y-axis.
*4 Jitter
Parameter indicating the quality of the digital signal as fluctuation over time; greater jitter causes errors in the acquisition of digital signal values.
*5 DSP
Abbreviation for Digital Signal Processor; a specialized microprocessor for processing digital signals, generally used in real-time computing.
*6 Digital Coherent:
A data transmission method that uses the phase and polarization of light to transmit high-capacity signals over long distances due to low signal degradation.
*7 IM-DD:
Abbreviation for Intensity Modulation-Direct Detection (IM-DD); a data transmission/reception system that uses changes in light intensity.
