Anritsu Firm (President Hirokazu Hamada) has started product sales from July 24 of its 120 Gbaud Wideband Linear Amplifier*1 AH15199A developed to guage 120 Gbaud PAM4*2 items utilized by next-generation Ethernet 800GbE/1.6TbE interfaces.
This new amplifier encompasses a wideband frequency response of 105 GHz at a –3 dB bandwidth and may amplify 120 Gbaud PAM4 alerts to 2.0 Vpp.
The excessive achieve*3 of +16 dB and low jitter*4 of 500 fs allow amplification of attenuated alerts on transmission traces with high-quality waveforms.
Moreover, when used as an 800GbE/1.6TbE digital coherent*5 and IM-DD*6 optical modulator driver, it could possibly amplify 120 Gbaud PAM4 alerts from numerous sign sources, comparable to DSP*7, and may immediately drive modulators and different units requiring excessive amplitude.
By promoting this wideband linear amplifier, Anritsu is assembly its clients’ wants and contributing to the growth and easy operation of high-speed networks.
Growth Background
Cell knowledge visitors is rising with the expansion of 5G and different providers, however additional will increase in communication speeds for servers and community units are a serious concern.
The following-generation Ethernet customary for 800GbE/1.6TbE high-speed networking will use PAM4, which will increase the transmission capability per unit time to 120 Gbaud utilizing 2-bit (4-value) alerts. Then again, since increased communication speeds undergo increased sign attenuation, a linear driver is required to faithfully amplify the PAM4 sign.
Product Define
The AH15199A is a high-power linear amplifier supporting 2.0 Vpp sign analysis with 120 Gbaud PAM4 to realize high-speed, high-power (2 Vpp) knowledge transmission at a 120 Gbaud fee with a low energy consumption of lower than 1.2 W.
The usual devoted energy provide, downsized to 1/nineteenth, reduces the chance of harm from improper dealing with.
Goal Markets
Optical/electrical high-speed machine producers, measuring devices for optical sign testing
Functions
Analysis of high-speed 120 Gbaud optical units
