Applied Optoelectronics Announces 100 Gbps per Lambda PAM4 Directly Modulated Lasers
November 13 2017 - 8:30AM
Applied Optoelectronics, Inc. (Nasdaq:AAOI), a leading provider of
fiber-optic access network products for the internet datacenter,
cable broadband, fiber-to-the-home and telecom markets, announced
the development of uncooled 100 Gigabits per second (Gbps) per
lambda PAM4 directly modulated lasers (DMLs) for 400 Gbps optical
transceivers.
Transceivers based on DMLs are preferred in datacenter
applications due to their low power consumption and low cost,
compared with solutions based on silicon and other external
modulators. The 1310nm 53 Gbaud PAM4 100 Gbps per wavelength lasers
leverage AOI’s mature high volume 25 Gbps DML product platform,
which was further optimized to achieve a high laser bandwidth of
nearly 30 GHz. At 100 Gbps, the newly developed lasers exhibit PAM4
eyes with a transmitter dispersion eye closure quaternary (TDECQ)
value of 2.5dB, along with other performance metrics that make them
suitable for use in 400G DR4, 400G FR4, and 100G DR1 transceivers
that meet the IEEE 802.3 Ethernet transceiver standards.
“100 Gbps directly modulated lasers are the key to next
generation 400G products for datacenter applications. By building
on our current PAM4 DML platform development, we are now able to
achieve 100 Gbps per lane. We believe that this solution is the
best technical approach to extend the cost leadership AOI has
engineered at 40G and 100G to 400G and beyond,” commented by Dr.
Jun Zheng, Applied Optoelectronics, Inc. vice president of
R&D.
