Alpine Optoelectronics, Inc. used this month’s OFC 2022 to show off its new single-wavelength 100G QSFP28 O-Band xWDM PAM4 optical transceiver. The optical module leverages the company’s patented nCP4 Silicon Photonics Optical Engine.

The 100G QSFP28 supports 16 wavelengths from 1295-1312 nm at 200-GHz spacing aligned to the LAN-WDM grid. The optical transceiver therefore can be sued to support up to 1.6 Tbps of capacity and up to 25-km reach over single-mode fiber without dispersion compensation or amplification. Alpine Optoelectronics says it can produce versions of the transceiver that operate over additional wavelengths and spacing on a custom basis.

The optical transceiver is designed to enable low latency for delay sensitive-applications. Its power consumption and CAUI-4 host interface are compatible with common 100GbE switches, the company adds. Alpine Optoelectronics adds that it also offers a 100G QSFP28 ER Lite version to support single-channel requirements up to 30 km or more.

“Alpine’s new 100G QSFP28 xWDM PAM4 transceiver expands our portfolio of silicon photonics-based transceivers and addresses the need for a straightforward and scalable high-speed, low-cost solution for long- to extended-reach optical interconnects,” said Tongqing Wang, president and CEO of Alpine Optoelectronics. “It provides our partners in data center and wireless markets with another innovative and effective tool to meet their increasingly diverse and cost-sensitive requirements.”
