Applied Optoelectronics is demonstrating its latest transceiver product portfolio at the on-going OFC 19 conference in San Diego, California at booth #2431, from March 5-7.

At the conference, AOI is showcasing its newest 400G datacenter products, including:

• DR4/FR4 400G Transceiver Family: As consumers continue to demand greater bandwidth, the migration from 100G to 400G will be the next vital step in data center architecture. AOI has unveiled its 400G product line with DR4/FR4-type transceivers in both QSFP-DD and OSFP form factors. These 400G transceivers can interconnect between a current 100G network and the next-generation 400G network. Both transceiver families, use four 100G PAM4 optical lanes with a link distance up to 2km. They can be routed to four 100G QSFP28 DR/FR transceivers, allowing data centers to operate with a mixture of 400G and 100G products in the aggregation and core layers within the datacenter. These transceivers are compliant with the IEEE 802.3-2018 and 100G Lambda MSA, both of which are intended for 400G datacenters, Ethernet and cloud networks.
• QSFP-DD form-factor LR8 Transceiver: AOI is presenting the 400G QSFP-DD LR8 transceiver, which can be used for data center applications up to 10km. The 400G LR8 addresses the critical early deployment phase of 400G in datacenters, where there is a need for 400G devices with native 50G per lane data rate. The transceiver combines 8 data lanes with 50 Gbps per lane into a single QSFP module, which is made possible by AOI’s previously-announced 50G PAM-4 directly modulated laser (DML).

In addition to datacenter products, AOI has also announced a new product for use in 5G mobile networks:

• 50 G LR transceiver in QSFP Form-factor: The 50G QSFP28 LR also uses AOI’s high-performance 50G DML PAM4 laser chip, embedded in a high reliability package intended for ruggedized environments often encountered in mobile telecom applications. This product was designed to meet customer requirements for the middle haul and back haul of 5G mobile networks.

At OFC, AOI is also presenting live demonstrations of its latest transceiver product portfolio, including the 400G QSFP-DD DR4, 400G OSFP DR4/FR4, 400G QSFP-DD LR8, 100G QSFP28 DR/FR, and 50G QSFP28 LR transceivers. In addition to the products showcased at the booth, AOI’s Dr. Mingshan Li is presenting a paper entitled “Demonstration of 100 Gbps per Lambda PAM4 Transmission with 1310 nm and 1330 nm Directly Modulated Lasers”. The paper is scheduled to be presented in the “III-IV Lasers” session beginning on March 6.
