Applied Optoelectronics demonstrating new transceiver product portfolio at OFC

Applied Optoelectronics Inc (AOI) of Sugar Land, TX, USA – a designer and manufacturer of optical components, modules and equipment for fiber access networks in the Internet data-center, cable TV broadband, fiber-to-the-home (FTTH) and telecom markets – is demonstrating its latest transceiver product portfolio in booth #2431 at the Optical Fiber Communications (OFC) conference in San Diego, CA, USA (5-7 March).

In particular, AOI is showcasing its latest 400G data-center products, including:

  • DR4/FR4 400G transceiver family. With the migration from 100G to 400G to be the next vital step in data-center architecture as consumers continue to demand greater bandwidth, AOI is unveiling its 400G product line with DR4/FR4-type transceivers in both QSFP-DD and OSFP form factors. The 400G transceivers can interconnect between an existing 100G network and a next-generation 400G network. Both transceiver families use four 100G 4-level pulse amplitude modulation (PAM-4) 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 data center. The transceivers are compliant with the IEEE 802.3-2018 and 100G Lambda MSA (multi-source agreement), both of which are intended for 400G data-center, 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. It addresses the critical early deployment phase of 400G in data centers, where there is a need for 400G devices with native 50G per lane datarate. The transceiver combines 8 data lanes with 50Gbps per lane into a single QSFP module, which is made possible by AOI’s existing 50G PAM-4 directly modulated laser (DML).

AOI is also announcing a new product for use in 5G mobile networks:

  • 50G LR transceiver in QSFP form-factor. The 50G QSFP28 LR also uses AOI’s high-performance 50G DML PAM-4 laser chip, embedded in a high-reliability package intended for ruggedized environments often encountered in mobile telecom applications. This product was designed to meet requirements for the middle haul and back haul of 5G mobile networks.

At OFC, AOI is giving 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, AOI’s Dr Mingshan Li is presenting a paper ‘Demonstration of 100Gbps per Lambda PAM4 Transmission with 1310nm and 1330nm Directly Modulated Lasers’ in the ‘III-IV Lasers’ session on 6 March (2pm).
