Eoptolink Technology, an advanced optical transceiver solutions provider, uses the OFC 2024 trade show to linear-drive pluggable optics (LPO), operating at 200G per lambda.
LPO transceivers are designed without DSPs or CDRs, resulting in lower power consumption and significantly less latency. Eoptolink 800G OSFP DR4 LPO transceivers utilize a silicon photonics PIC that transmits four parallel channels at 200 Gbps.
Eoptolink said reduced power and latency performance has increased interest in LPO modules for switch-to-server and GPU-to-GPU connectivity in High-Performance Computing applications such as AI and ML clusters.
This demonstration aims to show that LPO and half-retimed solutions are viable alternatives for higher data-rate applications using 200G per lambda.
Additionally, Eoptolink has launched the second generation of its 100G/lane 800G and 400G LPO products for single-mode applications in OSFP, QSFP-DD, and QSFP112 form factors. The second generation of Eoptolink 800G and 400G LPO products enables users to achieve full TP2 compliance at the modules' optical transmit interface. Both gen1 and gen2 LPOs are now available in high-volume production.
Live demonstrations of the LPO transceivers will be conducted, together with 1.6T, 800G, and 50G PON high-performance optical transceiver solutions, at Eoptolink's booth #3127 at OFC 2024, San Diego, CA.
Eoptolink’s demonstration has implications for the broader pluggable optical industry. The company is one of the founding members of the new LPO MSA, which focuses on specifying module and network equipment-level interoperability requirements that span electrical and optical technologies. Starting at 100 Gbps per lane, the LPO MSA will ensure multi-source solutions for a broad ecosystem.
"The exploration of LPOs in NIC and GPU applications are becoming increasingly popular; modern ASICs on the NICs allow full TP2 and TP3 compliance at the optical interface, and at the same time, LPOs offer cost, power and latency advantages", said Sean Davies, VP of Sales for Eoptolink Technology. "Eoptolink is a founding member of the recently launched LPO MSA to help to develop the specifications for networking equipment and optics, which are required to enable a broad ecosystem of interoperable LPO solutions."
