Overview
The ATOP 1.6T OSFP224 2xFR4 is an ultra-high-bandwidth optical transceiver built for next-generation AI clusters and hyperscale data center networks. It aggregates 1.6 Tbps across eight 212.5 Gbps channels and operates over CWDM wavelengths from 1271 to 1331 nm, supporting transmission distances up to 2 km over single-mode fiber.
Using advanced silicon photonics with PIN receivers and dual duplex LC connectors, the module is offered in flat-top and closed-top OSFP form factors for optimized thermal performance in high-density deployments. At a maximum 25 W power consumption it is well suited to production AI and data center environments requiring high bandwidth density and signal integrity.
Key Benefits
Longer reach: 2 km over SMF for row-to-row and switch-to-switch links. CWDM SiPh design: PIN-based silicon photonics for reliability. Thermal flexibility: flat-top and closed-top form factors.
Applications
AI and ML cluster interconnect, hyperscale data center networks, 1.6T Ethernet and InfiniBand topologies, 2 km intra-data-center reach.
