The Optical Transceiver 800G OSFP Flat (Close Top) 2×DR4+ SiPh is engineered to deliver high-performance, longer-reach optical connectivity for AI-driven and hyperscale data center environments. Supporting eight 106.25Gbps channels, this transceiver enables reliable 800G Ethernet and InfiniBand transmission over single-mode fiber up to 2 km using advanced DR4+ parallel optics.
Built on silicon photonics technology with PIN receivers, the module provides strong signal integrity, low insertion loss, and stable optical performance across extended reach links. Featuring dual MPO-12 connectors, it supports two independent DR4+ optical interfaces, enabling scalable and flexible high-density network architectures. The OSFP Flat (Close Top) form factor is optimized for systems with tighter mechanical or airflow constraints, while commercial temperature operation and a maximum power consumption of 15W make this transceiver well suited for production-ready AI clusters and modern data center infrastructures.
