800G OSFP112DD MMF MPO 850nm
Price: Rs 0.00
Product Overview
The 800G OSFP112DD SR8 transceiver is an advanced parallel-optics module designed for ultra-high-density data center links.
It supports 8×100 Gbps PAM4 channels in each direction, offering a total bandwidth of 800 Gbps over OM4 multimode fiber.
Based on the OSFP112 Double-Density (DD) platform, it delivers outstanding electrical performance, efficient heat dissipation, and full CMIS management compatibility.
This module is ideal for short-reach interconnects between switches, routers, and AI/ML clusters where bandwidth and density are critical.
