Description

Breakout DAC cable for 200G aggregation to eight 25G ports over 1 meter. The OSFP host interface splits into 8x SFP28 25GBASE-CR lanes, providing cost-effective, low-latency copper connectivity for server NICs and edge devices. Ideal where 25G access is required from 200G uplinks without optics.

Features

- Economical 200G-to-8x25G breakout for access-layer builds
- Passive twinax copper for minimal latency and power
- Standards-aligned 25GBASE-CR with FEC support
- Plug-and-play OSFP to SFP28 form-factor compatibility
