Description

High-density breakout DAC for 400G aggregation to eight 50G ports over 2 meters. OSFP host interface splits into 8x SFP56 50GBASE-CR lanes, delivering low-latency, low-power copper connectivity for server access and leaf breakout links. Ideal where short to medium rack-to-rack runs are needed without optical transceivers.

Features

- Cost-effective 400G-to-8x50G copper breakout
- Passive twinax design for minimal latency and power
- Reliable 2 m reach for short intra-rack or adjacent rack links
- Standards-based 50GBASE-CR with RS-FEC
- Quick deployment with fixed connectors (OSFP to SFP56)
