Description

Very short reach 800G OSFP breakout transceiver offering two independent 400G DR4 links for top-of-rack and adjacent-rack connections up to 50 m. Parallel 1310 nm operation over MPO-12 simplifies high-density, short-hop fabrics.

Features

- Cost-effective very short reach breakout (2x400G DR4)
- High-density parallel SMF with dual MPO-12
- Hot-swappable with integrated digital diagnostics
- Standards-based DR4 for multi-vendor optical interoperability
- Optimized for TOR/leaf adjacency and short intra-row links
