Why choose it

Dual-rate flexibility lets you upgrade from 10G to 25G without replacing cabling or optics. Digital diagnostics monitoring provides real-time visibility into transceiver health, while low power consumption reduces thermal load in dense racks. Compatibility with Cisco and MSA-compliant equipment ensures seamless integration into existing infrastructure.

Ideal use cases

• Data center interconnect between top-of-rack and aggregation switches
• Enterprise campus backbone links over multimode fiber
• Upgrading 10G links to 25G while preserving OM3/OM4 cabling
• High-density server access with hot-swappable optics

Good to know

The module operates from a 3.3V supply and is hot-swappable, allowing replacement without network downtime. It complies with IEEE 802.3by and 802.3ae standards, ensuring interoperability with industry-standard equipment.
