The MikroTik CRS317 is a high-density 16-port 10G SFP+ Cloud Router Switch built for fiber aggregation in ISP, enterprise, and data center networks. It delivers wire-speed Layer 2 switching across all SFP+ ports while offering the flexibility to run either RouterOS or SwOS, depending on your network requirements.

Where the CRS317 is commonly used

• ISP core and aggregation switching
• Enterprise and data center fiber distribution
• High-density 10G lab and test environments
• Networks requiring silent operation and redundant power

Powered by a next-generation switching chip, the CRS317 delivers non-blocking wire-speed performance on all sixteen 10GbE SFP+ ports with any Ethernet frame size. Hardware-based features such as Spanning Tree Protocol and Link Aggregation (LACP) provide stability and redundancy for demanding network environments.

The CRS317 features dual redundant power supplies and a passive cooling design for completely silent operation. In higher-temperature environments, two integrated fans activate automatically to maintain safe operating temperatures without compromising reliability.
