5x 1G SFP and 4x 10G SFP+ ports plus 1 Gigabit Ethernet port give flexible fiber networking for small offices and ISPs, with fast uplinks and room for legacy devices or backup connections.ARM v7 CPU at 800 MHz with 256 MB RAM and an advanced Marvell switch chip helps keep traffic moving smoothly, supporting efficient high-speed switching and stable network performance.Gigabit Ethernet port is directly connected to the switch chip for full gigabit speed, and PoE-in support adds convenient power options for cleaner installations and fewer cables.Built for reliable fiber connectivity, this indoor switch delivers stable 10 Gigabit links over distances beyond 100 meters, helping reduce data loss, latency, and interference.1U rackmount design with intelligent cooling and hardware-offloaded LAN filtering plus Layer-3 routing makes the CRS310 a practical choice for organized, high-performance network setups.netFiber 9: Trusted FoundationThis powerful switch is perfect for small offices and ISPs looking to improve their high-speed connectivity. Based on the reliable and popular netFiber 9 series, this indoor variant goes a step further. It provides fast and stable 10 Gigabit fiber connections that extend well beyond 100 meters.Unlike standard switches, the MikroTik CRS310 offers various ports, providing you with more ways to connect your network. It comes with five 1G SFP ports for your basic networking needs, alongside four 10G SFP+ ports for tasks that demand the highest data transfer rates. To round off this impressive set, an extra Gigabit Ethernet port gives you even more options, like connecting older systems or having a backup connection.Seamless OperationsAt the core of this device is a cutting-edge ARM v7 CPU with a clock speed of 800 MHz, which is supported by 256 MB of RAM. Whether you're running complex security protocols or managing high-traffic data flows, the CRS310 has got you covered. The real standout feature is its advanced Marvell switch chip, which makes your network faster and more efficient, speeding up data transfers like never before.Its Gigabit Ethernet port is directly connected to the advanced switch-chip: This ensures that the port operates at full gigabit speed, allowing you to use the full potential of your network's bandwidth. You won't experience the frustrating bottlenecks commonly associated with lesser switches, ensuring that your network runs smoothly and at peak efficiency. What's more, the Ethernet port is equipped with Power-over-Ethernet (PoE-in) capabilities.Engineered for Stable NetworkingThe CRS310 uses an intelligent cooling system with a built-in fan controller for heat dissipation. This is particularly valuable during high-traffic scenarios or intense activity, ensuring that the device continues to operate smoothly, extending its lifespan and maintaining great performance.Its 1U rackmount design ensures that you can neatly stack and organize it alongside your other networking hardware, maximizing your use of space. The device comes with robust hardware-offloaded LAN filtering capabilities, not to mention Layer-3 routing features that are also hardware-offloaded.Fiber Optic ReliabilityFiber optic technology significantly lowers data loss, ensuring that your transmissions remain clear over extended distances. This becomes especially critical in environments where you cannot afford even the tiniest degradation in data quality, such as financial transactions or secure communications. Whether you're in a high-stakes online meeting or executing time-sensitive tasks, the reduced latency offered by fiber optics can give you that crucial edge. Lastly, fiber optic connections provide superior protection against various security risks. Unlike copper cables, which can be susceptible to electromagnetic interference, fiber optics are virtually immune to this type of disturbance.
