Mikrotik Cloud Router Switch CRS212-1G-10S-1S+IN: High-Performance Switching and Routing for Modern Fiber Networks

As networking demands increase, the need for a compact, powerful, and flexible solution becomes critical for both enterprise environments and advanced home networks. The Mikrotik Cloud Router Switch CRS212-1G-10S-1S+IN is designed with those exact needs in mind, blending robust Layer 2 switching capabilities with powerful Layer 3 routing features — all within a rack-mountable, fiber-ready form factor.

This model is ideal for setups that require high-bandwidth connectivity and a mix of routing and switching functionality, such as data centers, ISP access points, or corporate backbones. With its 10 SFP ports, one SFP+ port, and one Gigabit Ethernet port, the Cloud Router Switch offers exceptional flexibility for creating dense, high-speed fiber networks without sacrificing manageability or performance.

Dedicated Fiber Connectivity with 10 SFP Ports

At the heart of this Cloud Router Switch is its impressive array of 10 dedicated SFP ports, offering robust fiber connectivity for environments where copper just doesn’t cut it. Whether you’re connecting remote buildings, uplinking to a high-speed core switch, or running long-distance fiber to avoid interference, this switch has you covered.

The inclusion of hot-swappable SFP modules means you can customize each port based on your specific fiber type — single-mode or multi-mode — and transmission distance. This makes the CRS212-1G-10S-1S+IN not just a switch, but a future-proof investment for growing networks.

Future-Ready 10G Connectivity with 1 SFP+ Port

In addition to the 10 standard SFP ports, the Mikrotik Cloud Router Switch also features one SFP+ port, providing 10 Gigabit uplink capacity. This allows you to easily integrate the switch into higher-speed backbones or link it to high-throughput servers for intensive applications like video surveillance, virtualization, or large-scale file transfers.

Having a 10G port in a compact device at this price point gives IT teams a rare combination of performance and value — perfect for evolving infrastructures that need to scale without overspending.

Gigabit LAN Port for Management and Access

Complementing the fiber ports is one Gigabit RJ45 Ethernet port, ideal for management access or integration into copper-based networks. Use it to connect to a traditional router, link to a Wi-Fi access point, or manage the switch via the intuitive Mikrotik RouterOS or SwitchOS platforms.

This port provides the versatility to fit into hybrid networks where both copper and fiber play critical roles.

Layer 2 and Layer 3 Capabilities in One Compact Device

What sets the Cloud Router Switch apart is its dual nature: it combines powerful Layer 2 switching with advanced Layer 3 routing — all in one unit. You get VLAN support, MAC filtering, port mirroring, and broadcast storm control at Layer 2, while enjoying full IP routing, DHCP, static routing, and firewall capabilities at Layer 3.

This makes the switch suitable for environments that need dynamic IP routing between segments but don’t want the hassle (or cost) of managing multiple devices.

Flexible Power Options for Hassle-Free Deployment

The Mikrotik Cloud Router Switch supports multiple power input methods, allowing you to tailor it to your deployment scenario. With support for 8–30V DC power input, you can power it via a wide range of sources, from standard AC adapters to battery backups or solar-powered systems in remote installations.

This flexibility makes it a great option for constrained rack environments, remote telecommunications setups, or mobile network deployments where traditional power sources might not be available.

Rack-Mountable Design for Professional Installations

Space is always at a premium in network closets and data centers. Fortunately, the Cloud Router Switch CRS212-1G-10S-1S+IN is designed for 1U rack mounting, allowing it to fit neatly into standard 19-inch racks alongside your other networking gear.

Its compact form doesn’t sacrifice port availability or performance, making it an excellent choice for setups that require dense fiber connections in a tight footprint.

RouterOS and SwitchOS for Total Control

Like other Mikrotik products, this Cloud Router Switch can run either RouterOS or SwitchOS, depending on your needs. Want granular routing features and a firewall? Go with RouterOS. Need pure switching simplicity? SwitchOS is light and fast.

You can switch between the two operating systems to align with the complexity of your network. Both options offer web-based GUIs, script automation, and full control over configuration, monitoring, and diagnostics.

Use Cases for the Mikrotik Cloud Router Switch

The Cloud Router Switch CRS212-1G-10S-1S+IN is ideal for:

ISPs looking to distribute fiber to subscribers efficiently

Data centers needing compact Layer 3 switch/router solutions

Businesses deploying fiber interconnects between office locations

Surveillance systems requiring high-throughput backbone links

Academic institutions setting up dense, high-speed LANs

Its rich feature set and manageable size make it versatile across industries and applications.

The Smart Choice for Fiber-Centric Networks

Whether you’re upgrading your core, expanding your access network, or building a new fiber infrastructure from scratch, the Mikrotik Cloud Router Switch CRS212-1G-10S-1S+IN delivers the tools you need in a compact, budget-friendly package.

With 10 SFP ports, a 10G SFP+ uplink, Layer 2/3 capabilities, and rack-mountable convenience, this Cloud Router Switch strikes the perfect balance between performance, flexibility, and value. Backed by Mikrotik’s powerful OS options and reliable hardware engineering, it’s a switch that adapts to your network — not the other way around.
