MikroTik CRS112-8P-4S-IN 8-Port Gigabit PoE Switch with 4 SFP

The MikroTik CRS112-8P-4S-IN is a managed gigabit network switch combining eight PoE-capable RJ45 ports with four SFP uplink ports, making it a compact but capable backbone for both wired and fiber-connected networks.

Flexible Power Delivery and Fiber Uplinks in One Unit

• 8 × Gigabit Ethernet ports (10/100/1000 Mbps) for full-speed wired connections to workstations, access points, and IP cameras
• PoE output on all 8 RJ45 ports — supports 802.3af/at auto-sensing PoE/PoE+ as well as Passive PoE, removing the need for separate power injectors
• 4 × SFP ports enable fiber uplinks at up to 1 Gbps, ideal for connecting to a core switch or extending runs beyond copper distance limits
• 12 independent switching ports in total for reliable, low-latency traffic segmentation
• Secondary DC input on the rear supports 48–57 V for full 802.3af/at PoE operation

Well suited for small business offices, security camera deployments, wireless access point distribution, and any environment where both PoE device powering and fiber uplink flexibility are needed from a single switch.
