The MikroTik CRS328‑4C‑20S‑4S+RM is a high‑density fiber aggregation switch featuring twenty 1 Gbps SFP ports, four 10 Gbps SFP+ uplinks, and four combo ports that can operate as either Gigabit Ethernet or SFP interfaces. Powered by an 800 MHz dual‑core ARM CPU with 512 MB RAM and the Marvell 98DX3236 switch‑chip, it delivers a non‑blocking throughput of 64 Gbps, 128 Gbps switching capacity, and up to 95.2 Mpps forwarding performance—ideal for ISP distribution, campus backbones, and high‑port‑count optical deployments. The combo‑port group can be software‑selected, allowing administrators to enable any four active interfaces programmatically for maximum flexibility. Its 1U rackmount chassis includes dual redundant 100–240 V AC power supplies with automatic failover, temperature‑controlled cooling fans, and an RJ45 console port for management. Supporting dual‑boot operation between RouterOS and SwOS, extensive Layer‑2 features, VLAN support, ACLs, link aggregation, jumbo frames, and monitoring tools, the CRS328‑4C‑20S‑4S+RM offers a robust, scalable, carrier‑grade switching platform at an exceptional price‑performance level.
