Product Information

Overview

The MikroTik CRS328-4C-20S-4S+RM is a fiber aggregation switch designed for ISP, enterprise, and lab networks. Twenty dedicated Gigabit SFP ports, four 10G SFP+ uplinks, and four Gigabit SFP/RJ45 combo ports provide flexible connectivity for consolidating fiber connections and linking access switches to distribution infrastructure.

Each combo port supports either its SFP or RJ45 connection, providing 28 independent ports in total. Software-selectable combo interfaces allow administrators to choose the active connection to suit the installation. The switch delivers 64 Gbps of non-blocking throughput and 128 Gbps of switching capacity.

Dual-boot support lets administrators choose SwOS for dedicated switching management or RouterOS for additional routing and network configuration capabilities. A 1U rackmount enclosure, dual AC power supplies with failover, and an RJ45 serial console support deployment and maintenance in network racks. SFP and SFP+ modules are sold separately.

Ideal Applications

  • Gigabit fiber aggregation in ISP and enterprise networks
  • Distribution switching with 10G uplinks
  • Mixed copper and fiber installations requiring flexible port selection
  • Connecting fiber-based access switches across buildings
  • Network labs requiring RouterOS or SwOS management

Highlights

Key Features

High-Density Fiber Connectivity

Twenty dedicated Gigabit SFP ports and four 10G SFP+ uplinks consolidate fiber connections in a single 1U switch, supporting access aggregation and high-speed connections to distribution equipment.

Flexible SFP/RJ45 Combo Ports

Four Gigabit combo ports support either SFP or RJ45 connectivity. Each pair functions as one active port, with software selection providing flexibility for mixed copper and fiber deployments.

RouterOS or SwOS Management

Dual-boot support provides a choice of SwOS for switch-focused management or RouterOS for additional routing and network configuration features. VLANs, traffic monitoring, access controls, and link aggregation support managed network deployments.

Redundant Power and Rackmount Design

Dual 100–240 V AC power supplies provide power failover in a compact 1U enclosure. An RJ45 serial console and configurable mode button provide additional management and troubleshooting options.
