The CX4800-56F switch from Zyxel Networks is designed for high-demand network environments, providing essential 100GbE connectivity. In 2025, 100 gigabit ethernet, previously reserved for leading carriers, is becoming a staple in enterprise networking—crucial for accommodating expanding data requirements in data centers driven by cloud computing and AI. A recent IDC report highlighted that 100 GbE switches represented 46.3% of the data center market’s ethernet switch revenue last year.
Zyxel has broadened its enterprise offerings with the introduction of the CX4800-56F, a Layer 3 managed switch, building on the capabilities of their earlier XGS4600-52F model, which featured 10G uplinks. This switch takes a leap forward, providing a combination of 10G and 25G ports alongside 100G uplinks.
According to Tri Nguyen, Zyxel’s channel sales and product manager, “This is our first switch of this size, but not the first of the class.” The new architecture is powered by a 2.20 GHz Intel CPU running Zyxel’s ZyNOS operating system, which features a command-line interface designed for administrators familiar with Cisco environments. Notably, Zyxel’s offerings currently do not include support for open-source network operating systems like SONiC.
The technical specifications of the CX4800-56F reveal its capacity to handle substantial switching demand, with a total switching capacity of 4.0 Tbps and forwarding rates of 2.0 Bpps (billion packets per second). The non-blocking architecture allows all ports to maintain full wire-speed throughput, even under maximum traffic conditions. The switch is equipped with:
- 48 SFP28 ports for 10GbE/25GbE connectivity
- 8 QSFP28 ports for 100GbE connections
- A console port for direct management access
It also supports Layer 3 routing with advanced features like access control lists and VLAN segmentation, as well as IEEE 802.3ad link aggregation for enhanced throughput and redundancy.
Target applications for the CX4800-56F include service providers and extensive network deployments requiring high-capacity backbone connections for 10G access layers. As Nguyen elaborates, the switch is particularly useful in environments supported by emerging technologies like Wi-Fi 7.
For management, the switch utilizes Zyxel’s NebulaFlex Pro technology, allowing for both standalone and cloud management through the Nebula Control Center (NCC). An included one-year professional pack license facilitates IGMP technology and comprehensive network analytics.
One of the standout features of the CX4800-56F is its support for networked AV mode, which simplifies the management of audio/visual systems over IP. Zyxel claims this mode enables latency-free 4K video streaming on a 10GbE network and introduces AI functionalities that enhance reliability by automatically rerouting paths to optimize service quality.
