The TP-Link TL-SG3428XF is a JetStream L2+ managed switch designed mainly for fibre-based business networks. It provides 20 Gigabit SFP ports, 4 Gigabit SFP/RJ45 combo ports and 4 10Gbps SFP+ slots for high-speed uplinks or aggregation.

This switch is best used for fibre aggregation, business networks, server rooms, CCTV infrastructure, VLAN-based networks, Omada SDN deployments, linking multiple switches, and connecting devices through SFP fibre modules or compatible copper transceivers.

The TL-SG3428XF has 20 Gigabit SFP ports, 4 Gigabit SFP/RJ45 combo ports and 4 10Gbps SFP+ slots. It also includes RJ45 and micro-USB console ports for management.

The switch has 20 dedicated Gigabit SFP ports plus 4 Gigabit SFP/RJ45 combo ports. The combo ports can be used as either SFP or RJ45, but not both at the same time for the same combo port number.

Combo ports give you a choice between using the SFP fibre slot or the RJ45 copper port for that port number. They are useful when you need a mix of fibre and standard Ethernet connections.

Yes. The switch includes 4 10Gbps SFP+ slots. These are useful for high-speed uplinks to servers, NAS devices, core switches, aggregation switches or other network infrastructure.

The 10G ports are SFP+ slots, not built-in RJ45 10GBase-T ports. To connect copper 10G Ethernet, you would need compatible 10G RJ45 SFP+ transceiver modules, subject to heat, power and compatibility limits.

SFP and SFP+ transceiver modules are normally purchased separately. You need to choose compatible fibre modules, DAC cables or copper SFP+ modules depending on the cable type, distance and network equipment you are connecting.

Yes. TP-Link SFP and SFP+ modules are the safest option for compatibility. Third-party modules may also work in some cases, but compatibility is not guaranteed and should be checked before deployment.

Yes, compatible SFP+ DAC cables can be used for short-distance 10G connections between switches, servers, routers or NAS devices. Always check compatibility with both devices before buying DAC cables.

Yes, compatible RJ45 10G SFP+ modules may be used, but they can run hotter and consume more power than fibre or DAC options. For multiple copper SFP+ modules, check compatibility and allow good airflow.

In many cases, SFP+ slots can work with compatible 1G SFP modules or 1G links, but manual speed configuration may be needed depending on the module and connected device.

This can happen because of module compatibility, cable type, auto-negotiation behaviour, port speed settings, firmware, or the connected device only supporting 1G. Check both devices, update firmware and manually set the port speed if needed.

Yes. It is an L2+ managed switch with advanced configuration options including VLANs, link aggregation, QoS, ACLs, IGMP snooping, static routing, DHCP relay, port mirroring, storm control and centralized Omada management.

L2+ means the switch provides advanced Layer 2 switching features plus selected Layer 3 features such as static routing. It is more capable than an unmanaged switch but is not the same as a full enterprise Layer 3 router or firewall.

Yes. It supports 802.1Q VLANs and multiple VLAN features, making it suitable for separating networks such as staff, guest, CCTV, VoIP, management and server traffic.

Yes, it supports static routing and can route traffic between VLANs in suitable network designs. However, for firewall-style security between VLANs, a proper router or firewall gateway is usually still recommended.

No. It has ACL and security features, but it is not a stateful firewall. If you need advanced security policies, NAT, VPN, WAN routing or stateful inter-VLAN firewall rules, use an Omada gateway, pfSense, OPNsense or another firewall/router.

Yes. The switch integrates with Omada SDN for centralized management, monitoring, batch configuration and cloud-managed network control when used with a compatible Omada Controller setup.

No. The switch can also be managed in standalone mode using web management, CLI, SNMP and other management methods. Omada Controller is useful if you want centralized management across multiple Omada devices.

Yes. When integrated with Omada SDN and a suitable controller, the switch can be centrally managed and monitored with cloud access, depending on your Omada setup.

Yes. It supports standalone management through a web interface. It also supports CLI access through console, Telnet or SSH, plus SNMP and RMON for monitoring.

Yes. The TL-SG3428XF supports static link aggregation and 802.3ad LACP. Link aggregation can combine multiple ports for higher total bandwidth or redundancy when connected to compatible devices.

Yes. It supports STP, RSTP and MSTP, helping prevent network loops and improve redundancy in more advanced switching environments.

Yes. The TL-SG3428XF supports loopback detection and related loop protection features. This is useful in business networks where accidental loops can cause major disruption.

Yes. It supports QoS features including priority queues and traffic prioritisation. QoS is useful for voice, video, CCTV, business applications and latency-sensitive traffic.

Yes. It supports IGMP snooping, which helps manage multicast traffic more efficiently. This is useful for IPTV, multicast video, surveillance and some business network applications.

Yes. The switch includes ACL features that can help control traffic based on defined rules. For complex security between VLANs, it is still best to use a proper router or firewall gateway.

Yes. It supports DHCP relay features, which can help clients in different VLANs or subnets reach a central DHCP server in a managed network design.

Yes. It supports jumbo frames up to 9KB. Jumbo frames can be useful for certain storage, backup and server workloads when all connected devices are configured correctly.

The TL-SG3428XF has a switching capacity of 128Gbps. This helps support high-throughput traffic across its Gigabit SFP and 10G SFP+ ports.

TP-Link lists the packet forwarding rate as 95.23Mpps. This is important for high-traffic business networks and aggregation environments.

No. The TL-SG3428XF is not a PoE switch. It does not provide Power over Ethernet to access points, IP cameras or VoIP phones. If you need PoE, choose a TP-Link Omada PoE switch instead.

Yes, it can carry network traffic for access points, but it does not power them. If your access points require PoE, they need separate PoE injectors or a PoE switch.

Yes, it can be used in CCTV networks, especially where fibre uplinks or VLAN separation are needed. However, it does not provide PoE power to cameras, so PoE cameras need a separate PoE switch or injectors.

Yes. The 10G SFP+ slots make it suitable for connecting NAS devices, servers or other switches at high speed, provided the correct SFP+ modules, DAC cables or network cards are used.

It can be used as a core or aggregation switch in smaller business networks, especially where fibre and 10G uplinks are required. Larger enterprise environments may need higher-end Layer 3 switches depending on design requirements.

Yes, advanced home lab users can use it, especially for fibre, VLANs and 10G uplinks. However, it is more business-focused than a typical home switch, and its fan may not be ideal for quiet rooms.

Yes. TP-Link lists this model with one fan. Because it is an enterprise-style managed switch, it may be more suitable for a rack, network cabinet, comms room or server room than a bedroom or quiet office.

No. It is not a fanless switch. Noise level can vary by environment and workload, but buyers wanting silent operation should consider whether a fanless switch would be more suitable.

Fan modification is not recommended. Removing or changing the fan can cause overheating, errors, reliability issues and may affect warranty. Use the switch in a suitable ventilated rack or cabinet instead.

The TL-SG3428XF uses dual redundant internal power supplies with 100-240V AC input. Redundant power helps improve reliability in business and rack environments.

Dual redundant PSU means the switch includes two power supply units so the switch can continue operating if one power source or PSU fails, depending on how the power feeds are connected.

Yes. The TL-SG3428XF is rackmountable and is designed for installation in a standard network rack or cabinet.

TP-Link lists the dimensions as 440 x 220 x 44mm. This is a standard 1U rack-style switch size suitable for rackmount installation.

TP-Link lists maximum power consumption as 35.7W at 110V/60Hz. Actual power use depends on installed modules, workload and operating conditions.

Yes. With many Gigabit SFP ports, the switch can be used in fibre-to-desk or fibre aggregation designs where clients, switches or media converters connect using fibre modules.

Check whether you need SFP fibre ports rather than RJ45 copper ports, whether you need PoE, which SFP/SFP+ modules or DAC cables you require, your VLAN and routing needs, rack space, fan noise tolerance and Omada Controller compatibility.

This switch is not ideal for users who only need simple plug-and-play Ethernet, silent fanless operation, built-in PoE, mostly RJ45 copper ports, Wi-Fi router features, or a full stateful firewall. It is best for business users, IT installers and advanced networks needing managed fibre SFP aggregation with 10G SFP+ uplinks.
