Product Overview

The TBC-S5148U-4PF is a full Gigabit fiber switch independently developed and designed by Tianbo Communication. It adopts a high-performance Gigabit Ethernet switching chipset and a high switching capacity architecture, delivering fast data processing and smooth data transmission. The switch features 48 RJ45 ports, 2 × 10/100/1000BASE-T auto-negotiation RJ45 Gigabit uplink ports, and 2 × 1000BASE-X SFP uplink ports, supporting high-speed Gigabit data transmission and fiber uplink connectivity. It complies with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3z, and IEEE 802.3x standards. With a store-and-forward switching mechanism, it provides a 104Gbps switching capacity and a 77.38Mpps packet forwarding rate, and supports auto-negotiation, full/half duplex auto-sensing, and Auto MDI/MDIX. Featuring a standard 1U rack-mount design, steel alloy housing, and built-in power supply, the switch is suitable for enterprise networks, campus networks, video surveillance, and other high-density Gigabit network applications.

Key Features

48 Gigabit Access Ports for High-Density Network Deployment

• Features 48 × 10/100/1000BASE-T Auto-Negotiation RJ45 ports, supporting high-speed Gigabit data transmission and high-density connectivity for multiple network terminals.

• Equipped with 2 × 10/100/1000BASE-T Auto-Negotiation RJ45 uplink ports and 2 × 1000BASE-X SFP dedicated fiber ports, supporting flexible copper and fiber uplink connectivity for different network architectures.

• All RJ45 ports support Auto MDI/MDIX and auto-negotiation, as well as IEEE 802.3x full-duplex Flow Control and Backpressure half-duplex Flow Control, improving network communication stability.

High-Performance Switching for High-Speed Data Transmission

• Provides a 104Gbps switching capacity and a 77.38Mpps packet forwarding rate, supporting efficient data switching and line-rate forwarding for high-density Gigabit networks.

• Adopts a store-and-forward switching mechanism, fully receiving and forwarding data packets to improve transmission stability and reliability.

Multiple Operating Modes for Flexible Network Deployment

• Standard Switching Mode — All ports can communicate freely with each other, suitable for general data transmission environments.

• VLAN Isolation Mode — Isolates data communication between access ports, suppresses broadcast traffic, and improves network performance and data transmission security.

• VLAN Switch Operation: 
When the switch is OFF, ports 1–48 can communicate with each other.
When the switch is ON, ports 1–48 are isolated from each other and can communicate only with RJ45 uplink ports 49 and 50, and SFP1 and SFP2 ports.

Reliable Design for Stable Long-Term Operation

• Features a high-reliability hardware design and built-in power supply, providing stable data switching performance for continuous long-term operation.

• Features a durable steel alloy housing and standard 1U rack-mount design, allowing convenient installation in standard 19-inch network cabinets and making it suitable for centralized deployment in server rooms and network centers.

Plug-and-Play for Easy Deployment

• Requires no complex configuration. Simply connect the power supply and network cables for operation, supporting various network terminals and simplifying network deployment and maintenance.

• Supports 10/100/1000Mbps auto-negotiation, automatically matching the network speed according to the connected device for flexible network deployment.

• Suitable for building high-density Gigabit networks in enterprises, government offices, hotels, shopping malls, campuses, hospitals, and small- to medium-sized businesses.
