Product Overview

The TBC-FP4148N-4PF is a high-density unmanaged Passive PoE switch, equipped with 48 × 10/100Mbps Ethernet ports, 2 × Gigabit RJ45 uplink ports, and 2 × Gigabit SFP fiber uplink ports for flexible network deployment. Ports 1–48 support 15V Passive PoE output, delivering up to 30W per port, with a maximum total PoE power budget of 600W. As a non-standard Passive PoE switch, this device is designed for use with compatible Passive PoE powered devices, such as wireless bridges, video intercom systems, and other low-voltage network equipment. For devices that do not natively support Passive PoE, a compatible PoE splitter is required for voltage conversion.To ensure proper power delivery, straight-through RJ45 Ethernet cables must be used. Crossover or non-standard cable wiring may prevent connected devices from powering on correctly.

This switch is ideal for network environments requiring high-density PoE deployment and is widely used in smart buildings, intelligent low-voltage systems, security monitoring, and other cost-effective digital transmission applications.

With its unmanaged plug-and-play design, the switch requires no configuration, enabling quick installation and easy operation.
