4 Port 10/100/1000 Mbps Gigabit Ethernet Transceiver over Single Fiber

4-Port Gigabit Ethernet over Single Fiber Transceiver

Thor Fiber’s 4-Port Gigabit Ethernet Transceiver transmits five 10/100/1000 Mbps Ethernet channels over a single-mode fiber using WDM technology—one strand, full-duplex.

It allows you to connect multiple Ethernet devices on each end, such as IP cameras, PCs, network switches, Wi-Fi routers, and IP encoders—supporting up to 4 devices per side, making connectivity simple and efficient.

The unit functions as a transparent, unmanaged switch with plug-and-play operation—no configuration required. It uses LC/PC connectors and supports transmission distances up to 20km.

A complete link requires a matched A/B pair (Side A transmits at 1310nm, Side B at 1550nm).

Ideal for industrial, remote monitoring, and transportation applications.

EMI, RFI, and Surge Immunity

Electromagnetic interference (EMI) is common in industrial plants, warehouses, and factory floors. It can corrupt data over copper-based Ethernet links. In contrast, fiber optic transmission is completely immune to EMI, RFI, and ground loop issues ensuring clean, reliable data communication.

By using fiber, you eliminate problems caused by voltage equalization currents and electromagnetic noise, enabling more stable and reliable network performance, especially in electrically noisy environments.
