Product Overview
The GQ-IF12 series is an Ethernet converter that interfaces between electrical and optical ports. It features two 10/100 Mbps Ethernet electrical ports and one 100 Mbps optical port. This device is designed for industrial environments, enabling interconnection among multiple motherboard servers, repeaters, hubs, terminal devices, and additional terminals. The optical port extends Ethernet transmission distances from 100 meters over copper cabling to 2 kilometers (using multimode fiber) or 120 kilometers (using single-mode fiber). The unit is housed in a DIN‑rail‑mountable aluminum enclosure with passive cooling, accepts DC power input, offers IP40 protection, and operates within a wide temperature range of –40°C to +75°C, ensuring long-term, stable, reliable, and safe performance even under harsh conditions such as extreme heat, cold, dust, and electromagnetic interference.
It is suitable for industrial control automation applications such as road traffic management, rail transit, power automation, coal‑mine automation, wind energy and wind power, metallurgical steel plants, oil and gas, building automation systems, oilfield control automation, hydropower plant control automation, data center monitoring systems, water‑resources monitoring, environmental protection monitoring, urban underground utility tunnels, and other industrial settings that require high‑performance, highly reliable network environments.
Product Features
◆ Supports one 100-Mbps optical port and two 100-Mbps electrical ports; the ports support auto‑MDI/MDI‑X.
◆ Supports full-duplex and half-duplex auto-negotiation.
◆ All ports support wire-speed forwarding, ensuring non-blocking packet forwarding.
◆ Complies with IEEE 802.3/802.3u/802.3x store-and-forward mode.
◆ Dual-power DC 9–48 V redundant input
◆ Supports full-load operation across a temperature range of -40 to 75°C.
◆ Aluminum profile enclosure, DIN rail mounting, IP40 protection rating
◆ Low-power, fanless design
◆ The circuit board supports triple‑protection treatments—mold resistance, moisture resistance, and salt‑spray resistance (optional).
