8-Port 10/100base-T Industrial Fiber Media Converter
This device is an industrial-grade 8-port 10/100base-T to 100base-FX fiber converter designed for long-distance (20/40/60/80/120 kilometers) fiber network transmission.
Overview
Features
● The device features an IP40 protection level, capable of withstanding harsh environmental conditions.
● It provides 8 100Mbps Ethernet ports and 1 100Mbps fiber port, sharing a 100Mbps bandwidth. It supports distances of 20km, 40km, 60km, 80km, and 120km for the fiber port.
● It supports the transmission of VLAN jumbo frames and can be used with switches that support the IEEE 802.1Q protocol.
● The ethernet interface (RJ45) supports 10/100Mbps auto-negotiation, full/half duplex mode, and MDI/MDI-X auto-detection.
● It has functions such as broadcast storm protection, flow control, collision isolation, error detection, and automatic reset in case of system freeze. It is suitable for high-bandwidth data applications such as video transmission.
● The power supply has strong lightning protection capabilities, including resistance against lightning strikes, high voltage induction, and surge protection. The fanless design ensures efficient heat dissipation and reduces repair time.
● When dual DC power supply (5.08 terminal block):
● It can be powered by a DC 9-55V or AC 7-50V wide-range power supply. The power supply has automatic polarity detection, eliminating the need to distinguish between positive and negative poles during installation.
● It supports internal isolation, redundant dual power inputs, and reverse connection protection.
● When AC power supply (3-pin AC socket):
● It supports AC85-265V input or DC110-300V wide-range input.
● DIN 35mm rail mounting or wall-mounted.
● Working temperature 40 ℃ ~ + 85 ℃.
● The device has passed the 100% burn-in testing.
● Warranty period: 5 years.
