Industrial Gigabit Ethernet Copper to Fiber Media Converter
This product is an industrial-grade fiber media converter, it's designed for media conversion or extension of network transmission between 1 port of 10/100/1000Base-T twisted pair and 1000Base-FX fiber optic media.
Overview
Features
● The device is specifically designed for harsh industrial environments.
● It provides 1 Gigabit Ethernet port and 1 Gigabit optical port.
● The ethernet port (RJ45) supports 100/1000Mbps auto-negotiation, full/half duplex mode, and automatic MDI/MDI-X detection.
● The fiber interface supports multi-mode dual-fiber, single-mode dual-fiber, and single-mode single-fiber transmission modes, with optional SC/ST/FC/LC interfaces.
● It features functions such as broadcast storm protection, flow control, collision isolation, error detection, and auto-reset in case of system freeze, making it suitable for high-bandwidth data applications such as video transmission.
● The device has a built-in 1MBits high-speed buffer to prevent video transmission lag in rapidly changing monitoring scenes.
● It supports the transmission of VLAN jumbo frames and can be used with switches that support the IEEE 802.1Q protocol, supporting Ethernet frames up to 9K bytes.
● The optional Console port allows for reading the device status and configuring its parameters.
● It supports internal isolation and redundant dual power inputs.
● It supports a wide range of 9-55V AC/DC power input.
● The power supply has overload protection and reverse connection protection.
● It complies with industrial-grade electromagnetic compatibility requirements.
● It has strong lightning protection capabilities, with resistance to lightning strikes, high voltage induction, and surge protection.
● The device is housed in an anodized aluminum alloy enclosure with an IP40 protection rating, capable of withstanding harsh environmental conditions.
● It can be mounted on a DIN rail or wall-mounted.
● Wide temperature range: operating temperature from -40°C to +85°C.
● The device undergoes 100% burn-in testing, with a warranty period of 5 years.
