Unmanaged Industrial 4-Port 100base-T to 100base-FX Media Converter
This product is an industrial-grade 4-port 100base-T to 100base-FX fiber optic media converter, it's primarily designed for long-distance (20/40/60/80/120 kilometers) transmission in fiber optic networks.
Overview
Features
● This product is specifically designed for demanding industrial environments.
● The device provides 4 100M Ethernet electrical ports, sharing a 100M bandwidth, 1 Console port, and a gigabit fiber optic port.
● The ethernet interface (RJ45 port) supports 10/100M auto-negotiation, full/half-duplex modes, and MDI/MDI-X auto-detection.
● The optical interface supports three fiber optic transmission modes: multi-mode dual fiber, single-mode dual fiber, and single-mode single fiber. SC/ST/FC/LC interfaces are optional.
● It incorporates features such as broadcast storm protection, flow control, collision isolation, error detection, and automatic recovery from deadlocks, making it suitable for high-bandwidth data applications like video transmission.
● The device includes a 512KBits high-speed buffer, preventing video stutter during rapid changes in monitoring scenes.
● It supports the transmission of VLAN oversized data packets, it’s compatible with switch products that support the IEEE802.1Q protocol, and it’s capable of handling Ethernet frames up to a maximum of 1916 bytes.
● It supports a wide range of 9-55V AC/DC power inputs. It features internal isolation and redundant dual power inputs. Power features include overload protection and reverse connection protection.
● It complies with industrial EMC standards.
● It features strong lightning protection, resistance to induced high voltage, and surge protection.
● The design includes fanless cooling for efficient heat dissipation, reducing downtime.
● The housing is made of anodized aluminum alloy with IP40 protection, capable of withstanding harsh environmental conditions.
● It can be mounted on a DIN rail or wall.
● It operates in a wide temperature range from -40°C to +85°C.
● It underwent 100% burn-in testing and comes with a 5-year warranty.
