D-Link 100/1000 Mbps to SFP Industrial Media Converter with -40 to 70 °C operating range

The D-Link DIS-M100G-SW is an industrial Gigabit unmanaged media converter that converts Ethernet signals to fiber, enabling long-distance, high-speed connectivity. Housed in an IP30-rated metal casing with a fanless design, the unit operates in extreme temperatures from -40 °C to 70 °C and supports dual power input for redundant power configurations. Its compact dimensions allow mounting on a DIN rail or a flat surface, making it suitable for space-constrained telecom cabinets and distribution boxes.

Advantages

The DIS-M100G-SW provides flexible fiber connectivity with support for both single-mode and multi-mode SFP modules and compatibility with IEEE 802.3u/x/ab standards. Auto-Negotiation and Auto-MDI/MDIX simplify installation by ensuring correct link speeds and polarity without manual configuration. The fanless metal enclosure and IP30 protection increase durability in harsh environments while low power consumption and dual power inputs offer reliable, continuous operation.

How to use

Install the DIS-M100G-SW on a DIN rail or mount it on a flat surface using the provided brackets. Insert an appropriate SFP module for single-mode or multi-mode fiber into the SFP slot and connect the fiber cable. Connect the Ethernet device to the RJ-45 port. Apply DC power to one or both power inputs for normal or redundant operation. The converter is unmanaged and supports plug-and-play operation—Auto-Negotiation and Auto-MDI/MDIX handle link configuration automatically.

Recommendations

Use compatible SFP modules and fiber cable types (single-mode or multi-mode) to match required link distances, and ensure the power source meets the 12–48 V DC input specification. For installations in harsh or dusty environments, verify that enclosure mounting and cable entry provide adequate protection despite the IP30 rating.
