The D-Link DFE-855MI, often supplied by distributors like Advance Star India, is indeed a versatile 10/100BASE-TX to 100BASE-FX multimode media converter. Consequently, it enables seamless data transmission over longer distances, extending up to 2 kilometers, by utilizing multi-mode fiber with an SC connector.

Furthermore, this compact and reliable device facilitates network expansion without requiring a complete overhaul of existing infrastructure. In fact, it supports auto-negotiation for speed and duplex settings on the twisted-pair (RJ-45) port, thus ensuring optimal performance. Moreover, key features include a 128KB built-in RAM data buffer, auto MDI-MDIX function for straightforward cable connections, and LED indicators for link/activity and duplex status. Therefore, the DFE-855MI stands as a cost-effective solution for extending network reach in various environments, ranging from enterprise and campus networks to industrial applications where reliable long-distance connectivity is crucial.

Additionally, you can seamlessly integrate new fiber technology into existing network infrastructure with the D-Link DFE Series Media Converters to support a wide range of new applications and technologies and, ultimately, future-proof your network. By doing so, you can convert copper connections to fiber optic links, thereby leveraging existing cabling while avoiding costly across-the-board upgrades.

Regarding Copper to Fiber Conversion, the D-Link DFE Media Converters support a large variety of optical fiber types, including multi-mode, single-mode, or single-strand fiber cable. Beyond that, the DFE Series supports a wide range of connection distances to suit the specific needs of Ethernet-to-fiber applications.

Moreover, it boasts a built-in 2-port switch that supports a modified cut-through frame forwarding packet forwarding system. Crucially, it supports bandwidth control and adheres to IEEE802.3u 100BASE-TX, 100BASE-FX (Fast Ethernet, 100Mbps). As mentioned, it has a built-in 128KB RAM data buffer and supports auto MDI-MDIX function. Furthermore, it supports a far end fault function and provides LED displays for link/activity, full/half, and 10/100M status.
