D-Link DMC-905 – 10G Ethernet Media Converter with 10G/5G/2.5G/1G RJ-45 Port & 10GBASE-X SFP+ Slot
Overview:
• The D-Link DMC-905 is a 10G Ethernet Media Converter designed to convert high-speed copper Ethernet connections to 10G fiber optic links.
• It provides one multi-gigabit RJ-45 port supporting 10G / 5G / 2.5G / 1G speeds and one 10GBASE-X SFP+ port for fiber uplink connectivity.
• The media converter helps extend high-bandwidth network connections beyond copper distance limitations using compatible SFP+ transceivers.
• It supports modern Ethernet standards including 10GBASE-T, 2.5G/5GBASE-T, 1000BASE-T, 10Gbps Ethernet, and full-duplex flow control.
• Auto-MDI/MDIX support simplifies installation by automatically detecting cable type.
• Store-and-forward transmission and full wire-speed forwarding help maintain stable and reliable data transmission.
• The compact standalone design makes it suitable for network upgrades, fiber backbone extensions, and high-speed connectivity between switches, servers, and remote network devices.
