Media Converter

What is Media Converter A media converter is a device which converts signals it receives from one media type to signals appropriate to another media type.

Distances Over copper cabling distances are limited to 100m (330ft) between any two active devices and network perimeter (by using repeaters) can not exceed 205m (660ft) for 100mbps or double for 10mbps. By using optical fibers, distances between active devices may be extended to 2000m (6500ft) for 10mbps (even more in full duplex mode) and up to 2000m for 100mbps. By using single mode fibers (and proper interfaces) distances of tens of km may be obtained.

This is the classic fiber optic cabling and is far and away the most prevalent fiber type in use today inside buildings. It is the fiber type the IEEE, ANSI, TIA, and ISO standards organizations typically define in fiber LAN specifications. Fiber Type (Multi-Mode) 62.5/125 µm, 50/125 µm Multiple light paths Relatively inexpensive Modal-bandwidth limited Primarily used for LANs

For more demanding applications a second fiber cable type “single-mode” is available. Single-mode fiber uses a smaller core diameter, between 8 and 12 µm (8 - 9 being the average), with the same cladding diameter as multi-mode. Fiber Type (Single-Mode) 8-9/125 µm Single light path Somewhat more costly More difficult to terminate Essentially unlimited bandwidth Primarily used for MAN/WANs

850 nm multi-mode: Standard for 10Base-FL 10 Mbps Ethernet and 100Base-SX 100 Mbps Short Wavelength Ethernet. Also used for 1000Base-SX Gigabit Ethernet nm multi-mode: Standard for 100Base-FX 100 Mbps Ethernet. Also used by other high-speed LAN protocols such as FDDI, ATM/OC-3, etc nm single-mode: Standard for 1000Base-LX Gigabit Ethernet. Also commonly used for applications where greater distance is required than can be achieved with multi-mode fiber nm single-mode: Not an Ethernet standard, but used extensively for long-haul telecommunications at speeds of up to 40 Gbps (OC-768) and for all Dense Wavelength Division Multiplexing (DWDM) applications.
