Allied Telesyn International Corp. this week released media converters aimed at stretching the reach of copper-based Gigabit Ethernet.
The two new media conversion devices could be used to connect a copper-based Gigabit Ethernet switch to a fiber backbone in a large campus by extending the 300-meter limit of copper Gigabit ports up to 10 kilometers.
The two modem-sized devices come with a single 1000Base-T port, and a 1000Base-SX or LX port for converting a single copper Gigabit port into a single- or multi-mode fiber connection. Companies that have fixed-port 1000Base-T switches deployed and want to add long-reach connections to the boxes could save money by using media converters instead of buying new switches with fiber Gigabit uplinks, the company says.
Many companies are adopting copper Gigabit Ethernet technology, which costs a quarter the price of some fiber Gigabit products on a per-port basis. According to the Dell'Oro Group, 1000-Base-T port shipments outgrew fiber-based Gigabit Ethernet port shipments from the second to the third quarter of this year, although copper Gigabit Ethernet ports still only make up 16 percent of the total Gigabit switch market.
The media converters are powered by an external power supply, or can fit into Allied Telesyn's 12-slot, rack-mountable media converter chassis, which can provide power to multiple media converters from a single source.
The AT-MC1004 1000Base-T/1000Base-SX converter is available in the US for US$700, while the AT-MC1005/1, which converts copper Gigabit to multi-mode fiber Gigabit, costs $1,500.
