AMG extends Ethernet services to 250 metres


UK networking and transmission specialist AMG Systems has come up with an innovative answer to the limitations of conventional Ethernet services – industrial semi-managed switches with the capability to extend Ethernet and Power over Ethernet delivery to 250m.

“AMG’s semi-managed switches have an extended operation feature which provides them with the ability to provide systems with Ethernet, including PoE/PoE+, at distances of up to 250m. The switches operate on a per copper port basis at a fixed 10Mbps duplex, and they can support up to 30W PoE+ power output. And because they’re optimised for use with IP CCTV video, this makes the switches of great value to remote and demanding security surveillance installations”, says AMG Sales and Technical Support Manager Ian Creary.

“The switches are really valuable in those instances where it’s not possible or feasible to incorporate additional Ethernet extenders, or to use additional fibre cable,” he says. “So for instance in an agricultural environment, or a very large car park, it might not be possible to provide additional power. But we can extend the Ethernet capabilities of the existing conventional copper cabling by 150% using these switches.”

A further advantage is that the semi-managed switches can be daisy-chained effectively even when cameras are multicasting, because data is only sent via the switch’s uplink, rather than via all copper ports as on an unmanaged switch. This helps to prevent data flooding and storms which can cripple a network. And because they are semi-managed, no programming, configuration or setup is required, which makes them quick to install and simple to maintain.

The switches are available in 100Mbps fast Ethernet (AMG9HMS-SF) or Gigabit (AMG9HMS-SG) versions, and as part of AMG’s industrial range they have been designed to deliver high performance even in the harshest of environments, operating in temperatures ranging from minus 40 deg Centigrade to 75 deg Centigrade
