RAD ASMi-52L/ETH/2W Ethernet 2-Wire SHDSL Modem / Multiplexer
The ASMi-52L/ETH/2W is a compact SHDSL modem designed to extend a single Ethernet service over a single 2-wire copper pair. It enables reliable Layer 2 connectivity where fibre infrastructure is unavailable or impractical, making it suitable for defence networks, utilities, transport systems, industrial facilities and campus environments.
Using SHDSL technology, the unit delivers symmetrical data transmission with configurable line rates to suit loop conditions. A single 10/100Base-T Ethernet interface provides transparent bridging for IP devices and remote LAN extension over existing copper infrastructure.
This model is ideal for cost-effective Ethernet backhaul where only one copper pair is available.
