RAD ASM-61 2-Wire Symmetrical VDSL Modem

ASM-61/AC/CO  ASM-61/AC/CPE
ASM-61/DC/CO  ASM-61/DC/CPE
 

Features
 Data rate of 10 Mbps
 Range of up to 1 km (0.6 miles) over 24 AWG cable
 User interface is a built-in 10/100BaseT Ethernet bridge
 Plug-and-play operation
A complete solution for high speed services over existing  copper lines, the ASM-61 provides full duplex, symmetrical 10 Mbps Ethernet traffic over 2-wire 24 AWG (0.5 mm) copper cable, for distances of up to 1 km (0.6 miles).

The ASM-61 extends the range of internal LANs using VDSL technology, based on ETSI QAM line coding requirements for the physical medium.

The ASM- 61 compensates for line impairments and mixed cabling by using advanced equalization, adaptive filtering and echo cancellation technology.


An internal clock is available. In this mode, the internal clock generator provides the clock for the digital interface and the line.

The ASM-61 is powered by AC voltage. It is available as a standalone unit that can be mounted in a standard 19" rack using special hardware.
