4-Wire Symmetrical VDSL Modem

RAD’s ASM-60 4-wire symmetrical VDSL modem provides full duplex transmission of 10 Mbps Ethernet traffic over four-wire copper cable for distances of up to two kilometers (1.2 miles). The extended distance provided eliminates the need for fiber in the Local Loop or in the campus environment. The ASM-60 4-wire symmetrical VDSL modem employs VDSL QAM line coding, thereby utilizing the bandwidth effectively. The unit is fully interoperable with third-party equipment. No configuration is needed when installing. Two versions are available: one that sits at the central office and a second version that sits at the customer site.

• Employs VDSL QAM coding for better bandwidth utilization

• Eliminates need for fiber optic interface

• Plug and play operation; no configuration is needed when installing

 

Using symmetrical VDSL technology, ASM-60 operates at rates up to 10 Mbps over 4-wire lines. The ASM-60 extends the range of digital equipment up to 2 km (1.2 miles) over 24 AWG (0.5 mm) 4-wire copper cable. This eliminates the need for optical cable in the Last Mile (Local Loop) or in the campus network environment.

 

The ASM-60 compensates for line impairments and mixed cabling by using advanced equalization, adaptive filtering, echo cancellation technology and QAM line coding.

 

Setup, control and monitoring of status and diagnostic information can be performed using an ASCII terminal connected to the async control port.

 

The ASM-60 is available as a standalone unit which can be mounted in a standard 19" rack using special hardware. Two ASM-60 units can be mounted side-by-side.
