About the DXL8000
The DXL8000
Short-Haul Microwave System
(DXL8000) is a cost-effective,
high performance,
highly reliable, flexible, and compact microwave link for short haul applications.
The DXL8000
6 to 23 GHz Short Haul Radio is also a split-mount, digital, duplex microwave radio designed
for Studio to Transmitter, Transmitter to Studio and “last mile” point to point applications. The
DXL8000 delivers aggregate data rates up to
1
70 Mbps at 64QAM modulation (license
dependent).
The DXL8000 consists of the Indoor Unit (IDU) and an Outdoor Unit (ODU) as
shown below:
The DXL8000 provides high-quality digital transmission under a Single Carrier QPSK/QAM
Modulation (SCM) scheme and is available in simplex or duplex and Hot Standby (1+1), using
the Hot Standby protection switch. The DXL8000 digital microwave transceiver can support
video and data transmissions.
• The DXL8000 is a digital mode transceiver that accepts multiple transport data streams
or an external 70 MHz digitally modulated IF signal. The input data streams are
multiplexed and are modulated onto the IF signal using Single Carrier QPSK/QAM
Modulation. Then the modulated IF signal (or external IF signal) is up-converted to the
final radio frequency (RF) required and is transmitted through the antenna.
• The DXL8000 transceiver also receives RF signals from the antenna and down-converts
the RF signals to a 70 MHz IF. The original data streams are demodulated using Single
Carrier QPSK/QAM Demodulation. IF output is also available for connection to an
external demodulator or test equipment.
The DXL8000 supports from
1
– 4 independent, user selectable transport streams, and includes
Web browser management Interface to optimize transmission parameters for maximum spectral
efficiency. Transport stream options include ASI, SMPTE 3
1
0M, in support of ATSC, DVB-T,
ISDB-T BTS and DS3 / E3,
1
00BaseTX Ethernet, RS232, RS485 and T

. The advanced
digital modulator includes Viterbi error correction for ultra-robust performance under adverse
path conditions, while the adaptive equalizer at the receiver automatically compensates for
multipath errors.
