MA 1500 provides a cost effective solution for extending 450 MHz signal from a single BTS
location to remote locations, up to 20 Km away, over SM F/O connections.
Simplex RF inputs and outputs support a wide variety of channel assignments, while maintaining
the service integrity via highly linear amplifiers. Intuitive GUI software enables end-to-end setup
and adjustment of the coverage to minimize interaction with outdoor signals.
The system can support two independent links, where each link can support:
• A different service
• A sector – where two links are required for two sectors of the same service
The MA-1500 system is based on the following elements:
• 1500-UHF-BU – A 1500-UHF-BU unit is installed, adjacent to the BTS location. It
performs the RF to optic signal conversion at the BTS side and transmits the services to
the remote location(s) where 1500-UHF-RU units are installed.
• 1500-UHF-RU – A 1500-UHF-RU is installed at each remote location. This unit
reconverts the signals received over the optic fiber to RF and distributes the services to
the connected antennas.
• MA-1500 GUI Tool – Intuitive GUI used for setting up, adjusting and monitoring the
MA 1500 system. (The MA-1500 GUI is the same GUI tool as for the MA-330 – described
in Chapter 4
Introduction to the MA 1500 System
MA 1500 Installation and Configuration Guide 2
1.1 System Architecture
At the Main building, the 1500-UHF-BU interfaces to the BTS via passive interface. It converts
the RF signal received from the BTS to an optic signal and transmits it over SM optic fiber to the
MA 1500 Remote. At the Remote buildings, the 1500-UHF-RU reconverts the received RF signal
to an optic signal and routes the RF signals to the antennas.
The MA-1500 system provides flexible solutions for two types of antennas – simplex and duplex.
Both solutions are illustrated in Figure
1-1.
• Simplex antennas – these type of antennas are connected directly to the remote unit: one
for the Rx and one for the Tx signal.
• Duplex – these antennas are connected to the remote unit via a duplexer. One antenna
both receives and transmits signals. Up to four duplex antennas can be connected to each
remote unit.

MA 1500 Installation and Configuration Guide 3
1.2 System Operation and Capabilities
1.2.1 Commissioning
The MA-1500 system can be configured and adjusted according to the specific installation. The
procedure is performed through intuitive GUI run via a local connection to either the 1500-UHF-
BU or to the corresponding 1500-UHF-RU unit (
Chapter
4 Setup and Adjustment Procedure
).
NOTE: The setup and adjustment procedures are end-to-end, meaning that both 1500-UHF-BU
and the 1500-UHF-RU on the corresponding link can be adjusted by connecting to either units.
1.2.2 Fault Detection and Alarm Reporting
The MA 1500 units provides the following types of fault detection:
• Front Panel LED
• Dry-contact auxiliary - 1500-UHF-BU only. Two normally closed connections used for
reporting to an external alarm system when the optic signal level is not within the required
range.
• GUI monitoring on each link, through a local connection to either the 1500-UHF-BU or 1500-
UHF-RU unit of the corresponding link
1.2.3 RF Signal Connections
1500-UHF-BU - The RF signal connections between the 1500-UHF-BU and the BTS interface
(RIU or passive interface) are supported through N-type female connectors mounted on the
1500-UHF-BU rear panel: one connector for each forward path coax cable and one for each
reverse path coax cable (two connectors for one link, four connectors for two links).
1500-UHF-RU - The RF signal connections between the 1500-UHF-RU and the antennas are
supported through four pairs of N-type female connectors mounted on the 1500-UHF-BU-2 rear
panel. One connector is used for connecting the forward path coaxial cable and one connector
for connecting the reverse path coaxial cable.
1.2.4 Optical Signal Connections
• 1500-UHF-BU - one or two optical connections, SC/APC, on the front panel, corresponding
to the number of links supported by the MA 1500 model
• 1500-UHF-RU – single optical link, SC/APC, on the front panel
Introduction to the MA 1500 System
MA 1500 Installation and Configuration Guide 4
1.2.5 Optical Signal Level Adjustment
The 1500-UHF-BU and Remote units are equipped with digital attenuators for adjusting the
forward and reverse optic signal level. The attenuators are adjusted through the GUI.
1.2.6 Powering
The MA 1500-UHF-BU and 1500-UHF-RU is powered by a 20 to 48 VDC power which is supplied
through a standard power connection to the rear panel.
1.2.7 Mounting
The MA 1500 units are specifically designed for 19” rack-mount installations. When installed, the
front panels of the units are flush with the front of the rack.
