MBF-20 AMERICAS REMOTE

PRODUCT DESCRIPTION AND USER’S MANUAL

1 Introduction

Axell’s MBF-20 Multi-Band Fiber Optic system provides a cost-effective, scalable indoor

solution for single or multi operator use. Signals are coupled off from a nearby base

station or off-air repeater to the OMU and then distributed via fiber to one or several

MBF-20 remote units. These MBF-20 remote units can be installed up to 2 km from the

base station site, offering great flexibility when providing RF coverage in areas where off

air transmission is not a preferable solution.

A distributed antenna system can be used to distribute the signal throughout the area to

be covered. A single F/O cable is used to connect the MBF-20 remote units to the OMU.

Different colors (wavelengths) are used in order to combine the uplink of different MBF-

20 remote units in a very cost effective way.

The MBF-20 is supplied in two physical configurations:

• Dual-band – consists of a single (Master) unit supporting two bands

• Quad-band – consists of two cascaded units: Master and Expansion (Slave) units,

where the Expansion unit can be assembled by the user onto an existing Master

MBF-20 unit (see section

3.2).

The MBF-20 is installed in conjunction with Axell Wireless Optical Management Unit

(OMU II). The OMU II provides the head-end RF to optic conversion required to

transport the services over fibre to the MBF-20 units. Up to 24 MBF-20 can be fed and

managed from a single OMU II system.

MBF-20 commissioning is designed for plug-and-play simplicity: just mount, connect

antennas, power and fibre. The unit is automatically discovered and commissioned on

the OMU II side via a Web GUI connection to the OMU II.
