1.2. HEALTH AND SAFETY WARNINGS

1. Only suitably qualified personnel is allowed to work on this unit and only after
becoming familiar with all safety notices, installation, operation and maintenance
procedures contained in this manual.

2. Read and obey all the warning labels attached to the unit. Make sure that the
warning labels are kept in a legible condition and replace any missing or
damaged labels.

3. Obey all general and regional installation and safety regulations relating to work
on high voltage installations, as well as regulations covering correct use of tools
and personal protective equipment.

4. Keep operating instructions within easy reach and make them available to all
users.

5. It is the responsibility of the network provider to implement prevention measures
to avoid health hazards which may be associated to radiation from the antenna(s)
connected to the unit.

6. Make sure, access is restricted to qualified personnel.

7. Use this equipment only for the purpose specified by the manufacturer. Do not
carry out any modifications or fit any spare parts which are not sold or
recommended by the manufacturer. This could cause fires, electric shock or other
injuries.

8. Due to power dissipation, the remote unit may reach a very high temperature.

9. Before opening the unit or (dis-)connecting the mains connector at the remote
unit, ensure that mains supply is disconnected.

10. ESD precautions must be observed! Before commencing maintenance work, use
the available grounding system to connect ESD protection measures.

11. This unit complies with European standard EN60950.

12. Make sure the system settings are according to the intended use (see also
product information of manufacturer) and regulatory requirements are met.

13. Although the remote unit is internally protected against overvoltage, it is strongly
recommended to earth the antenna cables close to the remote unit’s antenna
connectors for protection against atmospheric discharge.

14. Laser radiation – Class 1! Do not stare into the beam, do not view it directly or
with optical instruments.

2 Introduction

2. INTRODUCTION

2.1. PURPOSE

Cellular telephone systems transmit signals in two directions between base
transceiver station (BTS) and mobile stations (MS) within the signal coverage area.

If weak signal transmissions occur within the coverage area because of indoor
applications, topological conditions or distance from the transmitter, extension of the
transmission range can be achieved by means of an optical distribution system.

Such a system contains an optical master unit and several remote units. The number
of the remote units depends on the hardware and software configuration. The remote
units are connected to the master unit with optical links. The optical loss must be less
than 10 dB inclusive optical couplers or splitters.

The master unit is the connection to the BTS. The configuration of a master unit
depends on the number of the remote units and the frequency range.

The optical transmission uses WDM-systems with a wavelength of 1550 nm in the
uplink and 1310 nm in the downlink.

2.2. THE MMR8/19

The fibre optic distribution system is designed for AMPS/PCS or iDEN/PCS services.
Up to two bands can be transmitted. In future applications each fibre will be able to
serve up to four remote units and to operate up to four providers. One master unit
can operate up to 124 remote units.

An auto-levelling function for compensating different fibre losses and a
comprehensive supervision concept are implemented.

The remote unit MMR8/19 is connected to a central master unit through optical fibre
lines. Specific customer designs for lamp pole or wall mounting are available. Thus,
the system provides many advantages in view of easy site acquisition.
