2 Introduction ID No: 163511 Page 11 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 a remote unit. The number of the remote unit depends on the hardware and software configuration. The remote unit is 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 base transceiver stations. 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 MMR8L L SINGLE BAND REMOTE UNIT The MMR8L L is a single-band multi-operator remote unit. It is used in conjunction with a master unit in the MMR optical distribution system. This system transports the whole LMR band simultaneously providing a cost effective solution for distributing capacity from one or more base stations. The MMR8L L transports signals on the RF layer in a very inexpensive manner. This means that services from various operators can be transmitted simultaneously from a cluster of base station to a remote location over the same fibre.

4 Installation ID No: 163511 Page 17 4.2. ELECTRICAL INSTALLATION 4.2.1. General Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. 1. This unit contains dangerous voltages. Loss of life, severe personal injury or property damage can be the result if the instructions contained in this manual are not followed. 2. It is compulsory to ground the unit before connecting power supply. A grounding bolt is provided on the cabinet to connect the ground bonding cable. 3. 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. In areas with strong lightning it is strongly recommended to insert additional lightning protection. 4. If the mains connector of the remote unit is not easily accessible, a separation device in the mains circuit must be provided within easy reach. 5. Before connecting or disconnecting the mains connector at the remote unit, ensure that mains supply is disconnected. 6. Make sure that an appropriate circuit breaker and an overcurrent limiting device are connected between mains and remote unit. 7. A connection of mains supply to a power socket requires the power socket to be nearby the remote unit. 8. The remote unit might be supplied from IT mains. (The maximum nominal line to line voltage must not exceed 400VAC). 9. Incorrectly wired connections can destroy electrical and electronic components. 10. To avoid corrosion at the connectors caused by electrochemical processes, the material of the cable connectors must not cause a higher potential difference than 0.6V (see electrochemical contact series). 11. It is sufficient to tighten the N antenna connector hand-screwed. Any use of a tool (e.g. pair of pliers) might cause damage to the connector and thus lead to malfunctioning of the remote unit. 12. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage limiting device. 13. The unit complies with the surge requirement according to EN 61000-4-5 (fine protection); however, it is recommended to install an additional medium (via local supply connection) and/or coarse protection (external surge protection) depending on the individual application in order to avoid damage caused by overcurrent. 14. Observe the labels on the front panels before connecting or disconnecting any cables.
User’s Manual for Remote Unit MMR8L L Page 18 M0106ASB.doc 4.2.2. Connections figure 4-3 Connector flange 4.2.3. Grounding figure 4-4 Grounding bolt Grounding must be carried out.

4 Installation ID No: 163511 Page 19 4.2.4. Power Connection Before connecting electrical power to the units, the system must be grounded as described in the previous chapter. Mains power must be connected at the mains connector of the unit (see figure 4-3 Connector flange). The power supply plug is part of the delivery. The correct wiring of the power supply plug is as follows: G1055Z0 G1055Z0 figure 4-5 AC mains plug figure 4-6 DC mains plug For the AC power supply connection, a minimum cross section of 1.5 mm2 is required and for the DC power supply connection, a minimum cross section of 2.5 mm2 is required. Each wire must observe the applicable national regulations regarding loop impedance, voltage drop, and methods of installation. Make sure to connect the correct voltage to the unit. ) Note: Do not connect or disconnect the power cord at the mains connector while power is on. Turn off mains* power before connecting the power cord at the remote unit, then, engage mains again. * Mains power must be interrupted with an external mains breaker. For the mains breaker, observe the following recommendation: 120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50/60 Hz AC service is needed, i.e. the external AC breaker should be 20 Amps max. for 120-Volt service or 16 Amps for 240-Volt service. For the DC power supply, observe the local regulations of the DC service provider.
User’s Manual for Remote Unit MMR8L L Page 20 M0106ASB.doc 4.2.5. Connection of the Antenna Cables The remote unit has an N-type antenna connector or can be delivered with a 7/16 adapter. For its location please refer to figure 4-3 Connector flange. For mounting the cable connectors, it is recommended to refer to the corresponding documentation of the connector manufacturer. The bending radius of the antenna cables must remain within the given specifications. For the selection of cable and antenna it should be considered that a cable with higher loss is less expensive but on the other hand it impairs performance. It is sufficient to tighten the N-type (or 7/16) antenna connectors hand-tight. The use of a tool (like pliers) may cause damage to the connector and, therefore, lead to a malfunctioning of the remote unit. 4.2.6. Optical Fibre Cable Connection In case of a backbone structure it has to be guaranteed that there is a minimum wavelength difference of 20 nm. This will be guaranteed by using four different optical interfaces with four different wavelengths according to ITU grid. Thus, there are also four different remote units. In one optical backbone, each type of unit can only be used once! Rules for optical fibre connection Optical signals are transmitted by use of optical fibres. When connecting these fibres observe the following instructions. ) Note: Care should be taken when connecting and disconnecting fibre optic cables. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fibre optic connectors not in use. In general optical fibres do not need special protective measures. However, protection against environmental influences e.g. rodents and humidity must be considered. The optical fibre is a single mode fibre. Type is E9/125µm with the following minimum requirements. Attenuation: <0.36 dB/km @ 1310 nm / <0.26 dB/km @ 1550 nm Dispersion: <3.5 ps/nm km @ 1310 nm / <18.0 ps/nm km @ 1550 nm
4 Installation ID No: 163511 Page 21 The specified bending radius of the optical fibres must not be exceeded. The pigtails for the connection between mini master and remote unit must have a sufficient length. A protection for the feeding into units must be given. For MMR8L L the system attenuation of the optical fibres, including the connectors, must not exceed 10 dB. System attenuation and attenuation of optical components must be determined. This can be achieved by measuring attenuation and reflection with an appropriate measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference plug) can be assumed due to the dead zone of the reflectometer. These measurements must be made with a sufficient length of optical fibre, at the in- and output of the device which has to be measured. Fibre cable connectors have to be of the same type (E2000APC) as the connectors used for the unit. The fibre optic cables are connected to the optical transceiver. ) Note: Angled connectors are not compatible with straight optical connectors; non-compatibility of connectors will result in permanent damage to both connectors. Before connecting the fibre cables, follow the procedure below to ensure optimized performance. It is important that these procedures are carried out with care: ¾ Remove fibre optic protective caps. ¾ Do not bend the fibre optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission. ¾ Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fibre optic cable that will be inserted in the optical connectors on the donor interface box. ¾ Blow out the laser receptacle with clean and dry compressed air to remove any particulate matter. ¾ Connect the fibre optic cables by inserting the cable end into the laser receptacle and aligning the key (on the cable end) with the keyed slot. ¾ Do not use any index matching gels or fluids of any kind in these connectors. Gels are intended for laboratory use and attract dirt in the field.
User’s Manual for Remote Unit MMR8L L Page 22 M0106ASB.doc 4.2.6.1. Protective Plug Connection: A protective plug is provided for the connection of the fibre-optic cables. figure 4-7 Protective plug assembly ) Note: Only high-quality connectors must be used for this type of plug. Qualified brands are Diamond or Huber & Suhner.
