Section1 Safety & Certification Notice Confidential & Proprietary 5/28
“Only qualified personnel should handle the DAS equipment. Any person involved in installation or service of the DAS should understand and follow these safety guidelines.” - 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. - The power supply unit in repeaters contains dangerous voltage level, which can cause electric shock.
- This power of this system shall be supplied through wiring installed in a normal building. If powered directly from the mains distribution system, it shall be used additional protection, such as overvoltage protection device - Only 50 ohm rated antennas, cables and passive equipment shall be used with this remote. Any equipment attached to this device not meeting this standard may cause degradation and unwanted signals in the bi-directional system.
Section2 System Overview 2.1 Purpose 2.
2.1 Purpose SMDR-NH124 is a coverage system for in-building services delivering voice and data in high quality and for seamlessly. As a distributed antenna system, it provides analog and digital phone systems that are served in multiple bands through one antenna. The system covers general public institutions and private facilities. Shopping malls Hotels Campus areas Airports Clinics Subways Multi-use stadiums, convention centers, etc.
Signals with a plurality of service provider transmit simultaneously Support multi-operator in a band Low OPEX / CAPEX Compact design Upgradable design Easy installation and maintenance Web Based SNMP or GSM Modem or UDP support (Optional) 2.2 SMDR-NH124 ROU receives TX optical signals from ODU or OEU and converts them into RF signals.

3.1 General (Remote Optic Unit) The following figure shows the block diagram of SMDR-NH124 Remote Unit. Figure 3.
3.2 Component of SMDR-NH124 Remote Unit The following figure shows internal configuration of Remoe Unit with fully RF equipped. Figure 3.2 – Inside of Remote Unit Remote Unit receives TX optical signals from Head-End and converts them into RF signals. The converted RF signals are amplified through High Power Amp in a corresponding RDU, combined with Multiplexer module and then radiated to the antenna port.

3.3 Dimension Figure 3.3 – ROU Outer Look ROU is designed in a cabinet, and provides the following functions and features. Item Spec. Remark Size(mm) 482.6(19“) x 258 x560, Including Bracket Weight 35.
Section4 System Installation 4.1 ROU Installation 4.1.1 ROU Enclosure installation ROU is designed to be water- and dirt-proof. The unit has the structure of One-Body enclosure. It satisfies water-proof and quake-proof standards equivalent of NEMA4. ROU can be mounted into either of a 19” Standard Rack or on a Wall. Basically, ROU has both of a Wall Mount Bracket and a Rack Mount Bracket. Depending on the use of the Rack Mount Bracket, the bracket can be removed.
Figure 4.1 – How to install ROU Figure 4.
ROU Wall Mount Installation Turn M12 Fixing Screws by half on the wall and fully fix the screw with a Wall Mount Bracket on it. For convenience, the Wall Mount Bracket has fixing holes to let you easily mount an enclosure. Turn the M5 Wrench Bolt by half at each side of the Heatsink of the enclosure. Put the enclosure with the M5 Wrench Bolt fixed on the fixing groove and fix the M5 Wrench Bolts into the remaining fixing holes.
ROU Rack Mount Installation Like other units, ROU is designed to be inserted into a rack. The unit occupies around 13U of space except cable connection. ROU component ROU has the following components: No.
850C+700LTEC, 700LTEF+850C 700LTEF SISO RDU, 700LTEF SISO RDU Basically, the common part of ROU should have an enclosure and it is equipped with RCPU to inquire and control state of each module, R_OPTIC to make both of electronic-optical and optical-electronic conversions, RPSU to supply power for ROU and a Multi-Plexer to help share multiple TX/RX signals through one antenna. It should have Power Cable for external rectifier or to supply required power.

ROU has one optical module in it.
Optical cables should be inserted into Optic Port outside of ROU. Using an optical slack devices in ROU, you need to coil around one or two roll of cables to be connected with the optical adaptor of ROPTIC. At this time, curvature of the optical cable should be at least 10Ø to prevent insertion loss from being increased. Through GUI, check if PD value of ROPTIC is in a tolerable range (+4~-1dBm). 4.1.
4.1.5 - Coaxial cable and Antenna Connection The coaxial cables which are connected to antenna distribued network connect to antenna port of ROU. Before connection, check the VSWR value of coaxial cable whether it is within specification using SITEMASTER . - At this time, check if the Return loss have above 15Db or VSWR have below 1.5 - The part of antenna connection fasten to port not to be loosed and not to be injected the dusty and insects - 4.1.

RSS-GEN, Sec. 7.1.2 – (transmitters) Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
