Section1 Safety & Certification Notice Confidential & Proprietary 5/23
“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.
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. All components connected to this device must operate in the frequency range of this device.
UL/CUL: This equipment complies with UL and CUL 1950-1 Standard for safety for information technology equipment,including electrical business equipment FDA/CDRH: This equipment uses a Class 1 LASER according to FDA/CDRH Rules.
Section2 System Overview 2.1 Purpose 2.
2.1 Purpose Alliance 2W 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.
2.2 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) Alliance 2W L2ROU receives TX optical signals from ODU or OEU and converts them into RF signals.
2.3 Dimension Figure 3.1 – L2ROU Outer Look L2ROU is designed in a cabinet, and provides the following functions and features. Item Spec. Remark Size(mm) 482.6(19“) x 268.5 x560, Including Bracket Weight 35.
Section3 System Installation 3.1 L2ROU Installation 3.1.1 L2ROU Enclosure installation L2ROU 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. L2ROU can be mounted into either of a 19” Standard Rack or on a Wall. Basically, L2ROU 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 3.2 – How to install L2ROU Figure 3.
L2ROU 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.
L2ROU Rack Mount Installation Like other units, L2ROU is designed to be inserted into a rack. The unit occupies around 13U of space except cable connection. L2ROU component L2ROU has the following components: No.
board Basically, the common part of L2ROU 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 opticalelectronic conversions, RPSU to supply power for L2ROU 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. In addition, L2RDU can be inserted and removed to provide service for desired band (Optional). 3.1.
MC Connector Lug Naming RPSU Terminal naming Remark numbering AC DC AC DC A AC_H -48V AC-H -48V B AC_N GND AC-N IN_GND C GND DC NC FG FG Check if the connection is the same as one seen in the table above and make sure to turn the power ON. 3.1.3 Optical Cabling L2ROU makes optical-electronic conversion of TX signals from upper ODU and OEU and makes electronic- optical conversion of RX signals. L2ROU has one optical module in it.
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). 3.1.4 GND Terminal Connection L2ROU has one GND terminal port where is on bottom side, like below - Take off the GND terminal port from enclosure and connect to ground cable, then fix it the position of enclosure again - The opposite end of the ground cable should connect to the communication GND of building 3.
- The antenna connected to L2ROU is only serviced in inbuilding 3.1.6 Insertion of L2RDU L2ROU has slots to enable up to three L2RDU modules to be inserted into the unit. You can insert a L2RDU into any slot. It is not possible to provide services with a L2RDU module alone; you need to connect the module with Cavity BPF in any case.

RF Radiation Exposure This equipment complies with RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. RF exposure will be addressed at time of installation and the use of higher gain antennas may require larger separation distances. Part 27.5 Antennas must be installed in accordance with FCC 27.50.
