Section1 Safety & Certification Notice Confidential & Proprietary 11/115 SC‐DAS
“Only qualified personnel are allowed to handle this unit. Read and obey all the warning labels attached in this user manual” Any personnel involved in installation, operation or service of the SOLiD Technology repeaters must understand and obey the following: ‐ 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.
Section2 System Overview 2.1 General overview 2.
2.1 General overview SC‐DAS platform is a coverage system for in‐building services delivering seamless, high quality voice and data As a distributed antenna system, it provides analog and digital phone services in multiple bands through one antenna. The system covers public and private venues such as: z Shopping malls z Hotels z Campus areas z Airports z Clinics z Subways z Multi‐use stadiums, convention centers, etc.
z Support multi‐operator in a band(Max. 2 operator) Low OPEX / CAPEX Compact design Upgradable design Easy installation and maintenance Adopts auto ID scheme The SC‐DAS platform will serve two primary segments; first as a carrier deployed coverage enhancement product for their specific frequencies and second as a low cost, public safety / single carrier product.
2.2 System overview SC‐DAS comprises the components listed below. The base system consists of a BIU (BTS Interfcace Unit), an ODU (Optic distribution Unit) and a ROU (Remote Optic Unit). For use with multiple ROU’s, it has OEU (Optic Expansion Unit). The BIU has two layer which support both SISO and MIMO configuration using separate optical fiber cable. Fig2.1 shows basic system topology for SISO Figure 1.
Figure 2.2 – Basic system topology supporting MIMO configuration As shown at Fig.’s 2.1 and 2.2, one strand of fiber is needed for SISO configuration but two strands are needed for MIMO cofiguration when connected with an ROU. Applications requiring up to 32ROU’s for SISO are possible with one BIU. Each SISO ROU will require an additional strand of fiber and an additional 32 ROU’s can be added to the same system for MIMO applications. MIMO requires 2 strands of fiber per ROU as well as MIMO specific ODU’s.
To reduce number of optical cables between multi‐building applications, we can utilize the OEU(Optical Expansion Unit) Fig 2.3 shows expansion system topology supporting SISO configuration using OEUs Figure 2.3 – Expansion system topology supporting SISO configuration Figure 2.

4.2 ODU (Optic distribution Unit) ODU receives TX RF signals from upper BIU and converts them into optical signals. The optical signals are sent to ROU through optical cables. This unit converts optical signals from ROU into RF signals and sends the converted signals to BIU. For each shelf of the ODU, up to two DOUs (Donor Optic Unit) can be installed in it. One DOU is supported with four optical ports. Therefore, one ODU can be connected with eight ROUs.

4.2.6 ODU Interface with BIU SISO Configuration MIMO Configuration Figure 4.17 BIU/ODU interface For SISO configuration, up to four ODUs can be stacked. above the top of the BIU. For MIMO configuaration, up to eight ODUs can be stacked above/below the BIU. In this case, it is recommended to leave a 1RU space between BIU and the ODUs otherwise heat from BIU may degrade the performance of the ODUs, Figure 4.
As shown in the figure below, connect one coaxial cable for TX and another coaxial cable for RX with corresponding ports at the rear of BIU. For power supply and communication, connect 25Pin D‐Sub Connector cable to the corresponding port. Figure 4.
4.3 OEU (Optic Expansion Unit) OEU is mainly used to remotely deliver signals for Campus clusters. At the upper part, this unit combines with ODU and receives TX optical signals to convert them into RF signals. Then, it regenerates the signals to secure SNR and converts them into optical signals. The signals are sent to ROU through optical cables.

2) Expansion Wavelength Division Multiplexer(EWDM) EWDM module handles the optical to RF conversion of TX signals as well as the RF to optical conversion of RX signals. This multiplexer communicates with the BIU using the built in FSK modem. It also has an ATT to compensate for optical cable loss between ODUs. Finally , it has internal WDM so it needs only one optical cable to work with an ROU. Figure 4.

4.4 ROU (Remote Optic Unit) The ROU consists of two units: the MRU(Main Remote Unit) and the ARU(Add on Remote Unit). The ROU is considered the combination of MRU and ARU. The MRU receives TX optical signals from the ODU or the OEU and converts them into RF signals. The converted RF signals are amplified through a High Power Amp in a corresponding RU, combined with the Multiplexer and transmitted out the antenna port.
