INOVA DAS Operating Manual

This equipment’s simple information are :

- Gain : 53dB@ROU2W, 57dB@ROU5W

- Bandwidth : 28MHz@700M, 32MHz@850M, 65MHz@1.9G, 70MHz@2.1G, 10MHz@2.3G, 195M@2.5G, 70MHz@2.6G

- Output Power : 33dB@ROU2W, 37dB@ROU5W

- Input / Output impedances : 50 ohm

The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.

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.

Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut

fonctionneravec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada.

Dans le but de réduire les risques de brouillage radioélectrique à l’intention desautres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotroperayonnée quivalente (p.i.r.e.) ne dépassepas l’intensité nécessaire à l’établissement d’une communication satisfaisante.

2.2 System Network Configuration

INOVA DAS basic network configuration and optical extend configuration is as below picture.

Figure 1. Basic Network Configuration.

The MHU is connected to the base station with RF cable, and the lower ROU equipment is connected

with optic cable. Each branch of the MHU can be operated by cascade connection with each 8 ROUs,

and 1 MHU can connect up to 48 ROUs.

For service extension, extended ROU is connected by optic cable with Single ROU(Main), one branch

can operate up to 8 ROUs, so up to 4 stages of cascade is available for extend configuration.

- 700MHz, 850MHz, 1.9GHz, 2.1GHz, 2.3GHz, 2.5GHz or 2.6GHz service support.

- extension function support for all frequencies through additional MDTU and MBIU.

- 10MHz clock supply function. (Basic: external 10MHz, option: internal 10MHz)

- 2.5GHz TDD synchronization signal supply function. (Basic: external TDD Sync, option: internal TDD

Sync)

- 1Gbps Ethernet port implementation for various use.

MHU basically has single as main. When only single service is needed, one MDTU of MDRU is attached

for single service, and only one set of MBIU is configured for service. On the other hand, when extended

is configured, 2 MDTUs of MDRU are attached and 2 sets of MBIUs are configured.

3.1.1 MWDM (MHU Wavelength Division Module) Figure and Configuration

MWDM is a module for sectorization function, and can be configured up to 6 WDMs. Each optic

branch is configured with an optic connecter that is connected with alpha-sector MHU, an optic

connecter that is connected with beta-sector MHU, and an optic connecter that can transmit to lower

ROU with 4 optic signals.

3.1.3 MDRU (MHU Digital Reference Unit) Figure and Configuration

MDRU is configured with MCPU, OCXO modules. MDTU slot is configured with a total of 2, basically

uses the one slot on top, and both MDTU slots are inserted when ROU is extended. OCXO module

autonomously supplies 10MHz reference signals, and when 10MHz reference signal is supplied

externally OCXO module may not be configured. MCPU is a module for status monitoring and control

of MHU and ROU, service status can be controlled through GIU.
