UNItivity – Installation Manual January 2016 4.7.3.1 Installing a Module (general instructions) In order to make a good signal connection, all modules are a very snug fit when you install them into a UNIhub. If necessary, remove any blanking panels from slots that you want to populate. To do this, remove the retaining screw using a cross-headed screwdriver. Carefully align and slide the module into the UNIhub.
UNItivity – Installation Manual January 2016 4.8 Installing the SH Essentially, this is very similar to installing a PH. The only differences are in the modules you install: Install the SH into the 19" rack. Provide mains power and switch on. Ethernet connection to SH (optional). Rear panel: Install OM. Front panel: Install any OM to be connected to RU. 4.9 Installing the RU’s RF Signal from UNIhub supplied via fiber.
UNItivity – Installation Manual January 2016 When choosing a mounting location for RU, note the following: The bracket can be mounted with the open slot at the top or side depending upon access requirements Allow for a minimum clearance of 180mm beyond the wall bracket’s open edge to allow for the RU to be slotted in once the bracket is in place Ensure that adequate space is provided to allow for any power and signal cables to be connected and that minimum bend radii of cables are me
UNItivity – Installation Manual January 2016 Both variants detailed here are provided with a pre-terminated EIAJ5 connector which plugs into the RU as shown. Local mains, via power block The power block is designed for connection to a local mains supply. It is also supplied with a 2m long mains cable with appropriate plug which terminates in a figure of 8 connector. This allows for greater flexibility when locating the RU in relation to the mains supply.
UNItivity – Installation Manual January 2016 4.9.2.1 RU 48V, via Rack-mounted Central PSU Using this connection method, you can power up to eight RU’s from a centralised location. You will need: One Rack-mount Central PSU For each RU, you will require: 1 x CAT-5 cable to connect from Central PSU to RU (RJ-45 interface) (not supplied) Proceed as follows: Install the Rack-mount Central PSU into the rack. Make up a CAT-5 power cable long enough to reach the RU.
UNItivity – Installation Manual January 2016 The wiring to the RU power supply uses two independent 48V supplies (48V1 and 48V2). Each supply has a positive and negative line connection, and each connection is made through one pair of pins of the Ethernet connector. 48V 1(A) (positive) pins 1,2 48V 1(B) (negative) pins 3,6 48V 2(A) (positive) pins 7,8 48V 2(B) (negative) pins 4,5 Note that the positive and negative polarity of 48V1 and 48V2 is not important and can be independently reversed.
UNItivity – Installation Manual January 2016 5 Fiber Optic Requirements Each fiber connection between UNIhub and RU must meet the following minimum standards and performance criteria Optical Loss: Return loss for ALL connections: Recommended Fiber: Recommended Connector Type: Less than 5dBo better than 30dB Single Mode APC IMPORTANT: To achieve best performance, the system needs 30dB back reflection to be working properly, and this has to be guaranteed throughout the entire link, so if there’s e
UNItivity – Installation Manual January 2016 5.1 Fiber Optic Interface UNItivity platform uses SC connectors on both the optical module in the UNIhub and RU. The system uses a laser in the transmit direction and photodiode in the receive direction hence the connectors are SC APC in the transmit direction (laser) and SC PC in receive.

UNItivity – Installation Manual January 2016 5.1.2.
UNItivity – Installation Manual January 2016 5.2 Use of Single Mode or Multimode Fiber cable Optical fiber cable is generally available in two types: single mode and multimode. Single mode optical fiber cables, due to the very small core size (9 µm) transmit a single ray of light whilst multimode optical fiber cable, with a larger core size ( 62.5 µm or 50 µm), carries multiple light rays with different reflection angles within the fiber core . .
UNItivity – Installation Manual January 2016 5.3 Fiber optic Connectors A fiber optic connector consists of two key elements. Connector body Type Ferrule Type There are a wide variety of connector body types used in infrastructure cabling some of the most common types are shown below. There are two main groupings standard and Small Form factor. The small form factor connectors have a 1.25mm ferule compared to the ferule size in “standard connectors of 2.5mm.
UNItivity – Installation Manual January 2016 5.4 Ferrule Types As shown above some of these connectors can be designated either APC or PC, this refers to the Ferrule within the connector body. The TIA 568 colour code for connector bodies and/or boots is: Green Blue Beige Single mode APC (angled) connectors Single mode (UPC) multimode Attaching a connector to an optical fiber cable will cause some of the light traversing that optical fiber to be lost.
UNItivity – Installation Manual January 2016 5.4.2 UPC (Ultra-polished Physical Contact) Typical Back Reflection: <-35dB for single mode fiber UPC connectors are very similar to PC connectors in that the ferrules faces are flats but have a much better return loss, which can be better than 50 dB. This performance is due to an improved polishing technique applied to the face and to the curvature at the ferrule end.
UNItivity – Installation Manual January 2016 5.4.4.1 How to diagnose an optical link with an OTDR The best way to check the return loss of a fiber link is to use an Optical Time Domain Reflectometer with the appropriate connectors and launch cables. A typical graph result is shown below: The graph shows the performance of fiber along its length. In this case the first horizontal line represents the first 250m of fiber in the launch box.
UNItivity – Installation Manual January 2016 5.4.5 Fiber Inspection and Cleaning 5.4.5.1 Inspection The optical fiber connection has two basic performance indicators: Insertion Loss and Return Loss.
UNItivity – Installation Manual January 2016 5.4.5.2 Cleaning Fibers Clean fibers are important in all installations but in multimode installations this is even more important. Ideally all fibers should be visually inspected as this gives a very clear indication of dirt on fibers. There are many optical inspection tools such as the one shown below: With the inspection tool shown above which connects to a PC the image of the fiber can be captured and examined prior to cleaning.
UNItivity – Installation Manual January 2016 6 Making the signal connections Observe safety precautions when working with fiber cables and devices (see Optical Safety Precautions on page 6). Both transmit and receive are SC Connectors. All optical devices require a Zinwave patch cord irrespective of the existing or installed fiber and connector type. Connecting Fiber Cables UNItivity platform uses fiber optic cables to connect UNIhub (OM) and RU.
UNItivity – Installation Manual January 2016 6.1 Connecting UNIhub to the fiber infrastructure Follow these instructions for each Optical Module in the UNIhub OM’s use Single Mode on Transmit (APC) and Multimode on the receive direction (PC). Both transmit and receive ports are SC Connectors All OM’s and RU’s require a Zinwave patch cord irrespective of the existing or installed fiber and connector type. Remove the protectors from the SC connectors on the OM and the Zinwave patch cord.
UNItivity – Installation Manual January 2016 6.1.1 Connecting UNIhub to an RU OM’s use Single Mode on Transmit (APC) and Multimode on the receive direction (PC). Both transmit and receive are SC Connectors. All optical devices require a Zinwave patch cord irrespective of the existing or installed fiber and connector type. V1.1 Install fiber-optic cable of sufficient length to reach the RU.
UNItivity – Installation Manual January 2016 6.1.2 Connecting an RU to Antennas The RU has separate connectors for transmit and receive antennas. As stated previously, the choice of antenna will depend upon the RF coverage and planned design for a building. This may involve using extension cables where antennas are distant from the RU. When connecting cables to the RU careful attention should be paid to the mechanical stress placed on the connector from using large inflexible cable.
UNItivity – Installation Manual January 2016 6.2 Connecting SM Inputs You can connect SM inputs (e.g. BDA, BTS, WLAN access point) only to the PH: When connecting cables to the SM, careful attention should be paid to the mechanical stress placed on the connector from using large inflexible cable. Short flexible jumpers should be used where appropriate. Make N-type male connections to the N-type female connectors on the SM (on the rear of the PH). V1.
UNItivity – Installation Manual January 2016 7 Antennas UNItivity can use a variety of antennas connected to the RU via coaxial cable. The choice of Antenna will depend on the service requirement within the operational bandwidth of the system. 7.1 Installation of two antennas As mentioned above, a pair of off-the-shelf antennas can be used to provide separated transmit (TX) and receive (RX).
UNItivity – Installation Manual January 2016 It can be seen that the isolation improves with frequency due to the increasing propagation loss, so that the PCS and AWS bands have isolation in excess of 45dB when the CELL band is below 40dB. Although this distance provides a rule of thumb for initial planning, the particular antennas in use and the environment in which they are installed will affect the isolation.
UNItivity – Installation Manual January 2016 7.1.2 Uplink/Downlink Balance Care should be taken not to separate the two antennas by so much distance that the path difference between TX and RX to the mobile affects system performance. Some services are more affected by uplink/downlink path difference than others, especially those using high dynamic range mobile powercontrol such as WCDMA. There are two WCDMA system effects to be aware of when testing a separated antenna coverage area: 1.
UNItivity – Installation Manual January 2016 7.1.3 Isolation Measurement Techniques The most accurate way of measuring the antenna isolation, is to disconnect the cables at the RU antenna ports and connect these directly to either a network analyser or a spectrum analyser with a tracking generator. Every antenna in the installation should meet the requirements of the TX-RX Isolation section above.
UNItivity – Installation Manual January 2016 8 UNItivity platform support for MIMO services The next generation of high data-rate services such as WiMAX and LTE provide various MIMO options. Where base stations (BTS) are deployed to provide in-building coverage, these options can be used to increase the overall capacity or coverage of the system.
UNItivity – Installation Manual January 2016 The following considerations should be taken into account when implementing a MIMO architecture with the UNItivity platform: • The separation between the dual-port antennas at the same location needs to be sufficient to provide both MIMO diversity (using guidelines provided by the BTS manufacturer) and TX-RX isolation.
