2. Introduction Page 14 7.Manual MF0200A0A ION-U_H_17P2_uc_19-July-13.docx User’s Manual for ION®U 2. Introduction 2.1. Purpose Mobile telephone and public safety systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area to carry voice and data traffic. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distributed antenna system (DAS). Office buildings, sports arenas, college campuses, industrial parks, and other areas of high demand require the specialized capacity boost that an optical DAS can provide to meet increasing customer demands for voice and data. An optical DAS contains optical Master Units and a sufficient number of Remote Units to provide the necessary coverage. The number of the Remote Units depends on the coverage requirements of the DAS. The Remote Units are connected to the Master Unit with optical links. The Master Unit is the connection to the Base Transceiver Stations. The configuration of a Master Unit depends on the number of the Remote Units and the frequency range. RF signals are transported to and from the remote units via optical fibers. 2.2. ION-U High Power Remote Units The ION-U is an optical fiber based DAS system that efficiently takes the outputs of multiple Base Transceiver Stations (BTS) sectors and converts those RF signals to optical to send them over fiber optic cables to remote units to provide coverage in indoor and outdoor locations. The system supports both low power and high power remotes units and SISO and MIMO operation. The ION-U H 17P2 is a multi-band, multi-operator high power remote unit optimized for CDMA2000, EV-DO, WCDMA, HSDPA, and OFDM modulation in the 1700 MHz band. It is provisioned for future modulation and frequency bands. These Remote Units feature independent downlink and uplink gain adjustments and an integrated channel power detector for in-band spectrum and PIM analysis and end-to-end auto leveling. The unit utilizes a single fiber to support multiple bands in both the uplink and downlink directions. WDM (Wave Division Multiplex) filters are integrated in the optical modules. For the UL, a wavelength within 1546 nm – 1550 nm is used. For the DL, a wavelength of 1310 ±10 nm is used. The maximum output power for the UL and DL is 6.7 mW.

Functional Description 3.1.1. eCPD+ (Enhanced Channel Power Detector plus) The enhanced Channel Power Detector plus (eCPD+) is a remote-controlled data acquisition system for monitoring the RF output power of the RU at the air interface. These measurements are monitored by the master unit. 3.1.2. Fan Protection Kit In order to protect the fan unit in outdoor use (e.g. against rain), a protective cover is delivered with the unit that can be mounted over the fan unit. For indoor applications, mounting of the fan protection kit is not mandatory. 3.1.3. Accessories A number of accessories are available for the Remote Unit such as shrouded housing, connecting boxes, and iso-trafo kits. A short version of the Remote Unit designed to be mounted in a protective shroud is also available. The shroud provides protection for the Remote Unit, an Extension Unit, and an optional cross-band coupler. The short versions of the RU and EU are required when using the shroud. figure 3-1 Shroud with RU and EU

Optical-Fiber Cable Connection Rules for Optical-Fiber Connection Optical signals are transmitted by use of optical fibers. When connecting these fibers observe the following instructions.  Note: Care should be taken when connecting and disconnecting fiber-optic cables. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fiber-optic connectors not in use. In general, optical fibres do not need special protective measures. However, protection against environmental influences e.g. rodents and humidity must be considered. The optical fibre is a single mode fiber. Type is E9/125 µm with the following minimum requirements: Attenuation: <0.36 dB / km @ 1310 nm / <0.26 dB / km @ 1550 nm Dispersion: <3.5 ps / nm km @ 1310 nm / <18.0 ps / nm km @ 1550 nm The specified bending radius of the optical fibers must not be exceeded. The pigtails for the connection between master unit and remote unit must have a sufficient length. The fibers must be protected where they enter the units. The system attenuation of the optical fibers, including the connectors, must not exceed 10 dB. System attenuation and attenuation of optical components must be determined. This can be achieved by measuring attenuation and reflection with an appropriate measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference plug) can be assumed due to the dead zone of the reflectometer. These measurements must be made with a sufficient length of optical fiber, at the input and output of the device which has to be measured. Fiber-cable connectors have to be of the same type (Radiall Opus LC-APC) as the connectors used for the unit. The fiber-optic cables are connected to the optical transceiver. Angled connectors are not compatible with straight optical connectors; non-compatibility of connectors will result in permanent damage to both connectors.
4. Commissioning Page 32 7.Manual MF0200A0A ION-U_H_17P2_uc_19-July-13.docx User’s Manual for ION®U Before connecting the fiber cables, follow the procedure below to ensure optimized performance. It is important for these procedures to be carried out with care:  Remove fiber-optic protective caps.  Do not bend the fiber-optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission.  Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fiber-optic cable that will be inserted in the optical connectors on the donor interface box.  Blow out the laser receptacle with clean and dry compressed air to remove any particulate matter.  Do not use any index-matching gels or fluids of any kind in these connectors. Gels are intended for laboratory use and attract dirt in the field.  Connect the fiber-optic cables by following the instructions in the next chapter. 4.2.11. Assembly Instructions for Optical LC Patch Cables The RU optical connector (Opus Short Plug kit) supports both simplex (one fiber cable) and duplex (two fiber cables) operation.
