Purpose Cellular telephone systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area. 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 distribution system. Such a system contains an optical Master Unit and several Remote Units. The number of the Remote Units depends on the hardware and software configuration. 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 the remote units via optical fibers. 1.5. The ION-U L 7/8/85/17/19 Remote Unit The ION-U 7/8/85/17/19 is a low power remote unit for Cell700, LMR800, Cell850, AWS, and Extended PCS1900 Band Applications. The unit is compatible with analog, GSM, EDGE, IS-95, CDMA2000, EVDO, W-CDMA, HSDPA, and LTE modulation standards. It is used in conjunction with a Master Unit in the ION optical distribution system. This system transports multiple signals simultaneously, providing a cost-

effective solution for distributing capacity from one or more base stations. The ION-U 7/8/85/17/19 transports signals on the RF layer in a very inexpensive manner. This means that multiple operators and multiple technologies are moved simultaneously from a cluster of base stations to a remote location over the same fiber. The ION optical distribution system is a cost-effective coverage solution for dense urban areas, tunnels, subway, airports, convention centers, high-rise buildings, and other locations where physical structures increase path loss. It has been specifically designed to reduce zoning problems and to provide homogeneous coverage and capacity. MF0147A0A Page 15 0 Introduction The ION-U L 7/8/85/17/19 is capable of supporting both SISO and MIMO. RF signals are transported to the remote units via single mode fiber at 1310 nm. MIMO is achieved with the use of 4 fibers and the pairing of two interlinking RUs. The system includes an Automatic Gain Control (AGC) that avoids field adjustments and reduces design, installation, and optimization time. The ION is easily set-up and supervised via a graphical user interface (GUI). Remote Units can be commissioned using built-in is compensated through the AGC. Autolevelling allows the output power to be levelled as specified in the system configuration. The entire system may be monitored remotely via an Andrew OMC. This platform uses SNMP protocol and is compliant to X.733 standard. Should a sophisticated interface not be required, the Master Unit can be directly connected to the alarm interface of a base station via a LAN (local area network) or its contact relay.

SISO and MIMO Operation The modular architecture of the ION-U 7/8/85/17/19 supports both SISO and MIMO operation. MIMO operation is achieved by pairing two RUs. The following figures show views of a single ION-U 7/8/85/17/19 remote unit for SISO applications and two ION-U 7/8/85/17/19 remote units paired for MIMO applications. figure 2-1 Remote unit, SISO figure 2-2 Remote unit, MIMO Two units paired MF0147A0A Page 17 2.2.

For mounting the cable connector, it is recommended to refer to the corresponding documentation of the connector manufacturer. The bending radius of the antenna cables must remain within the given specifications. MF0147A0A Page 31 3 Commissioning The selection of cable and antenna is an important consideration. On the one hand, a cable with higher loss is less expensive but, on the other hand, it impairs performance. Use an appropriate torque wrench for the coupling torque of N-type connectors (2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type antenna connectors. For example, use torque wrench of item no. 244379 available from the CommScope e-catalog. Do NOT use your hands or any other tool (e.g. a pair of pliers)! This might cause damage to the connector and lead to a malfunction of the Remote Unit. To minimize passive inter-modulation (PIM) distortion, attention must be paid to the physical condition of the connector junctions. Do not use connectors that show signs of corrosion on the metal surface. Prevent the ingress of water into the connector. Attach and torque the connectors properly. 1. Route the antenna cable from the antenna or splitter to the base of the RU. 2. Cut the cable to length and terminate the cable with an N-type male connector. 3.

Optical-Fiber-Cable Connection - Rules Main optical system parameters:

Fiber:

Single mode fiber, type is 9.5/125 m Fiber-cable connectors LC/APC ION-U system:

The pigtails for the connection between Master Unit and Remote Unit must have a sufficient length. Protection for the optical fibers must be provided where the fibers feed into the units. The system attenuation of the optical fibers, including the connectors, must not exceed 5 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-System Installation:

Fiber-cable connectors have to be of the same type (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. 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 just before making the fiber connections. Do not leave any LC/APC connectors open as they may attract dirt. Unused optical connectors must always be covered by their caps. Do not bend the fiber-optic cable in a tight radius (< 5 cm) as this may cause damage to the cable 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. Use a fiber end-face inspection tool to scan both, the class fiber and its surrounding area. Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches. MF0147A0A Page 35 3 Commissioning Connect the fiber-optic cables by inserting the cable end into the laser receptacle. 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. Note:

Care should be taken when connecting and disconnecting fiber-

optic cables - use the connector housing to plug or unplug a fiber. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fiber-optic connectors not in use. Cleaning Procedure for Fiber-Optical Components:

Any contamination in the fiber connection results in additional optical transmission loss which could cause whole system failure. It is thus recommended that every fiber connector be inspected and cleaned prior to mating. The goal is to eliminate any dust or contamination and to provide a clean environment for the fiber-optic connection. When you clean fiber components, always complete the following steps carefully:

1. Turn off the ION-U system (laser sources) before you inspect fiber connectors. Never look into a fiber while the system lasers are on!

2. Check the connectors or adapters with a fiberscope before cleaning. 3. If the connector is dirty, clean it with a lint-free wipe (dry cleaning). 4. Inspect the connector. 5. If the connector is still dirty, repeat the dry cleaning technique. 6. Inspect the connector. 7. If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning) followed immediately with a dry clean in order to ensure no residue is left on the endface. 8. Repeat steps 5 through 7 until endface is clean. Note: For a more detailed description, please refer to:
