2. INTRODUCTION 2.1. 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.
provide homogeneous coverage. The compact, mechanical design is specifically architected to mount inside of or on poles and along side structures in such a way that it has a minimal visual impact. It has been specifically tested and optimized for CDMA2000, EV-DO, WCDMA and LTE. Furthermore it is provisioned for future improvements to the modulation and frequency bands. The ION-M19P/19P/19P can be easily set-up and supervised via a graphical user interface (GUI).

3.3. OPTICAL-FIBRE-CABLE CONNECTION - RULES Optical signals are transmitted by use of optical fibres. When connecting these fibres observe the following instructions. Note: Care should be taken when connecting and disconnecting fibreoptic cables. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fibre-optic connectors not in use. In general, optical fibres do not need special protective measures.
Remove fibre-optic protective caps. Do not bend the fibre-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 fibre-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.
For plug assembly, observe the following instruction: 1. Pass one or two contacts through the backshell and the clamp ring. 2. Place the contact(s) on the lower insulation body by pushing the groove of the contact into the cavity. If there is only one contact, cavity A must be used. * 3. Then, mount the upper insulation body on the lower insulation body. ** Upper insulation body Cavity B Cavity A 4. Bring the insulator into the plug.
7. Bring the plastic ring over the cable(s), push it into the backshell and compress the seals and plastic ring by screwing the clamp ring tight (no gap) using a spanner with opening 20. *** Screw tight until gap is closed 8. Connect the plug to the optical-fibre 9. To lock the connector, push the black connector of the remote unit, again by locking ring forward.**** fitting a stamp on the plug into the groove of the connector.
