3 Installation Guidelines This chapter provides installation guidelines for the Corning ONE wireless platform MRU. The following installation rules are based on the assumption that the site survey and installation planning (including power requirements) have been completed. This includes planning the distribution of antennas to provide the required coverage, as well as planning the layout of the devices and cables in the telecom closet or shaft. 3.
3.3.1.1 Rack Safety Instructions The following guidelines are relevant to the rack installed units. Review the following guidelines to help ensure your safety and protect the equipment from damage during the installation. • • • • • Only trained and qualified personnel should be allowed to install or replace this equipment. The equipment has been designed to operate at the temperature range as stated in the product specifications.
3.4.4 Cable Routing Ensure all cables, e.g. power cable, feeder cable, optic fiber, commissioning cable, connecting are properly routed and secured so that they are not damaged. 3.5 RF Coaxial Cable Guidelines 3.5.1 General RF Cable Installation Procedures Note: The installer should be familiar with the ANSI/TIA/EIS-568 Cabling Standard guidelines. • • • • Observe the general cable installation procedures that meet with the building codes in your area.
3.5.3 Coax Cable Lengths and Losses Use coax RG-223, 50 ohm, for RF connections between MRU unit and DAS antennas. Note: The required distance between the antennas (installed in the ceiling) depends on the infrastructure and calculated path-loss. For example, if there is free space-loss between the antennas, a minimum distance of 100 ft is required; if there are partitions (loss) between the antennas, a distance of less than 100 ft between them is allowed.
• Broadband frequency: 300 – 3000 MHz • -20 dB coupling (SMA coupling port) • Max. VSWR/return loss:12 dB • Max. insertion loss (dB): 0.2 • • Number of antennas that can be connected (with cables/splitters) – it is not recommended to connect more than one antenna per connector since 1:1 connectivity is reduced with each split. Types of couplers/splitters – depends on number of splits (not recommended) 3.6.
