User Manual | CMA-438-AEN | Page 10 of 44System Architecture | Figure 1-21.3 System ArchitectureFigure 1-2 illustrates the MRU system architecture. In the downlink, at the headend, BTS/BDA RF signals are conditioned by service-specific RIMs installed in the headend unit (i.e. HEU/IHU), ensuring a constant RF level. The conditioned signals are then forwarded to the OIU and converted by the OIMs to an optical signal for transporting over single-mode fiber to the MRUs at the remote locations. All mobile services are combined and distributed through a single antenna port over the broadband antenna infrastructure installed at the remote locations. In the uplink, the process is reversed. As illustrated in the system architecture shown in Figure 1-2, all mobile services are combined and distributed through a single antenna port over the broadband antenna infrastructure installed at the remote locations.

The length of cable from the risers to each antenna must be concealed above the ceiling. • The cable must be properly supported and maintained straight using Velcro® cable ties, cable trays, and clamps or hangers every 10 ft (where practical above ceiling level). Where this is not practical, the following should be observed: • The minimum bending radius of the supplied 1/2-in coax cable should be 7 in. • Cable that is kinked or has a bending radius smaller than 7 in must be replaced. • Cable runs that span less than two floors should be secured to suitably located mechanical structures. • The cables should be supported only from the building structure.• All cables shall be weather-resistant type. • Cable length is determined by the system installation plan. When calculating the cable length, take into account excess cable slack so as not to limit the insertion paths.3.5.2 RF Rules • Use coax RG-223, 50 Ohm, male-to-male QMA to N-type for RF connections from the RIMs to the BTS and 4.3-10 type for MRU.• When using the Corning remote unit in an environment in which other indoor coverage systems are installed, it is recommended (where possible) that the antennas are placed at least 2 m apart.• When bending coax cables, verify that the bending radius does not exceed the coax specifications.• Use wideband antennas supporting a range of 300 MHz to 3 GHz.• Terminate all unused MRU RF ports with a 50 Ohm load.• Make sure that the VSWR measured at the coax cable meets the product specification. The VSWR must be measured before terminating the MRU RF ports in the remote communication rooms.3.5.3 Coax Cable Lengths and LossesUse coax RG-223, 50 Ohm, for RF connections between MRU 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.• Observe the general cable installation procedures that meet with the building codes in your area. The building code requires that all cabling be installed above ceiling level (where applicable). The length of cable from the risers to each antenna must be concealed above the ceiling.

Consult the cable specification sheet for the cable you are installing. • Do not bend cable more sharply than the minimum recommended bend radius. • Do not apply more pulling force to the cable than specified. • Do not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission characteristics of the cable. The cable may have to be replaced.• Use an optical power meter and light source for checking the fiber optic cables.• Make sure the environment is clean while connecting/ splicing fiber optic cables.• All fiber optic connectors should be cleaned prior to connecting to the system.
User Manual | CMA-438-AEN | Page 19 of 44• Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are terminated.• Pay special attention while connecting the LC APC connectors – ensure that you hear a “click,” indicating a secure connection.• Never look directly into the end of a fiber that may be carrying laser light. Laser light can be invisible and can damage your eyes.3.8 Grounding Requirement Verify that the equipment has been well grounded (refer to the grounding lug on the bottom front panel of the MRU chassis).
