1 Introduction The MRU is a mid-power (2 W) remote solution for the Corning ONE™ Wireless Platform system. The MRU provides remote indoor and outdoor coverage. It is a fiber-fed, compact and scalable multi-service solution designed to complement the Corning ONE Wireless platform by providing complete RF open space coverage for large-scale public venues such as campus applications.
1.2 General System Specifications and Requirements 1.2.1 Environmental and Regulatory Specifications Operating Temperature Storage -40° C to +65° C (-40°F to 149°F) -30° to 85°C (-22° to 185°F) Table 1-1. Temperature and Humidity Specifications 1.2.2 Safety and Regulatory Approvals Regulation/Standard Category Approval Laser Safety FDA/CE 21 CFR 1040.10 and 1040.11 except for deviations pursuant to laser notice no.
1.3 System Architecture Figure 1-2 illustrates the MRU system architecture. In the downlink, at the headend, the BTS/BDA signal is conditioned at the headend unit (e.g. integrated headend unit IHU)), by the service specific radio interface modules (RIM), ensuring a constant RF level. The conditioned signals are then converted by the optical interface modules (OIM) to an optical signal for transporting over single-mode fiber to the MRU at the remote location. In the uplink, the process is reversed.
1.4 System Monitoring and Management The MRU is centrally managed via the headend control module SW management application (v1.6 and higher). Figure 1-3 shows the management tabs of the selected MRU unit. Refer to the HCM and Web Management User Manual (v1.6 and higher) for information on how to configure and manage the MRU remote unit. Figure 1-3.
2 MRU Interfaces This chapter provides detailed descriptions of the MRU chassis and main modules and interfaces. This includes port and LED interface descriptions. The MRU comprises the following main modules: • • • • Power amplifier modules (PAM) – internal service specific power amplifier module that interfaces to an optical interface module (OIM) at the headend site via an SMF pair and supports one service. MRU supports up to five SISO bands.
The MRU front panel includes the RF and F/O interfaces in addition to the system level status LEDs and service maintenance ports. The internal PAM modules each include a PWR/STS LED. Figure 2-2. MRU External Interfaces Table 2-1 and Table 2-2 provide a description of the MRU interface ports and LED status indicators.
