Table 1 lists the standard RAUs that are supported in this document. Table 1.
PRODUCT OVERVIEW InterReach Spectrum supports up to 8 bands in a single system. Each antenna location supports those bands in modular, group pairings. Each location includes a Main Remote Access Unit (MRAU) that can power up to three additional Secondary RAUs (SRAUs), each of which support two power amplifier pairs for a total of eight amplifiers. MRAUs and SRAUs are grouped logically based on common service provider groupings and include: 850/1900, 700/700 MIMO, 800/900 SMR, 700 SISO/AWS, and 800/AWS.
Figure 1 illustrates how RF and IF signals are sent between Spectrum units and modules. NOTE: All FWD ports on all Modules are color‐coded red and all REV ports are color‐coded blue, which makes the DRU, IFEU, and RAU cabling process easier to complete.
Main Remote Access Units The Main Remote Access Unit (MRAU) receives FWD IF signals from an IF Expansion Unit (IFEU), which is part of the Spectrum Expansion Module Group, using 75 CATV cable. The MRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The MRAU also receives configuration information and power from and sends its status information to the IFEU. The MRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable.

Secondary Remote Access Units A Secondary Remote Access Unit (SRAU) receives FWD IF signals from the MRAU, using 75 CATV cable. The SRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The SRAU, through the MRAU, also receives configuration information and power from and sends its status information to the IFEU. The SRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable.

RAU N Connectors Each RAU also has one or two 50‐ N‐type connectors that connect to a passive antenna. Table 2 lists the number of N‐type connectors available on each RAU model. Table 2.
INSTALL THE RAUS AND ANTENNAS Follow the steps in the order provided to install the RAUs and antennas. Mount the RAUs and Antennas CAUTION! Wet conditions increase the potential for receiving an electrical shock when installing or using electrically powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm. CAUTION! This system is a RF Transmitter and continuously emits RF energy.
3 Connect a passive multi‐band antenna to the N connector on each RAU using coaxial cable with the least amount of loss possible. (See “Omni Antenna Specifications” on page 25 for information on the Omni Antenna ports.) CAUTION! Firmly hand‐tighten the N connector. DO NOT over‐tighten the connector.
6 Connect F connector CATV cables on the IFEU and MRAU, in the order given below. If the LEDs do not perform as described in this procedure, refer to “MRAU LEDs” on page 6. a Connect a CATV cable from one of the IFEU FWD Module IF OUT connectors (1 ‐ 8) to the MRAU FWD IF IN connector. b Confirm that the MRAU FWD IF IN LED is yellow, which indicates a correct physical connection.
9 Connect F connector CATV cables from the MRAU to an SRAU, in the order given below. If the LEDs do not perform as described in this procedure, refer to “SRAU LEDs” on page 8. a Connect a CATV cable from an MRAU FWD SECONDARY PORT (1, 2, or 3) F connector to the SRAU SECONDARY FWD F connector. b Confirm that the SRAU SECONDARY FWD LED is yellow, which indicates a correct physical connection.
10 Repeat Step 9 to install up to two more SRAUs, as per system design.
Propagation Delay System Delay <12 microseconds per DRU link (For example, in a cascade of 3 DRUs, the overall System Delay could be up to 36 microseconds. This does not include Fiber Delay, just System Delay along each segment of the cascade.)
