2-2The RF cable must have an SMA male connector for the connection to the Remote Transceiver. If theantenna has a different RF connector, say, N or TNC, an RF adapter must be used. Plug in the transmit(downlink) fiberoptic cable connector into the OPTICAL IN on the Remote Transceiver and the receive(uplink) fiberoptic cable connector into the OPTICAL OUT (Green) on the Remote Transceiver.From the initial network design, the output power required from each Remote Transceiver should beknown. This can be preset before power is turned on by turning the Output Power adjustments on eachRemote Transceiver. From the maximum output power rating for each Remote Transceiver, the power canbe reduced in 2 dB using the indented potentiometer.Turn the power on to the Remote Transceivers and on the Hub Shelf. Proper operation of the opticalsystem is indicated by a green Node Function LED on each of the Hub Transceiver Plug-Ins that isconnected to an active Remote Transceiver. All other alarm indicators should be OFF. A yellow LED atthe plug-in or at the Remote Transceiver indicates that the optical loss in that path is > 4 dB and is,therefore, out of the range of the guaranteed specification.Before connecting the Hub Shelf to the BTS or Repeater, check  that the RF transmit power from thesource (BTS or repeater) is within the safe operating range of the OFFICECELL and that it is at the levelrequired for proper noise and distortion performance according to the network design (see Table 1).Table 1.

The Remote Transceivers and theplug-ins have been calibrated at the factory and the optical loss compensation in each Remote PowerSupply and plug-in automatically equalizes the gain in each link so that the specified link gain is alwaysmet. The system is now operational and no further adjustment is necessary.IMPORTANT NOTE!  to comply with FCC RF Exposure compliance requirements, the followingantenna installation and device operating configurations must be satisfied:Any antenna connected to this device must result in an ERP < 1.5W(800 and  900MHz) or < 3.0W(1800MHz and 1900MHz)! and must be mounted such that there is at least 20centimeter spacingfrom the antenna structure and a human body.
