Page 8: General Information
RA-5300 consists of Master Unit (MU) RA-0100-D, Remote Unit (RU) RA-5300-R and Combiner Unit. The low signal transmission loss of optical fiber is applicable for long distance transmission. RA-5300 can support the optical transmission of up to 6.5dB signal transmission loss. There is no isolation problem between TX and RX antennas, which means customer can select the antenna flexibly according to the real situation, such as directional or omni-directional antenna. - Page 9 USER MANUAL FOR RA-5300 POWER EXT_ALM RS-232 OP/UL DL POWER RS-232 EXT_ALM Figure 2: Front, Side and Bottom Views of RU Enclosure RA-5300 QI Copyright - refer to title page Page 9 ENU Status : 1-2-0...
