UM-0840 Product Description. The UHF Low Fiplex Digital DAS has a modular structure that consists in two different modules in star configuration, the Digital Master Unit model DH4L00-M (center of the star) and Digital Remote Unit model DH4L37-R (legs of the star) that can operate in the UHF frequency range of 406-424MHz. Each one of the different modules is enclosed in the same or equivalent case, therefore, product description and installing instruction sections are valid for all of them. The Fiplex Digital Master is a RF-to-Fiber and Fiber-to-RF conversion system. These conversions are done using FPGA based Digital Signal Processing. It provides a connection to the Base Station and it centralises all the connectivity of the DAS. It also provides the possibility to connect up to six Digital Remote Units. The Digital Remote Unit, also is a RF-to-Fiber and Fiber-to-RF conversion system. These conversions are also made using FPGA based Digital Signal Processing. It provides amplification to the RF signals needed to provide signal amplification into the target area. The Master and Remote Units is where the RF interfaces are located, the Master Unit has the “To Base” RF Port, and the Remote Unit has the “To Mobile” RF Port. The advantages of using digital signal transportation over fiber are to avoid the addition of the fiber analog noise when it is used to transport analog signals. Along with this, the UL squelch of the Digital Remote Unit works not only per channel but also per time slot, this makes the Fiplex Digital DAS solution unique by its outstanding management of the UL noise. The Fiplex Digital Master Unit also provides an access point to monitor and control all the system parameters not only of the Digital Master Unit but also to each Digital Remote Unit connected on the system. This connection can be done locally via USB or Web-Browser, or remotely using Ethernet (via SNMP protocol). The DH4-L series are NFPA Ready orderable with AC or DC option. As optional it can have remote control via Ethernet or via wireless modem. The Digital Master Unit and the Digital Remote Units both have heavy duty IP67/NEMA4X cabinet for outdoor usage, it is designed to be wall or pole mounted, however, to mount on standard 19” rack, a special mounting kit can be supplied. For more details refer to the product datasheet. UM-0840 2.1 Digital Master Unit Ports If the Digital Master Unit is equipped with internal duplexers, the enclosure will only have one “To Base” RF Port. If the Digital Master is prepared for custom external duplexers, the enclosure will have two RF Ports, “Dl In” and “UL Out”. UM-0840 2.2 Digital Remote Unit Ports If the Digital Remote Unit is equipped with internal duplexers, the enclosure will only have one “To Mobile” RF Port. If the Digital Remote Unit is prepared for custom external duplexers, the enclosure will have two RF Ports, “Dl Out” and “UL In”. UM-0840 2.3 UM-0840 Connection Diagram 2.4 FO Connection 2.4.1 FO Connection in Master Unit Note: Each fiber connection is performed with simplex fiber and LC-APC connector. UM-0840 2.4.2 FO Connection in Remote Unit Note: Each fiber connection is performed with simplex fiber and LC-APC connector. UM-0840 2.5 Interface with signal source The interface with a Signal Source can be done in three different ways, depending on the availability of separated UL and DL connectors. In cases when the signal source will be picked from the air, there is no need to add a Signal Booster to feed the Digital Master. The Digital Master in its standard configuration can pick the signals from the air just by connecting a donor antenna to it. In case when a BTS is used as a Signal Source and the coupling is made thru a Point Of Interconnection (POI). A POI, can consist on a simple attenuator, duplexer, coupler or a combination of them and it is needed to accommodate the DL level to the design requested level.
