2. Product Description.
The Fiplex PS800 Digital DAS has a modular structure that consists on two different modules, the Digital Master
Unit DHS00-M and the Digital Remote Unit DHS37-R. 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 Ma
ster and Remote Units is where the RF interfaces are located, the Master Unit has the “To Base” interface,
and the Remote Unit has the “To Mobile” interface. The Master and Remote Units have internal duplexers
therefore, the RF interface will have one RF p
ort in each unit, the Master will have a “To Base” RF Port, and the
Remote Units will have “To Mobile” RF Ports.
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 can be fed with a number of Base Stations or Off the Air. The direct connection to
a base station is done though the Point Of Interconnection (POI) and depending on the configuration and amount
of Base Stations it can be something simple as a directional coupler and a duplexer or something more complex
that can consist on several directional couplers, splitters, duplexers.
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 DHS00-M and DHS37-R 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.
