Product Description. The DH437-R is an FPGA based Digital Fiber Optic Remote Unit that transmit in the Downlink frequencies of 470-488MHz and receives in the Uplink frequencies 470-488MHz for United States. This Remote Unit extends the radio coverage into areas inside the Base Station range where propagation losses prevent reliable communication. The DH437-R is fed by fiber via a Digital Master, the DH400-M. The DH400-M is connected directly to the B|ase Station with no radiating elements. The Master Unit provides the wired interface to the Base Station. The DH437-R Remote Unit is the device where the service antennas are connected. Each DH437-R has dual hardware, so it works as two identical and independent Remote Units integrated into one box. Each DH437-R has two DL outputs and two UL inputs one per each internal Remote Unit. The physical connection between the Master Unit and the Remote Unit is SM Fiber Optic cord. Each Remote unit inside the DH437-R uses a separate fiber. The Master Unit receives the DL input signal from a direct connection of Base Station, after that, it is sent though a digital link to the Remote Unit. The Remote Unit the data is converted back to RF, amplified and radiated to the Service antennas. At the Uplink Input port, the Remote Unit receives the UL signal. The UL input signal comes from the Service antennas, after that, this signal is digitally converted from RF to optical signal, and sent over the fiber. This signal in the FO cord is captured by the Master Unit, re-converted from Optical to RF and sent back to the Base Station though a direct connection. The optical link allows the system to cover places which are far away from Base Station with fewer losses. This DAS System is capable of handling 24 filters in uplink and 24 filters in downlink. The center frequency of each one of the 24 filters can be tuned via a software interface. The intermediate filtering of this equipment is performed by using FPGA based Digital Signal Processing that, among many, has the following features:
- High Selectivity vs Low Delay performance selection.
- AGC per channel and per time slot.
- Squelch per channel and per time slot.
- Integrated Spectrum Analyzer. Both Master Units and Remotes has the same a heavy duty IP67/NEMA4X cabinet for outdoor usage, it is designed to be wall or pole mounted..

Figure 13; USB Port location DH437-R 19 4.2 Starting Operation BE SURE THAT TO MOBILE AND TO BASE PORTS ARE PROPERLY LOADED EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM. 1. Turn on the repeater, connect computer to repeater through USB cable, and run Fiplex Control Software. Check that all remote units are connected to the master through fiber optic checking link status. 2. Enable channel filtering if needed and setup desired channel frequencies. If Fiplex Digital Fiber DAS is used as channel selective, user has to know what frequencies are used in base station. Each channel can be enabled independently. Channels not used can be showed / hidden using the Show channels checkboxes. If remote units are on and connected through optical fiber, the corresponding uplink frequencies will be automatically set, too. DH437-R 20 Link status 3. According to DL RF input levels, program input attenuator to avoid input overflow, and output attenuator for each remote to obtain desired output level in each remote. 4. Reciprocally, set UL band gain adjusting output attenuator of master unit. It is recommended that DL gain and UL gain be equal. DH437-R 21 Set number of active channels and frequenciesSet Input attenuatorSet Output attenuator 5. Set up squelch settings. Controls are independent in UL (for each remote) and DL (master) bands. Typical values for UL are between -110dBm and -100dBm for squelch threshold. For DL, recommended value for squelch threshold is minimum level received in any active channel minus 10dB. 6. Setup desired filter bandwidth, depending on presence of adjacent channels. In principle, recommended bandwidth filter is 90KHz due to its low delay, but if adjacent signal is detected, narrow filters can be used. Fine gain can be set to equalize input signals.
