DCC Series™ – DAS Carrier Conditioner for Indoor and Outdoor Fiber DAS Systems
Combining single- or multi-band RF signals, adjusting RF power levels and providing monitor ports for fiber DAS systems, all available in one tray: Microlab’s DCC Series™ DAS Carrier Conditioners.
Both, Passive DAS systems and Fiber DAS systems are used in indoor venues and outdoor installations. DAS Systems improve coverage and optimize network capacity. If it is about combining multiple sectors of one carrier to increase capacity, or combining multiple carriers in a neutral-host system, Microlab’s DAS Carrier Conditioners are the answer. Microlab’s DCC Series™ range from simple signal combinations to sophisticated solutions with settable power levels and monitor ports. These systems are available in 19” rack mount systems for inside installations or in protected enclosures that provide IP66 / NEMA 4 protection.
DCC Signal Conditioner
Fiber DAS systems operate with certain input signal strength, usually 0dBm. Small, Macro, Micro or Pico cells deliver much higher levels. To ensure that the fiber converter input is not distorted or even damaged, incoming Tx signals have to be attenuated. Furthermore, if the DAS deployment has to handle multiple carriers, our DAS Carrier Conditioners combine incoming frequency bands and equalize different power levels.
Designed to interface four Tx/Rx signal blocks with a fiber system, the DAS Carrier Conditioners allow independent level adjustment of both, Tx and Rx signal paths. The units duplex each of the Tx/Rx inputs. Tx outputs are combined using a 4:1 Hybrid Combiner. The combined Tx signal is then attenuated by a fixed low PIM attenuator. The next step is a variable 0-30 dB attenuator for level adjustment to achieve optimum DAS performance. The DAS Rx signal is fed to a similar level adjustment stage, before being split into 6, with 4 to the Duplexers and 2 Rx to location monitoring ports. Many other variations are available.
Microlab’s DCC Series™ DAS Carrier Conditioners offer solutions for: combining various bands and equalizing dissimilar RF signal levels. Our DCC’s are available in standard configuration or tailored to any particular RF requirement.
