Comflex NG User manual 1. System Introduction 1.1 Introduction Comba Analog DAS Solution is an industrial-leading in-building distributed antenna solution for enterprise and consumer application, supporting the wide application range of cellular generations: 4G and 5G. This solution is based on analog DAS technology with wide-band and multi-band distribution architecture, flexible off-air or wired connection mode, enabling efficient utilization of signal links. It is designed to support multi-band, multi-technology, and multi-operator networks with flexible configuration and easy commissioning. 1.2 System Architecture MU – Master Unit Select dedicated radio signal, transmit to fiber signal and then transfer to fiber Hub. It can support two kinds connectivity to radio signal: off-air connection and wired connection with different module. Fiber Hub The Fiber Hub is the central Hub and Distribution element for the analog DAS system. The fiber hub interfaces between the MU and the active antenna unit, allowing it to receive the operators service signals in optical link, and to route signals to the active antenna unit. Active Antenna Unit The active antenna unit is a low-power remote antenna unit with 19~22 dBm per MIMO stream per band 1.3 System Function 1.3.1 System features 1) Supports up to 6T6R, 4G and 5G signals 2) Output power 2.5GHz/3.5GHz: 22dBm 700MHz/850MHz/1900MHz/EAWS: 19dBm 3) Network topology ⚫ MU + Fiber HUB + ARU: 1+16+256 ⚫ MU can connect to ONE slave MU ⚫ MU can extend up to 16pcs fiber Hub ⚫ Fiber HUB can connect to 16pcs ARU ⚫ MU-HUB max fiber loss 8dBo； ⚫ HUB-ARU max fiber loss distance 45dB 4) Power Supply MU & HUB: AC 110V ARU: DC 48V 5) Couple way Off-air couple : MU - BDA Card Wired couple: MU - POI card 1.3.2 Monitoring 1) Local monitor: local debug and commission 2) Remote control: Control the system in MU site 3) System upgrade：Software upgrade in MU 4) 4G/5G demodulation: Demodulate the cellular features: RSRP, SINR, PLMN 1.4 Specification 1.4.1 Optical Specification Optical Specification Operation Frequency 600MHz-1GHz,1.7GHz-2.2GHz, 3.3GHz-4GHz Fiber Mode / Simplex Wavelength nm 1310, 1550 + WDM Optical Output MU dBm -2 – +2 HUB 6-8 Return loss dB > 45 Connector Type / SC/APC 1.4.2 Cable Specification Cable Specification Operation Frequency DC-4GHZ impedance Ω 50 VSWR / ≤1.2 Insert Loss dB ≤（L*0.48+0.2）dB@DC-4GHz @ meter 1.4.3 Radio Specification Radio Specification 700MHz 850MHz 1900MHz EAWS 2.5G band C band Frequency UL MHz 698-716 / 777-787 824-849 1850 – 1915 1710 – 1755 2496-2690 3700-3980 DL 728-746 / 746-756 869-894 1930 – 1995 2110 – 2180 IBW MHz 18/10 25 65 45/70 194 280 Carrier number (off- air card) 1 1 Carrier IBW(off-air card） MHz 194 200 Uplink Output Power (PRRU) dBm +10——+20dBm input POI card:-40 +20——+37dBm input POI card: -50 Uplink Output Power (BDA Card) dBm 19 19 19 19 22 / Downlink max output power (ARU) dBm 19 19 19 19 22 22 Downlink input range (BDA Card) dBm -95 —— -50(RSRP) -100—— -55(RSRP) Downlink input range (PRRU Card) / +10——+20dBm(RSSI) input +20——+37dBm(RSSI) input +10——+20dBm(RSSI) input +20——+37dBm(RSSI) input UL max gain (BDA Card) dB 80 80 / DL max gain (BDA Card) dB 80 80 80 UL max gain (PRRU Card) dB +10——+20dBm input: 10 +20——+37dBm input: 0 DL max gain (PRRU Card) dB +10——+20dBm input: 10 +20——+37dBm input: 0 ATT adjust range dB MU: 0 – 30, ARU: 0 – 20 In-band ripple(P-P) dB ≤ 4 ≤ 6 ≤ 6 ≤ 6 ≤ 6 ≤ 6 Emission spur FCC FCC FCC FCC FCC FCC UL NF at max gain dB ≤ 10 System delay (BDA Card) usec ≤ 10 System delay (PRRU Card) usec ≤ 3 Input VSWR ≤ 1.5 MU Max input power (BDA Card) dBm -10 MU Max input power (PRRU Card) dBm 37 ARU Max input RF power dBm -10 1.5 INSTALLATION 1.6 WARNINGS AND ALERTS Laser Laser light can cause damage to eyes. Laser light is not visible. Viewing it directly does not cause pain. The iris of the eye will not close when viewing a bright light. Consequently, serious damage to the retina of the eye is possible. NEVER LOOK INTO THE END OF A FIBER WHICH MAY HAVE A LASER COUPLED TO IT. Radio Frequency Energies There may be situations, particularly for workplace environments near high-powered RF sources, where recommended limits for safe exposure of human beings to RF energy could be exceeded. In such cases, restrictive measures or actions may be necessary to ensure the safe use of RF energy. High Voltage The equipment has been designed and constructed to prevent practicable danger, as far as reasonably possible. Any work activity on or near equipment involving installation, operation or maintenance must be free from danger, as far as reasonably possible. Where there is a risk of damage to electrical systems involving adverse weather, extreme temperatures, wet, corrosive or dirty conditions, flammable or explosive atmospheres, the system must be suitably installed to prevent danger. Protective Earthing Equipment provided for the purpose of protecting individuals from electrical risk must be suitable for the purpose and properly maintained and used. Handling Precautions This covers a range of activities including lifting, lowering, pushing, pulling, carrying, moving, holding or restraining an object or person. It also covers activities that require the use of force or effort, such as pulling a lever, or operating power tools. Electrostatic Discharge (ESD) Observe standard precautions for handling ESD-sensitive devices. Assume that all solid-state electronic devices are ESD-sensitive. Ensure the use of a grounded wrist strap or equivalent while working with ESD-sensitive devices. Transport, store, and handle ESD-sensitive devices in static-safe environments. WARNING This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC License to operate this device. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation. The device not …
