HUAWEI RTN 600 series IP microwave radio OptiX RTN 620 OptiX RTN 610
The OptiX RTN 600 series TDM/hybrid integrated radio transmission system (OptiX RTN 600 for short) is a digital microwave transmission system for data packets. The system provides end-to-end transmission from the access layer to the backbone layer and can work with optical network equipment for end-to-end service grooming and unified network management. With the evolution from TDM to IP, IP-based microwave transmission solutions have become a trend. The OptiX RTN 600 helps smooth evolution from TDM microwave transmission to IP-based microwave transmission, saving network construction and operation costs. The OptiX RTN 600 is available in two models, the OptiX RTN 620 and the OptiX RTN 605.
Features
RTN 620 FeaturesThe air interface of the OptiX RTN 620 supports 7MHz to 56MHz channel bandwidth and QPSK to 256 QAM modulation mode. The TDM air interface is flexibly configurable from 4E1 to 75E1; while the throughput of native Ethernet service is flexibly configurable from 10 Mbit/s to 400 Mbit/s.
With the design of single-device multiple RF directions and the networking microwave equipments, the OptiX RTN 620 delivers more flexible ring networking (PDH/SDH-Ring) and full timeslot cross-connection to any direction is available. Featuring quick service provision and adjustment, the OptiX RTN 620 decreases the number of DDF racks, external cable connectors, and IDU service interface units, while omitting the external ADM equipment.
When the air interface link works properly (for example, in sunny days), a higher modulation mode is adopted to provide high-bandwidth transmission capabilities through the adaptive modulation (AM). This helps reduce the capital expenditure (CAPEX) by making full use of the bandwidth resources. When the quality of the air interface link degrades (for example, in heavy rain or heavy fog), a lower modulation mode is adopted to increase the anti-fading capabilities. This guarantees high-quality data transmission for key users. Making full use of frequency spectrum resources, the OptiX RTN 620 helps greatly reduce TCO.
Combining cross polarization interference cancellation (XPIC) with the same channel dual polarization (CCDP) technology under the TDM mode, the OptiXRTN 620 doubles the transmission capacity under the same channel condition.
The OptiX RTN 620 boasts sound protection mechanism, which includes 1+1 power protection; 1+1 and N+1 protection in TDM mode configuration; linear multiplex section protection between optical transmission link and STM-1 link; and two-fiber bi-directional multiplex section protection ring of the STM-4 optical link. In TDM mode, the OptiX RTN 620 supports SNCP for E1 services and ERPS protection, that is, hybrid ring for data services.
RTN605 Features
The RTN 605 is applied in edge network. Supporting pure E1 and Eth service,RTN 605 is self-adaptive, highly integrated, and easy to install, maintain and troubleshoot, while its air interface is compatible with RTN620.
The RTN 605 can accommodate E1, FE, and GE services, meeting the access requirements of GSM/UMTS/WiMAX networks and various types of services can co-exist. In addition, native Ethernet services and TDM services are transmitted efficiently over the air interface with the capacity reaching up to 80 Mbit/s.
All service ports of RTN 605 support clock synchronization, meeting the requirements of BTS/NodeB for clock signals.
The RTN 605 also has the following features:
Rich data features: Ethernet OAM, CoS, flow control, and LAG
Multi-level protections: network-level, link-level, and equipment-level protections
Compact design: high integration, small footprint, and low power consumption
Simplified deployment: planned and installed together with wireless equipment, thus simplifying the deployment
Easy to operate and maintain: E2E network management for easy operation and maintenance
