1 Overview

ZXMW SR10 is SDH family of digital microwave systems by ZTE Corporation. It leads the marketin technology innovation, network flexibility, and IP evolution.

ZXMW SR10 S340 is a comprehensive high capacity IP and Migration-to-IP network solution. Itwas designed as a native Ethernet microwave radio platform that can integrate smoothly in anynetwork, while providing a broad range of software-configurable licensed channel schemes Itsupports both data and voice transmission, typically in mobile RAN, backhaul, enterprise,government, and public safety networks.. It is optimized for combined SDH-IP operation in nextgeneration wireless networks.

ZXMW SR10 S340 supports frequency bands from 6 to 38 GHz and supports 16xE1 telephonywith 5xFE and 2xGbE data interfaces. Advanced Adaptive Code Modulation (ACM) from QPSK to

256QAM provides bandwidth range from 7 to 56MHz for 10 to 500Mbps throughputs. ZXMWSR10 S340 is developed for low-to-high capacity SDH access and transport.

1.2 Advanced TechnologyThe following advanced technologies are used in ZXMW SR10 S340 Digital microwave systemdesign.

1.2.1 FEC-Seed Solomon Technology

ZXMW SR10 S340 System adopts twice accessional FEC coding technology. To build (252, 236)RS coding which is first FEC coding, 16 byte RS code was tacked after 236 byte. This is known asRS coding External code. The second accessional FEC coding adopts Convolution Coder. This isknown as Convolution Coder Internal code. Based on this design, ZXMW SR10 S340 Systemgets more system gain with less coding length.





1.2.2 Adaptive Coding and Modulation Technology

Adaptive Coding and Modulation refers to the automatic adjustment that a wireless system canmake in order to optimize over-the-air transmission and prevent weather-related fading from

causing communication on the link to be disrupted. When extreme weather conditions, such as astorm, affect the transmission and receipt of data and voice over the wireless network, an ACM-enabled radio system automatically changes modulation allowing real-time applications tocontinue to run uninterrupted. Varying the modulation also varies the amount of bits that aretransferred per signal, thereby enabling higher throughputs and better spectral efficiencies. Forexample, a 256 QAM modulation can deliver approximately four times the throughput of 4 QAM(QPSK).

1.2.3 Hybrid & Native transmission solution

Native TDM + Native IP, High throughput, Low latency, Hitless dynamic allocation between TDMand Ethernet service

With Native solution, get optimal all-IP or hybrid TDM-IP backhaul networking - ideal for any RANevolution path.

2 Product Description

2.1 Physical Description

The ZXMW SR10 S340 radio system consists of IDU (Indoor Unit) and ODU (Outdoor Unit). TheIDU can be mounted in the standard 19” (483 mm) rack occupying 1U space for unprotectedconfiguration and one more IDU for 1+1 HSB protection. The ODU is weatherproof and can bemounted in separate or direct mode with antenna.

The radio is fully programmable in terms of capacity, modulation level, RF frequency channel, andtransmit output power level.
