摘要

泰国的新SDH网络是一个综合网络，其中使用不同的媒体，如OFC和无线电中继来传输SDH有效载荷。本文介绍了SDH无线电的路由特性和路由图等性能。无线电系统采用128 QAM调制，上6ghz频带，40mhz信道间隔用于STM-1信号。信道安排符合ITU-R F384-6标准。对于STM-1信号，必须考虑包含SOH处理的基带接口，按照Rec. ITU-R F,750-3。系统的性能目标是基于rec - TU-RF。11891和iec - t G.826。

SDH radio routes backup in Thailand

The new SDH network in Thailand is an integrated network, where different media such as OFC and radio relay is used to transmit the SDH payloads. This article describes the SDH radio route characteristics and performance such as route map. The radio system use 128 QAM modulations with upper 6 GHz band, 40 MHz channel spacing for STM-1 signal. The channel arrangement is in accordance with Rec. ITU-R F384-6. Baseband interfaces inclusive the SOH processing has to be considered for STM-1 signals in accordance with Rec. ITU-R F,750-3. The system performance objectives is based on the rec. TU-RF.11891 and rec. ITU-T G.826.
