摘要
广电微波电路在确保广播电视节目安全播出和国家信息安全中有着重要的战略地位,是抗拒自然灾害和抵御人为破坏的重要传输方式。微波首台——地球站SDH电路是甘肃广电建设的第一条SDH数字微波电路,它的建成保证了地球站上星节目信号源的稳定和安全,提高了广播电视节目信号传输质量,实现广播电视高清节目信号的传输。通过MSTP技术的运用,将SDH数字微波传输平台建设成为支持多业务传送、组网灵活、带宽利用率高的IP化传输网络,为今后新业务的推广打下坚实的基础,为甘肃省全线路的SDH电路建设提供了成熟经验和可靠的依据。
Broadcast television microwave circuit in ensuring the safety of radio and television programs broad-cast and national information security is an important strategic position resisting natural disasters and vandalism and an important way of transmission.Microwave station-earth station synchronous digital hierarchy (SDH) circuit is Gansu Radio and television building first SDH digital microwave circuit,it built ensures the earth sta-tion Star program source of stability and security,improve the quality of signal transmission of radio and TV programs,HD broadcast and TV program signal transmission.SDH digital microwave transmission platform construction to support multi service transport through the application of MSTP technology and flexible networ-king,bandwidth utilization and high IP network transmission,for the future new business promotion and lay a solid foundation,for the province total line of synchronous digital hierarchy (SDH)circuit construction pro-vides mature experience and reliable basis.
