美国科学亚特兰大公司宣布其Prisma Optical Network系列产品又添新款—Prisma数字转发机。该转发机是OC-48SONET(同步光电网)多路转发机,主要用于地区间主前端到分前端的联网和网络主干传输宽带业务。 Prisma数字转发机是传输图像频道、声音和宽带数据业务的最佳解决方案,以SONET和SDH开放标准技术为基础,通过一系列低速模拟编码器和解码器接口,以非压缩的、高质量的传输方式进行远程图像传输。 Prisma数字转发机包括1550nm对外调制光电传输机、渗铒光纤放大器、1310nm光电传输机及光电节点。它还提供插入升级模块,支持双向SONET传输,实现在一个共用的多路转发机上
American Scientific Atlanta Corporation announces that its Prisma Optical Network series of products add new -Prisma digital transponder. The transponder is an OC-48 SONET (Synchronous Optical Network) multiplexer that is mainly used for inter-regional main front-end to sub-front-end networking and network backbone transmission broadband services. The Prisma digital transponder is the best solution for transporting image channels, voice and broadband data services, based on SONET and SDH open standard technologies, through a series of low-speed analog encoder and decoder interfaces in an uncompressed, high-quality Transmission method for remote image transmission. Prisma digital transponder includes 1550nm external modulation optical transmitter, erbium-doped fiber amplifier, 1310nm optical transmitter and optical node. It also provides plug-in upgrade module, support for two-way SONET transmission, in a common multiplexer
