随着经济水平的提高和通信科技的发展,光纤传输的普及率日益增长。无论是中等市县的本地网规划,还是无线基站扩容或开发新的用户群,光纤传输都是首选方案。格林威公司进入传输设备市场只有一年时间,但它开发的二、三次群点对点设备A120.A480及APDH设备显示其技术实力。 “桌面化”是其光传输设备的一个显著特点,从120路容量的设备开始,该公司就率先推出4.5cm高度的标准机型,其中一块单板,给人以耳目一新的感觉。之后又推出了A480机型,仍然是单板结构,IU的机箱,典型的桌面机,但容量却是三次群,而且公务电话、监控、数据口等功能一应具全。
With the improvement of economic level and the development of communication technology, the penetration rate of optical fiber transmission is increasing day by day. Whether it is a mid-sized county local network planning, or expansion of wireless base stations or develop new user groups, optical fiber transmission is the preferred program. Greenway entered the transmission equipment market for only a year, but the A120.A480 and APDH devices it developed for the second and third order groups showed its technical strength. “Desktop” is a notable feature of its optical transmission equipment, starting with a 120-way capacity device, the company pioneered the 4.5-cm-high standard model, one of which gives a fresh look. After that, the A480 was introduced. It is still a single-board structure, IU chassis, and a typical desktop machine. However, the capacity is three times larger and the functions of official telephone, monitoring and data port should be full.
