وصف
وصف:
Digital Fiber Optic Repeater(FOR) adopts software wireless technology,digital filter technology and digital transmission technology, conquer the limiting disadvantage of simulate fiber optic transmission distance, satisfy the requirements of large dynamic and low noise while long distance transmission. In a situation of changeless hardware platform, Digital FOR realizes function extension of device via upgrade device software, and the way is flexible and convenient for using. Digital FOR much excellent than Simulate FOR no matter in frequency selectivity,anti-jamming ability or in function extension.
Product Category:
As per working method of frequency selection, the Digital FOR can be divided into Carrier-based Digital FOR and Wideband Digital FOR.
