Product description
DES801 - SDH / PDH BER Analyzer is the latest portable Tester in our company, using ultra-large-scale integrated circuits, combining my company self-developed FPGA circuits and software developed from. It has many highlights, such as small size, low watt loss, powerful, high reliability, etc. It can evaluate the transmit performance to DES801-SDH/PDH. It is t an indispensable tool to installation, network debugging, and acceptance and maintenance.
