10 Gbit/S Network Interface Card , Ethernet Network Adapter Card With Specific Wavelength
The O9953 card is used as a line card in the system to implement the access and processing of one STM-64 optical interface service.
The O9953 card provides the line access and service access with the rate of STM-64. The main functions of the card are as follows:
The working principle of the O9953 card is shown as below.
