 NOTE:This board can be used only in an independent subrack, but not in a master or slave subrack.


The SF64 board is a line board. The SF64 board can be used on the OptiX OSN equipment to transmit and receive STM-64 FEC optical signals. The SF64 board converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SF64 board converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

Figure 1 shows the application of the SF64 board. The SF64 boards can form a ring network or a chain network in the system.Figure 1 Networking and application of the SF64 board
