Fibers connected using SFIU boards


Each port on the SFIU board supports bidirectional transmission. It can receive or transmit a signal depending on the position of the SFIU board. The optical ports LINE1, LINE2, SYS1, and SYS2 can be used to transmit or receive signals on the main optical path.

Fiber connections of TN12OAU boards
One multiplexed optical signal received at the IN port is sent to the EDFA optical module. The EDFA optical module amplifies the optical power of the signal and locks the gain of the signal. The signal is then transmitted to the DCM board through the TDC port for dispersion compensation. Then, the signal is sent back through the RDC port. The amplified multiplexed signals are output through the OUT port. The multiplexed signal can also be input through the VI port and output through the VO port after the optical power is adjusted. Then, the IN port receives the multiplexed signal sent from the VO port.

OSC boards that can work together with the SFIU board
The OSC board that works with the SFIU board must be ST2, because the ST2 board supports either the 1511 nm or 1494 nm pluggable optical module. When the ST2 board works with the SFIU board, the operating wavelength of its RM1/TM1 port is 1511 nm and that of its RM2/TM2 port is 1491 nm. The SFIU board converges these two monitoring signals so that they can be transmitted over one optical fiber, implementing the commissioning-free and compensation-free functions defined in IEEE 1588v2.

Whether the HBA board can be used together with the SFIU board
No. The HBA board must be used together with the TN13FIU02 board.

Types of fibers used to connect the HBA board
LSH/APC connectors and fibers are used on the OUT port of the HBA board, and LC connectors and fibers are used on the IN port of the HBA board.
