a: The OptiX RTN 610 supports four STM-1 interfaces when it functions as a pure optical transmission system.
b: The OptiX RTN 620 supports 10 STM-1 interfaces when it functions as a pure optical transmission system.
2.5 Flexible Modulation
The modem of the OptiX RTN 600 supports QPSK, 16QAM, and 128QAM. You can
select the modulation mode as required.
2.6 Automatic Transmit Power Control
The OptiX RTN 600 supports the automatic transmit power control (ATPC) function.
The ATPC function enables the output power of the transmitter to automatically trace
the level fluctuation at the receive end. This reduces the interference with neighboring
systems and residual BER.
