The 622.08 Mbps STS-12/STM-4 or 155.52 Mbps STS-3/STM-1 transmit serial output is avaliable on TXOP/N
pins. The transmit serial output can be AC or DC coupled to an optical module or electrical interface. A
simplified DC coupling block diagram is shown in Figure 17.

:
Some optical modules integrate AC coupling capacitors within the module. AC or DC coupling is largely specific to
system design and optical module of choice.
