Introduction
OC-48 small form-factor hot-pluggable modules (SFP) allow designers to place a large number of OC-48 links in a relatively small amountof space. As the density increases, adjacent channels are more likely to interfere with each other. When the Si5110 or Si5100 OC-48 transceivers are used to receive and transmit through the SFP module, it is necessary to minimize the adjacent channel coupling in order to meet the transmit jitter generation requirements.
