Figure 3: OC-48/STM16 (and below) to OTU-1 Edge Tran-
sponder
Figure 3 shows the Niagara in an edge transponder applica-
tion. An AMCC S3474 CMOS Dual-SerDes with Continuous
mode operation provides the interface to the client side and
network side optics. In this application, the client half of the
S3474 will run down to FDDI rates (125 Mbps). The network
side of the S3474 will support the client rate plus 7% overhead
for a pure FEC application, or it will support an OTU-1 rate for
mapping into the Digital Wrapper frame.
