Passive DWDM Applications
The ONS 15454 supports 18 different OC48 ELR ITU-T 200 GHz or 37 OC48 ELR ITU-T 100
GHz cards to provide you with up to 80 Gb/s of bandwidth over a single fiber. Deployed where
fiber routes are constrained, this fiber bandwidth leverages the installed fiber resources and
reduces the need to install new fiber. Matching the ONS 15454 OC48 ELR ITU-T cards with
Cisco’s ONS 15216 DWDM products or DWDM products from third party vendors greatly
expands the capabilities of the ONS 15454. Figure 9-35 shows a typical 7ft. x 19in. rack layout
for a DWDM hub site using ONS 15454 OC48 ELR ITU-T cards and third party multiplexers and
demultiplexers.
