4.1 App 1: OC-192/STM-64/10GbE (10G λ) transport
In this application, the Cyan Z33 shelf or the Cyan Z77 transports 10 Gbps signals. The system transponds
the OC-192/STM-64 or 10 GbE signals, maps to OTU2 and specific wavelengths using DWDM XFPs. In
intermediate sites, it provides optical-electrical-optical (OEO) regeneration. The system would contain the
DTM-8 and LAD-4/A or LAD-8/A/E/i/X cards depending on the number of waves and distances required.
Its primary purpose is to transport 10G signals from point A to B.
All traffic is optical-electrical-optical and hence, the express traffic needs to be regenerated with the DTM-8
in a pass-through node. In a protected ring, OEO regeneration in a transit node can use a single DTM-8 card
(not a protected set) since the opposite side of the ring provides protection.
The graphic below shows an example of a four-wave 10G transport application using LAD-4 and/or
LAD-4A modules.
