1.2 Cyan Z33 Shelf
The Cyan Z33 Industrial Temperature (I-Temp), 400 Gbps packet-optical transport shelf is a compact,
cost-effective member of the Z-Series multi-layer transport networking platforms. The system provides
multi-layer add/drop multiplexing (MADM) and transport functions in one fully integrated system. The
system’s shared mesh protection provides full protection and sub-50 ms restoration for all services.
The Z33 shelf is a smaller version of the Z77 chassis intended for lower capacity and more cost-sensitive
edge applications. Z33 deployments enable service providers to scale packet services, leverage existing
services and infrastructure. It also optimizes their networks with multi-layer networking using 2.5G CWDM
and 10G DWDM transport.
A Z33 system equipped with Z-Series interchangeable trunk-side modules can be configured to support a
variety of network functions, including:
• Fully Reconfigurable Optical Add Drop Multiplexer (ROADM) with Optical-Optical-Optical
(OOO) switching and optical pass-through.
• Standalone SONET or SDH aggregation and transport.
• Packet switching providing advanced Layer 2 Ethernet services, access grooming and connection
oriented Ethernet.
• Efficient G.709 OTN grooming of the above services on to 10G multiservice wavelengths.
• Multi-channel DWDM with full optical add/drop multiplexing.
• CWDM channels of up to eight 2.5G wavelengths.
• Aggregation, grooming and STS-1 level switching of SONET/SDH and GbE services from existing
Ethernet switches, routers, DSLAMs, DLC/BLCs and third-party products.
• Transponding Gigabit Ethernet and OC-3/12/48 SONET STM-1/4/16 SDH services.
• Any combination of the above.
