Chapter 2: Z-Series Line Cards,
Modules, Optics, and Optical
Protection
This section describes each Cyan Z-Series line card, related XFP/SFP transceivers, Z-Series modules,
optical protection groups, and the Optical Protection Switch.
Cyan Z-Series systems provide an effective and economically efficient approach to scaling network
capacity while simplifying planning and operations. Optimized for packet and the transition of TDM to
packet, the Z-Series platforms support advanced Ethernet switching and transport over connection-oriented
Ethernet (COE), SONET/SDH, or wavelengths.
Recognizing the continuing role of TDM in many networks, the Z-Series platform optionally supports
advanced SONET/SDH aggregation and transport functionality. Rounding out support for wholesale,
wavelength services and the need to muxpond and transpond certain services, the Z-Series supports a
complete range of transport requirements. Driven by IPTV, VOD, 2/3/4G wireless backhaul, carrier
Ethernet and scaling Internet services, the Z-Series grooms services into discrete high-capacity 10G
wavelengths. As services scale, the Z-Series platform provides the option to transport multiple 10G
wavelengths per fiber using Dense Wavelength Division Multiplexing (DWDM). The Z-Series DTM-100G
module provides 100G transport services. The DTM-100G is fully compatible with existing Z-Series
DWDM components including LAD modules and WSS ROADM modules. This allows the mixing of 10G
and 100G waves over the same fiber.
Addressing the multi-layer aspect of evolving networks, the Z-Series provides multi-layer add/drop
multiplexing (MADM) and transport functions in one fully integrated system, supporting:
• GbE and 10GbE switching and transport
• SONET/SDH aggregation and transport
• OTN (digital wrapper) functionality
• 100G DWDM transport
• 10G DWDM transport
• 2.5G CWDM transport
• Multi-layer optimization and management
