2.15 FLX-216i Multi-Rate OTN Muxponder Module
The Cyan Z-Series FLX-216i is a multi-rate OTN muxponder I-Temp module. The FLX-216i module is a
highly scalable OTN switching and muxponder optimized for deployments in network transport
applications. The environmentally hardened FLX-216i module provides two XFP-based OTU2 ports and
sixteen SFP-based client ports. The SFP ports support the following service interfaces:
• Optical GbE
• OC-3/12/48
• STM-1/4/16
The FLX-216i module provides OTN-level multiplexing of GbE, OC-3/STM-1, OC-12/STM-4, and
OC-48/STM-16 signals into two OTU2 signals. OC-48/STM-16 is mapped to ODU1 (2.5G). OC-3/STM-1,
OC-12/STM-4, and GbE are mapped to ODU0 (1.25G). The minimum cross-connect level is ODU0. There
is a maximum of eight ODU0 per 10G trunk interface. A maximum of eight OC-48/STM-16 interfaces can
be mapped to 2 x OTU2 (20G).
The FLX-216i module also provides non-blocking OTN cross-connect function across all the ports on a
module. The cross-connect function is performed at the ODU0 and ODU1 levels. Trunk port to trunk port
cross-connections are also supported.
The FLX-216i OTN muxponder module provides the following features and benefits:
• Aggregation and transport of Ethernet and SONET/SDH over the same wavelength.
• Pluggable optics provides for DWDM applications and flexibility in optical module reach.
• High-capacity 60 Gbps non-blocking OTN (ODU0/ODU1) cross-connect fabric capacity ensures
scalable performance.
• High-density design is optimized for edge applications.
• Environmentally hardened for deployment in remote cabinets.
Note: Facility protection and equipment protection configured with a protected card pair
interconnected across the backplane is not supported.
The graphic below shows the FLX-216i trunk and client interfaces functional block diagram and the OTN
muxponder function.
