• ODUflex containers map services, in 1.25G increments (such as FC400) more efficiently into OTN rather than dedicating a full 2.5G (ODU1) or 10G (ODU2) per service.

• Asynchronous Mapping Procedure (AMP)
Flexibility to limit BW of each client to desired amount with 1.25G/5G granularity • Subscriber purchases only the amount of BW needed • Providers can limit the BW entering their network per the SLA
• Bit-synchronous Mapping Procedure (BMP)
• Generic Framing Procedure (GFP)
• Generic Mapping Procedure (GMP)
• Idle Mapping Procedure (IMP)
Further increase network bandwidth efficiencies with a right-sized ODUflex container
