OIF Electrical Standards Benefits
Enables “Best-In-Class” selection of devices that
interoperate

SERDES
FEC
Framers
Traffic Management
Fabric Interfaces
System vendors can choose their favorite feature
sets and mix and match components as needed
OIF Electrical Standards Benefits
(continued)
With interoperable standards, vendors can

•
•
•
Mix and Match “best of breed” components
Minimize the engineering to connect components
Reduce time to market
Enable customization using programmable logic for key
components
System Design Example
A systems vendor wanting to build an OC-768
switch with OIF standards can select:
A customized traffic manager from FPGA Vendor X
• A framer from ASSP vendor Y
• A SERDES module from Optical Vendor Z
FPGA Vendor X

Optical
Vendor Z
ASSP
Vendor Y
OIF Electrical Standards Silicon Solutions
A variety of Silicon implementation solutions are
available, including:
ASSP + FPGA
ASIC
System vendors do not get locked in to a
proprietary solution
OIF-compliant chips interoperate effectively to
enable “best of breed” system solutions
