The Optical Internetworking Forum (OIF) is a non-profit industry organization founded in 1998. It promotes the development and deployment of interoperable computer networking products and services through implementation agreements (IAs) for optical networking products, network processing elements, and component technologies.

OIF creates benchmarks, performs worldwide interoperability testing, builds market awareness and promotes education for optical technologies. The Network Processing Forum merged into OIF in June, 2006.


Implementation agreements are based on requirements developed cooperatively by end users, service providers, equipment vendors and technology providers in alignment with worldwide standards, augmented as necessary. This is accomplished through industry member participation working together to develop specifications for external network element interfaces, software interfaces internal to network elements and hardware component interfaces internal to network elements.

OIF sponsors a technical committee and a market awareness and education committee. The technical committee has working groups:

  • The Architecture and Signaling Working Group develops agreements related to architecture and signaling from service provider requirements.
  • The Carrier Working Group assembles functional requirements and guidelines for optical networking products.
  • The Interoperability Working Group defines testing methodologies, carries out proofs of concept, evaluates multi-vendor interoperability and contributes technical leadership for interoperability trials. Test criteria and test methods are defined with support of the source technical working group.
  • The Operations, Administration, Maintenance, and Provisioning working group focuses on deployment issues. The scope includes but is not limited to a) planning, engineering and provisioning of network resources; b) operations, maintenance or administration use cases and processes; and c) management functionality and interfaces for operations support systems and interoperable network equipment. Within its scope are Fault, Configuration, Accounting, Performance and Security Management (FCAPS) and Security.
  • The OIF Physical and Link Layer Working Group develops implementation agreements related to physical and data link layer interfaces between optical internetworking elements and between their internal components.
  • The OIF Physical Layer User Working Group develops requirements and guidelines for components, modules, subsystems and communication links thus providing common direction to the vendor community and other OIF working groups.
