FDDI Connectors & Adapters

Optical Performance Distribution

Applications

The American National Standards Institute (ANSI) developed a standard that provides for flexible, robust high-performance

local area networks. This high-speed, 100 megabit per second standard is called the Fiber Distributed Data Interface (FDDI).

In support of this standard, Molex has developed its FDDI family of fiber optic connector and adapter products.

The Molex family of FDDI connectors utilize pre-polished and pre-radiused ferrules. When combined with the unique Molex

termination process, these connectors produce quick and consistent FDDI terminations. The type of port and service on the

connector is easily identified by the color coded and polarized keys provided with these connectors.

Adapters are available in a variety of mating and mounting configurations. All are made of strong and durable engineering

polymers and have either precision zirconia ceramic or polymer alignment sleeves. Polarity maintaining and color coded

keys, that are compatible with the port designation on the connector, are provided with the adapters.
