FDDI Modules

FDDI modules are available in the following
configurations:
FDDI MMF — Connects to multimode fiber-optic
cable and provides a transmission distance of up to
2 km (1.24 mi) using 62.5-micron fiber.
FDDI SMF — Connects to single-mode fiber-optic
cable and provides a transmission distance of up to
14.4 km (8.95 mi) using 9-micron fiber.
FDDI MMF and FDDI SMF modules contain six FDDI
ports that use fiber (SC) connectors, providing a
100 Mbps FDDI connection over fiber-optic cable. The
ports support both SAS (single-attached station) and
DAS (dual-attached station) modes to provide a
maximum of six SAS connections or three DAS
connections.
Each system can accommodate up to four FDDI
modules. The modules are hot-swappable.
