Connector Types
Bay Networks provides the following connector types:
• Attachment Unit Interface (AUI): A 15-pin D-type connector that connects
equipment to the Ethernet network through a transceiver
• CCITT Series (V.28, V.35): CCITT-recommended V.10 (unbalanced) and V.11
(balanced) standard connectors
• DTE to DCE interface (X.21): CCITT-recommended DTE to DCE
synchronous/public switched network connector
• Fiber Channel (FC): Threaded, straight-tip, coaxial or fiber optic connectors
• Fixed shroud duplex (FSD): Jack-type, dual fiber optic connector for use in
FDDI networks
• Media access unit/multistation access unit (MAU): LAN wiring concentrator
used in token ring networks
• Recommended Standard (RS-232-C, RS-449/RS-422): EIA standard
connectors for use with DTE and DCE devices
• Registered Jack Series (RJ-45; RJ-48): 8-position, FCC-registered data plugs
• Subscriber Connector (SC) duplex: Jack-type, dual fiber optic connector for
use in FDDI networks
• Spade terminals: Flat, U-shaped connectors typically used for T-carrier line
connection
• Straight-tip (ST): Bayonet coaxial or fiber optic connectors

igure 1-1 shows a sample of connectors in cable assemblies for Bay Networks
router hardware platforms.
Note: Many types of fiber optic connectors include a dust cover. (Dust
obstructs or attenuates optical signals entering or leaving the cable through the
connector.) Be careful not to lose the dust cover when you attach a fiber optic
cable connector to its counterpart connector. Replace dust covers when you
detach a fiber optic cable from any local device.
