Preparing Network Connections
For SONET/SDH single-mode connections, use the single-mode (ST2) connector (bayonet-style
twist-lock). (See Figure 2-7.)

Warning
Invisible laser radiation can be emitted from the aperture ports of the single-mode ATM
products when no fiber-optic cable is connected. Avoid exposure and do not stare into open
apertures. This product meets the Class 1 Laser Emission Requirement from CDRH FDDI.
For E3 and DS3 connections, use the 75 ohm, RG-59, coaxial cable, CAB-ATM-DS3/E3, which has
bayonet-style, twist-lock (BNC) connectors and ferrite beads. (See Figure 2-8.) The E3 and DS3
PLIMs both require cable CAB-ATM-DS3/E3.

Caution
To ensure compliance with EMI standards, the E3 PLIM connection requires an EMI filter
clip (CLIP-E3-EMI) on the receive port (RCVR); the DS3 PLIM connection does not require this
clip.
For multimode connections, connect the multimode interface cable to the media interface cable
(MIC) connector. (See Figure 2-9.)
