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 2-6.) The E3 and DS3
PLIMs both require cable CAB-ATM-DS3/E3.
