Cabling the ATM
Connectors
You can cable the ATM connections using either single-mode or
multi-mode optical fiber cables for the OC3 connectors or 75-ohm
coaxial cables for the Coax (DS3/E3) connectors.
Either the OC3 or Coax (DS3/E3) connectors can be used, but not at the
same time.
Cabling the ATM OC3 Connectors
You can cable one or two OC3 connectors using single-mode or
multi-mode OC3 optical fiber cables as shown here.
WARNING: Optical Safety. Under normal viewing conditions there is no
hazard from the Transmit LED. It is recommended however that the LED is
not viewed through any magnifying device while it is powered on. It is
advisable that the fiber TX port and fiber cable ends are never viewed
directly when powered on.
