Table 5-5 provides technical information about the laser diode on the ATM OC-12c single
mode media card:
Attaching ATM media cables
GRF ATM media cards are available in both multimode and single mode.
A multimode card requires duplex SC fiber optic cable and has a distance limitation of
approximately two kilometers. A single mode card requires simplex SC fiber optic cable and
has a distance limitation of approximately 15 kilometers. Figure 5-5 shows both types of
cables.
Excess cable lengths should be bound in a figure-eight pattern. Do not wind excess cable into
circular coils.

Not only are fiber cables easier to damage than coax and other types of cables, but the damage
is harder to detect.
