ATM Line Card Power Budget and Signal Specifications
The 4-port ISE ATM line card uses both single-mode and multimode fiber-optic cable. Signals can travel
farther through single-mode fiber than through multimode fiber. The maximum distance for installations
is determined by the amount of light loss in the fiber path. If your environment requires the light to travel
close to the typical maximum distances, you should use an optical time domain reflectometer (OTDR)
to measure the power loss.
The following sections describe the power budget and signal specifications for the optics used in each
ATM line card:
