Determining Cable Distances
ATM
The maximum distances for asynchronous transfer mode (ATM) fiber-optic
network connections are determined by the transmitter output power, receiver
sensitivity, and type of optical source. Table 2-1 lists the maximum transmission
distances for multimode fiber (MMF). Table 2-2 lists the optical specifications for
single-mode fiber (SMF) cables.
Table 2-1 ATM OC-12 Optical Specifications for MMF Cables
Characteristic Specification
Optical source LED
Wavelength 1300 nm
Transmitter output power –19 to –14 dBm
Receiver sensitivity –26 to –14 dBm
Maximum cabling distance 1640 ft (500 m)
Table 2-2 ATM OC-12 Optical Specifications for SMF Cables
Characteristic Specification
Optical source Laser
Wavelength 1300 nm
