Mode Band
The mode band shown in the previous table is a quality indicator of the multimode
optical fiber related to the transmission speed. Its unit is generally MHz. Km, and
is proportional to the value of the bit rate of the optical signal (the on-off speed) X
the maximum transmission distance. The largeness of this value means the high
optical signal with high bit rate can be transmitted. Each mode band is
standardized also in the use of short wave and long wave laser.
Categories of UTP Cable
UTP Cables are classified into Straight-through UTP cable and Crossover UTP
cable. The Straight-through UTP cable is used for connecting the LIM module of
OfficeServ 7400 system to other modules (MP40).
The Crossover UTP cable is used for connecting only LIM (PLIM) module to LIM
(PLIM) module.
