Mode Band
The mode band shown in the above table is a quality indicator of the multimode
optical fibre 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)
multiplied by the maximum transmission distance. The size 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. Straight-through UTP cable is used for connecting the LIM module to other
modules (MP40, MGI, 4DSL). Crossover UTP cable is used for connecting only
the LIM (or PLIM) module to another LIM (or PLIM) module.
