SWT
GIGABIT/FAST ETHERNET SWITCH TYPE SWT 25/137
USER GUIDE - M0SWTA1903Iv09 - V09 March 2019
FIGURE 15 shows the most important input and output optical power characteristics
according to the type of multimode fiber used.
All the ST or SC type connectors have a protective cap.
2.4 100BASE-FX (MULTIMODE, LC) PORTS
In each 100Base-Fx port of this type, it should have a LC type connector. The cable
required to make the connection should be a fiber optic cable made up of two multimode
optical fibers, one to transmit data and the other to receive it. Each of the fibers should be
125 μm in diameter. The core and the cladding of the fiber are included in this diameter, as
can be seen in FIGURE 15. The core can be 50 μm or 62.5 μm in diameter. The
wavelength used should be 1300 nm (multimode). The cable length should not be more
than 2 km.

2.5 100BASE-LX (SINGLEMODE, LC) PORTS
In each 100Base-Lx port of this type, it should have a LC singlemode type connector. The
cable required to make the connection should be a fiber optic cable made up of two
singlemode optical fibers, one to transmit data and the other to receive it. Each of the fibers
should be 125 μm in diameter. The core and the cladding of the fiber are included in this
diameter. The core is 9 μm in diameter. The wavelength used should be 1300 nm
(singlemode). The cable length should not be more than 10 km.
