SW3
GIGABIT/FAST ETHERNET SWITCH TYPE SW3 (DIN) 24/122
USER GUIDE - M0SW3D1905Iv04 - V04 May 2019
FIGURE 13 Multimode optical fiber
2.3 100BASE-FX (MULTIMODE, ST) PORTS
In each 100Base-Fx port of this type, upon request, it should have a ST 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 13. 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.
FIGURE 13 shows the most important input and output optical power characteristics
according to the type of multimode fiber used.
All the ST type connectors have a protective cap.
