SW3
GIGABIT/FAST ETHERNET SWITCH TYPE SW3 (DIN) 25/122
USER GUIDE - M0SW3D1905Iv04 - V04 May 2019
2.4 100BASE-FX (MULTIMODE, LC) PORTS
In each 100Base-Fx port of this type, upon request, 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 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 LC type connectors have a protective cap.
2.5 SFP PORTS
The bays available in the front plate of the equipment admit the installation of SFP (Small
Form Factor Pluggable) modules, which provide optic Gigabit Ethernet interfaces to the
switch; the characteristics of the fiber optic to be used, as well as the type of connector, will
depend on the SFP model used. See the available modules in section 1.4.3.
Bays have a protective cap.
Inserting procedure of an SFP module
The inserting procedure of an SFP module is the following:
1. Remove the protective packaging of the SFP module.
2. Check that the SFP module is the correct one for your network configuration.
3. Hold the module between your thumb and forefinger.
4. Insert the module into the corresponding SFP slot on the front panel of the equipment.
5. Remove the protective caps from the optical ends of the module.
6. Insert the fibers, in the optical ends of the module, keeping in mind the TX and RX data
transmission directions (see FIGURE 14).
