Caution
The MFB series single mode SFP trans-
ceivers provide the optical power budget
from 15 dB to 30dB. When shorter
distance of single-mode fiber cables is
used, you might need to insert an in-
line optical attenuator in the link to avoid
overloading the receiver:

5. Installing SFP Modules
5.1 Installing the SFP transceiver
The sections describe how to insert an SFP transceiver
into an SFP slot.
The SFP transceivers are hot-pluggable and hot-
swappable. You can plug-in and out the transceiver to/
from any SFP port without having to power down the
Switch/Media Converter. As the Figure -1 appears.
MFB MFB
Figure 1 Plug-in the SFP transceiver
Before connect the other switches, workstation or Media
Converter.
1. Make sure both side of the SFP transceiver are with
the same media type or WDM pair, for example:
100Base-FX to 100Base-FX, 100Base-BX20-U to
100Base-BX20-D.
2. Check the fiber-optic cable type match the SFP trans-
ceiver model.
To connect to MFB-FX SFP transceiver, use the
multi-mode fiber cable- with one side must be male
duplex LC connector type.
To connect to MFB-F20/F40/F60/FA20/FB20 SFP
transceiver, use the single-mode fiber cable-with
one side must be male duplex LC connector type.
Connect the fiber cable
1. Attach the duplex LC connector on the network cable
into the SFP transceiver.
2. Connect the other end of the cable to a device –
switches with SFP installed, fiber NIC on a worksta-
tion or a Media Converter.
3. Check the LNK/ACT LED of the SFP slot of the switch
/ converter. Ensure that the SFP transceiver is oper-
ating correctly.
4. Check the Link mode of the SFP port if the link failed.
Co works with some fiber-NICs or Media Converters,
set the Link mode to “100 Force” is needed.
