Note
The MFB series single mode SFP
transceivers 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 transceiver:

4. Installing SFP Modules
4.1 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.

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 ber-optic cable type match the SFP trans-
ceiver model.
To connect to MFB-FX / MFB-TFX SFP transceiver,
use the multi-mode ber cable- with one side
must be male duplex LC connector type.
To connect to MFB-F20/TF20/F40/F60/FA20/
FB20 SFP transceiver, use the single-mode
ber cable-with one side must be male duplex LC
connector type.
Connect the ber 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, ber 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 ber-NICs or Media Converters,
set the Link mode to “100 Force” is needed.

4.2 Remove the module
1. Make sure there is no network activity by consult
or check with the network administrator. Or through
the management interface of the switch/converter (if
available) to disable the port in advance.
2. Remove the Fiber Optic Cable gently.
3. Turn the handle of the MFB module to horizontal.
4. Pull out the module gently through the handle.

Note
Never pull out the module without pull the
handle or the push bolts on the module.
Direct pull out the module with violent
could damage the module and SFP module
slot of the device.
