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 ber-optic cable type match the SFP trans-

ceiver model.

To connect to MFB-FX SFP transceiver, use the

multi-mode ber 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 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.
