1. Overview

Caution

MFB MFB

Thank you for purchasing PLANET MFB family SFP 100Base-FX Fast Ethernet module. The MFB family SFP Fast Ethernet module can install into PLANET Switch products with 100Base-FX SFP interface. The distance can be extended from 2km (MM) up to 60 kilometers (Single-mode, LC).

3. Check List

Your MFB carton should contain the following items:

4-2 1-Port 100Base-BX WDM SFP Modules – MFB-FA20 / MFB-FB20

Features:

Comply with IEEE 802.3u Fast Ethernet standard

1 x 100Mbps ber port (Single LC ber connectors)

Plug and Play Installation

MFB-FA20 provides distance up to 20km over

9/125μm single mode ber cable

MFB-FB20 provides distance up to 20km over

9/125μm single mode ber cable

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 inline 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 hotswappable. 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 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 workstation or a Media Converter.

3. Check the LNK/ACT LED of the SFP slot of the switch / converter. Ensure that the SFP transceiver is operating 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.

5.2 Remove the module

MGB/MFB

Caution

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.

Figure-2 Pull Out the SFP transceiver

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.
