Single Mode to Multimode Retiming
Media Converter
• Stand-Alone Media Converter
• Gigabit Ethernet
Transition Networks SFMFF13xx-28x series
media converters extend multimode
interfaces over gigabit Ethernet fiber optic
cable.
Unlike most gigabit Ethernet media converters, which allow only two media
converters in series, the SFMFF13xx-28x has a retiming/reshaping feature that
makes it possible to connect any number of media converters in series.

Installation -- Continued
Set the 4-Position Switch
• The 4-position switch is located on the side of the media converter.
• Use a small flat-blade screwdriver to set the recessed switches.
Fiber Auto-Negotiation (Switch 1)
up = Enable fiber Auto-Negotiation for both the single mode and the
multimode ports.
When fiber Auto-Negotiation is
enabled:The pause feature can be set
using switches 3 and 4. (See page 4).
down = Disable fiber Auto-Negotiation for both the single mode and the
multimode ports.
When fiber Auto-Negotiation is
disabled:Switches 3 and 4 will not
function. The media converter adopts
the pause setting from the end device
at the other end of the fiber cable.
NOTE: All devices in the network, including the end devices, must have
Auto-Negotiation enabled, or all devices must have Auto-Negotiation
disabled. Otherwise, the devices in the network will not link up.

Link Pass-Through (Switch 2)

down = Disable Link Pass-Through.
The Link Pass-Through feature allows the media
converter to monitor both fiber RX (receive) ports for
loss of signal. In the event of a loss of an RX signal
on one media port, the media converter will automatically disable the TX
(transmit) signal of the other media port, thus, “passing through” the link loss.

No Pause
• Pause feature is disabled.
Transmit Only:
• SFMFF13xx-28x can transmit and the
link partner can receive the pause
signal.
Transmit and Receive:
• Both the SFMFF13xx-28x and the link
partner can send and receive the
pause signal.
Receive Only:
• The SFMFF13xx-28x can receive and
the link partner can transmit the
pause signal.
Installation -- Continued
Pause (Switches 3 & 4)
The pause feature can improve network performance by allowing one end of
the link to signal the other to discontinue frame transmission for a set period
of time to relieve buffer congestion.
To properly set the pause feature in the network, the link partner (i.e., the
device to which the SFMFF13xx-28x is linked) must also have comparable
pause switches. If the link partner does not have the pause feature, disable
the pause feature on the SFMFF13xx-28x media converter.
The SFMFF13xx-28x has four pause
options (listed below). To the right of each
option, a drawing shows the switch
settings for the SFMFF13xx-28x and the
link partner.

Troubleshooting
If the media converter fails, isolate and correct the fault by determining the
answers to the following questions and then taking the indicated action:
1. Is the PWR (power) LED illuminated?
NO
• Is the power adapter the proper type of voltage and cycle frequency
for the AC outlet? (See “Power Supply” on page 8.)
• Is the power adapter properly installed in the media converter and in
the outlet?
• Contact Technical Support. US/Canada: 1-800-260-1312,
International: 00-1-952-941-7600.
YES
• Proceed to step 2.
2. Are the Auto-Negotiation switches on the network devices set
such that all are set to “enable” or all are set to “disable”?
NO
• Set the Auto-Negotiation switches on all of the devices (including the
end devices) so that all are set to “enable” or all are set to “disable.”
• Contact Technical Support. US/Canada: 1-800-260-1312,
International: 00-1-952-941-7600.
YES
• Proceed to step 3.
3. Is the LKS (link, single mode) LED illuminated?
NO
• Check the single mode fiber cables for proper connection.
• Verify that the TX and RX cables on the media converter are
connected to the RX and TX ports, respectively, on the other device.
• Contact Technical Support. US/Canada: 1-800-260-1312,
International: 00-1-952-941-7600.
YES
• Proceed to step 4.
4. Is the LKM (link, multimode) LED illuminated?
NO
