The TRANSITION Networks Fiber Optic Micro-ceiver (E-FRL-MC01(C)) is a compact
unit used in an Ethernet IEEE 802.3 type of network. It can be connected directly to any
Ethernet workstation, hub or AUI (Attachment Unit Interface) attachment cable.

The Micro-ceiver has an AUI (DB-15) port interface on one end and two ST type fiber
connections on the other. NOTE: An SMA type fiber connection is also available on
the Micro-ceiver E-FRL-MC01C(SMA).

USER’S GUIDE

FCC Regulations:

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the interference at his own cost.

NOTE: This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out

on the radio interference regulations of the Canadian Department of Communications.
NOTE: This equipment has been tested and found to comply with VDE Class B requirements.

Using the Fiber Optic Micro-Receiver

The fiber Micro-ceiver can be attached directly to
a fiber hub or, through another fiber Micro-ceiver,
to a terminal device or 10BaseT hub.

1. Is the power LED on the E-FRL-MC01 illuminated?

NO

• Contact Technical Support at [phone] or at (800) LAN-WANS.

YES

• Proceed to step 2.

2. Is the Link LED illuminated?

NO

• Check fiber cables for proper connection.

• Verify that TX and RX cables on media converter are connected to RX and TX ports,

respectively, on the other 10BaseFL device.

• Contact Technical Support at [phone] or at (800) LAN-WANS.

YES

• Contact Technical Support at [phone] or at (800) LAN-WANS.

• Verify that both the fiber products to be

connected are 10BaseFL or FOIRL compliant.
(The fiber port on the TRANSITION Networks
E-FRL-MC01 conforms to 10BaseFL or FOIRL
but NOT to 10BaseFB or FDDI.)

• 62.5/125 micron duplex fiber cable is
recommended.

• The maximum dBm loss for the fiber cable
should not exceed 13 dBm.

• Ensure that cable installed at transmit (TX)
connector of E-FRL-MC01 is installed at receive
(RX) connector of E-FRL-MC01 or hub at other
end of fiber cable; ensure that cable installed at
receive (RX) connector of E-FRL-MC01 is
installed at transmit (TX) connector of E-FRL­MC01 or hub at other end of fiber cable.

• Optional AUI cable assembly cannot exceed
50 meters (165 feet)..

• Connecting more than two media converters in
series is not recommended.

Troubleshooting the Media Converter

Installation Notes

If the E-FRL-MC01 fails, determine the answers to the following questions:

SQE Enable / Disable: The SQE
(Signal Quality Error) switch,
located and marked at the Micro­ceiver front, is set to ON to enable
the SQE or set to OFF to disable
the SQE. (A small screwdriver is
ideal for setting the SQE switch.)

SQE ON: Set the SQE switch to
enabled (ON) when the Micro­ceiver is connected to a terminal
device.

SQE OFF: Set the SQE switch to
disabled (OFF) when the Micro­ceiver is connected to a hub.
