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.

About the Fiber Optic Micro-ceiver™

The TRANSITION Networks AAUI to fiber optic Micro-ceiver™ P/N E-FRL-MC01A is a compact
unit used in an Ethernet IEEE 802.3 type of network. It can be connected directly to any AAUI (Apple
Attacment Unit Interface) port on a workstation or printer.

The Micro-ceiver™ complies with the Ethernet IEEE 802.3 specifications for a fiber optic inter­repeater link (FOIRL).

The Micro-ceiver has an AAUI (14 - Pin) port interface on one end and two ST type fiber connec­tions on the other. (An SMA type fiber connection is also available: Transition P/N E-FRL-MC01A(SMA).

Dimensions: Case size: 2.45” (6.2cm) x 1.75” (4.4cm) x 0.875” (2.2cm)
The AAUI cable length is 0.5 meters or 1.65 feet.

Features of the Fiber Optic Micro-ceiver

™

• External SQE enable or disable switch

• Compliant with Ethernet IEEE 802.3 specifications for fiber optic inter-repeater link (FOIRL)

• Easy to read LED indicators: Transmit (TX), Receive (RX), Jabber, Collision, Link and Power

• Two year warranty

• Made in the USA

• No external power required

• UL listed; FCC class A compliant

SQE Enable / Disable

The SQE (Signal Quality Error) selection switch can be turned ON to enable the SQE or it can be
turned OFF to disable the SQE. The SQE switch is located and marked on the front of the Micro-ceiver.
(Pictured on the front page of the installation guide). (A small regular screw driver is ideal for switching
the SQE switch ON and OFF).

SQE Enable Position (ON): The Micro-ceiver needs to be enabled (turned ON) when it is

connected to a workstation or DTE.

SQE Disable Position (OFF): The Micro-ceiver needs to be disabled (turned OFF) when it is

connected to a hub.

Using the Fiber Optic Micro-ceiver

™

The fiber Micro-ceiver™ is attached to the AAUI port of the workstation or printer. The fiber con­nection is shown below.

The illustration shows how to inter connect two AAUI to fiber optic Micro-ceivers™. In the dia­gram, the left transceivers transmit port is connected by fiber to the receive port on the right transceiver.
The right transceivers transmit port is connected by fiber to the left transceivers receive port. (Use the
same configuration, transmit to receive, if you are connecting a fiber optic transceiver to a fiber optic
hub with ST connections).

Using the AAUI to Fiber Optic Micro-ceiver™(Continued)

The AAUI to fiber Micro-ceiver™ was tested and designed for use with 62.5 / 125 µm multimode
fiber optic cable. The fiber segment can be up to 2000 meters (6600 feet) long which meets the FOIRL
standards.

If fiber optic cable is already in place, other fiber opic multimode cable types that can be used
include: 50/125 µm, 85/125 µm, 100/125 µm. After determining which fiber cable is going to be uti­lized, do not exceed the maximum distance ratings for that type of fiber cable. (Check with your local
distributor for distance limitations or call TRANSITION Networkss Technical Support Department. The
phone number is on the back of this installation guide).
