C-UL Listed (Canada)
CISPR/EN55022 Class A

FCC Regulations

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 installed and 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 the user’s own expense.

Canadian Regulations

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.

Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites applicables
aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le ministère des Communications du Canada.

European Regulations

Warning

case the user may be required to take adequate measures.

Achtung !

Dieses ist ein Gerät der Funkstörgrenzwertklasse A. In Wohnbereichen können bei Betrieb dieses Gerätes
Rundfunkstörungen auftreten, in weichen Fällen der Benutzer für entsprechende Gegenmaßnahmen
werantwortlich ist.

Attention !

Ceci est un produit de Classe A. Dans un environment domestique, ce produit risque de créer des
interférences radioélectriques, il appartiendra alors à l’utilsateur de prende les measures spécifiques
appropriées

The TRANSITION Networks J/FE-CF-01 series Fast Ethernet™ media
converters connect either unshielded or shielded 100BASE-TX twisted-pair
copper cable to 100BASE-FX multimode fiber-optic cable.

The AutoCross™ feature allows either straight-through (MDI) or crossover (MDI-X)
cables to be used when connecting to 100BASE-TX devices, such as hubs,
transceivers, or network interface cards (NICs). AutoCross™ determines the
characteristics of the cable connection and automatically configures the unit to
link up, regardless of the cable configuration.

The LinkALERT™ feature allows the J/FE-CF-01 media converter to pass 100BASE­TX side link faults to the

100BASE-FX side and to pass 100BASE-FX side link faults

to the 100BASE-TX side.

Full-Duplex Network

To calculate the round trip delay (in bit-times) in a half-duplex Fast
Ethernet™ network collision domain, find the longest path in the collision
domain. Calculate the round trip
delay for each cable segment in the
collision domain by multiplying the
length of the cable (in meters) by the
delay per meter (in bit-times (BT)).
Calculate the total round trip delay
by taking the sum of all the cable
delays plus station (DTE) and
repeater delays. If the result is less than or equal to 512 bit-times, the path
passes the test. NOTE: The J/FE-CF-01 has a 50 BT delay.
