About 100Mbps Media Conversion Modules

100Mbps Media Conversion Modules

provide a single conversion between

100Base-TX twisted pair and 100Base-FX or SX fiber.  Each module requires one
slot in a 

Media Converter

chassis.  The following versions are available: 

LH740-TPSTM-R2

TX/FX-MM1300-ST

2 Km 

LH740-TPSCM-R2

TX/FX-MM1300-SC

2 Km

40 Km

NOTE: All modules support half- and full-duplex.

10/100 Mbps Switching Media Conversion Modules

The auto-negotiating, 10/100 switching media converter offers plug-and-play

operation,  converting 10Base-T or 100Base-TX, Half- or Full-Duplex twisted pair to
100Base-FX, Full-Duplex fiber.  This module protects against Broadcast storms, and
allows jumbo packets of up to 1916 bytes.  The following versions are available:

Configuring Media Conversion Modules

Before installing, you can configure 

10Mbps 

and 

100Mbps Modules

for

a variety of features (see diagrams/chart on page 3-4 for specific informa-
tion).  

10/100 Switching 

and

Gigabit Modules

have plug-and-play operation

and require no configuration.

This equipment has been tested and found to comply with the limits for a Class A com-

puting 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 the user will be required to correct the
interference at his own expense.

Any changes or modifications not expressly approved by the manufacturer could void the

user's authority to operate the equipment.

The use of non-shielded I/O cables may not guarantee compliance with FCC RFI limits.
This digital apparatus does not exceed the Class A limits for radio noise emission from

digital apparatus set out in the Radio Interference Regulation of the Canadian Department of
Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites

applicables aux appareils numériques de classe B prescrites dans le Règlement sur le brouil-
lage radioélectrique publié par le ministère des Communications du Canada.
