About Media Converters
The modular
Media Converter Series
includes
modules that convert copper to single-mode,
multi-mode or single-strand fiber at Ethernet, Fast
Ethernet and Gigabit Ethernet speeds, and mod-
ules that convert copper to thin coax at Ethernet
speeds. Modules install in a variety of chassis.
Media Converter Chassis
Media Converter chassis
provide power to the media conversion modules.
•
1-PPort
(LE7401A-R2) chassis include one media conversion module slot.
•
4-PPort
(LE7404A) chassis include four media conversion module slots.
•
8-PPort
(LE7408A) chassis is a 1U high rackmountable that includes eight
media conversion module slots.
The 1, 4 and 8 slot chassis include a fixed 100/240 VAC power supply.
•
12-PPort
chassis is rackmountable and includes 12 media conversion module
slots and either a 100/240 VAC (LE74012A) or -48 VDC (LE74012A-DC)
power supply. The 12-Slot chassis is 1U high and has the power on the rear
of the chassis with media conversion module slots on the front.
10Mbps Media Conversion Modules
10Mbps Media Conversion Modules
provide a single conversion between
10Base-T twisted pair and either 10Base-FL fiber or 10Base-2 coax. Each module
requires one slot in a
Media Converter
chassis. The following versions are available:
