Layer 1 Media Converter Modules
Layer 1 Media Converter Modules
for the
High-Density Media
Converter System II
convert the incoming electrical signal from one
cable type and then transmit it over another type. These media
converters bridge the gap between two different Ethernet types and
are totally transparent to network operation, having no effect on the
data being sent across the link.

Layer 1 Media Converter Modules
include the LinkLoss feature,
which notifies you of “silent failures” on copper-to-fiber links. LinkLoss
enables you to troubleshoot network problems just by looking at the
media converter’s Link LED—the link status of the fiber segment will
always be reflected by the twisted-pair segment so you’re informed
quickly of fiber problems.

Many of the twisted-pair modules feature autocrossover ports
to eliminate the worry of whether to use straight- or cross-pinned
cabling. This built-in MDI/MDI-X function auto matically determines
whether the converter has to cross over between the four pairs on
the twisted-pair port’s RJ-45 connector.

The twisted-pair modules without automatic termination
have a push button for you to choose the crossover.
10BASE-T to 10BASE-FL
10BASE-T to 10BASE-FL
These 10-Mbps media converter modules offer traditional
conversion between 10BASE-T Ethernet devices and 10BASE-FL
multimode or single-mode fiber optic devices. Use a pair of these
converters at opposite ends of the same fiber optic link to increase
your fiber reach.
100BASE-TX to 100BASE-FX
multimode or single-mode fiber optic devices. Use a pair of these
converters at opposite ends of the same fiber optic link to increase
your fiber reach.
100BASE-TX to 100BASE-FX
Order these 100-Mbps modules to convert between
100BASE-TX and 100BASE-FX devices. For converters that support
autosensing 10/100-Mbps Ethernet, see our

100BASE-TX to 100BASE-FX Single Strand
Get more mileage from your fiber cable. These modules extend
Fast Ethernet connections over a single strand of fiber cable by
compressing the transmit and receive wavelengths into one single-
mode fiber strand.
compressing the transmit and receive wavelengths into one single-
mode fiber strand.
The conversion is done with Wave-Division Multiplexing (WDM)
technology. WDM technology transmits two signals simultaneously
at different wavelengths on the same fiber. One unit transmits at
1550 nm and receives at 1310 nm. The other unit transmits at
1310 nm and receives at 1550 nm. The two wavelengths operate
independently and don’t interfere with each other. This bidirectional
traffic flow effectively converts a single fiber into a pair of “virtual
fibers,“ each driven independently at different wavelengths.
1000BASE-TX to 1000BASE-SX
at different wavelengths on the same fiber. One unit transmits at
1550 nm and receives at 1310 nm. The other unit transmits at
1310 nm and receives at 1550 nm. The two wavelengths operate
independently and don’t interfere with each other. This bidirectional
traffic flow effectively converts a single fiber into a pair of “virtual
fibers,“ each driven independently at different wavelengths.
1000BASE-TX to 1000BASE-SX
Choose these modules for Gigabit Ethernet connections of up
to 200 meters (656.2 ft.)—enough distance to support Gigabit fiber
backbone runs either within a building or between neighboring
buildings in a campus environment.
1000BASE-TX to 1000BASE-LX
backbone runs either within a building or between neighboring
buildings in a campus environment.
1000BASE-TX to 1000BASE-LX
For longer Gigabit fiber runs, choose 1000BASE-LX Gigabit
Ethernet modules, which achieve blazing Gigabit throughput at
distances of up to 40 kilometers (24.9 mi.) over single-mode fiber
cable.
1000BASE-TX to 1000BASE-SSLX
distances of up to 40 kilometers (24.9 mi.) over single-mode fiber
cable.
1000BASE-TX to 1000BASE-SSLX
Send Gigabit Ethernet at distances of up to 40 kilometers
(24.9 mi.) over a single fiber strand—truly the best performance
you can get from your fiber infrastructure.
