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 pushbutton for you to choose the crossover.
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
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 Layer 2
Media Converter Modules for the High-Density Media
Converter System II (
pages 9–10
).
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.
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
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
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
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.
