FEATURES
• 10-/100-Mbps autosensing on the
copper port.
• Choose multimode or single-mode,
ST or SC connectors.
• Internal power supply is included.
• Only 1U high—fits nearly anywhere!
Use a pair of media converters to connect two multimode
fiber optic network segments via single-mode fiber.
OVERVIEW
Connect 10BASE-T or 100BASE-TX devices to your fiber-
based cabling infrastructure with a BLACK BOX
®
10-/100-Mbps
Autosensing Media Converters. You can use these versatile
media converters to convert 10BASE-T to fiber now and
100BASE-TX to 100BASE-SX or 100BASE-FX fiber later.
Reduce fiber connectivity costs by using these 1U-high
media converters as the link between your fiber network
and your copper-based switches. Not only are they ideal
for future-proofing your fiber-to-desktop applications,
they also make upgrading to 100-Mbps workstations
affordable. All you have to do is change the network
interface card. It’s that simple!
The converters are available in multimode and single-
mode versions with ST or SC connectors. Choose multimode
for shorter distances (up to 984.3 ft. [300 meters]) and short-
wave transmissions over 850-nm fiber in accordance with the
100BASE-SX standard. Or choose the multimode models that
support 1300-nm fiber at distances up to 1.2 miles (2 km).
Single-mode versions support distances up to 49.7 miles
(80 km) and transmit over 1300- or 1550-nm fiber. The
1300-nm multimode versions and the single-mode versions
are 100BASE-FX compliant.
Power is supplied through an internal 100-/240-VAC power
supply, eliminating the need for unreliable, bulky external
AC/DC transformers.
Link-Fault Detection helps you easily locate faults. When
faults occur, the front-panel LEDs light and show you exactly
where the cable fault is located. The converters also feature a
button by the twisted-pair port for selecting a crossover
workstation connection or a pass-through
repeater/hub/switch connection.
The converter has three modes of operation:
• PNP/Transparent. Autonegotiating, in which the
converter automatically configures for 10 or 100 Mbps
and half- or full duplex. This is the default operation
mode.
• Force-10. The unit acts as a regular 10BASE-T↔
10BASE-FL converter.
• Force-100. The unit functions as a 100BASE-TX↔
100BASE-SX (LMC7001A-R4–LMC7002A-R4), or
100BASE-TX↔100BASE-FX converter (LMC7005A–
LM7006A, LMC7003A-R4–LMC7004A-R4, LMC7007A–
LM7009A).
TYPICAL APPLICATIONS
These media converters are ideally suited for small
companies and remote campuses requiring minimal fiber
connectivity.
The typical user has a 10-Mbps fiber network, plans to
upgrade to 100 Mbps in the future, and doesn’t want to
buy new media converters for the upgrade.
