General
The 1000BASE-T to 1000BASE-SX/LX media converter series provides 1000Mbps Gigabit Ethernet copper-to-fiber media conversion, allowing for 1000Base-T-1000Base-X over
multimode or optional single-mode fiber optical media.
Features
• Gigabit copper to fiber conversion: 1000Base-T-to1000Base-SX/LX over multimode or single-mode fiber
• SFP design : For flexibility, a n SFP (Mini-GBIC) connector
is provided for the fiber port to accommodate any type of
SFP fiber transceiver when needed.
• Support full wire speed copper to fiber conversion
• Auto MDI/MDI-X detection function on the copper port
• Auto-negotiation support
• Plug and play : no configuration settings is required
• Link Fault Pass Through : this function allows link fault
status passes through between copper link and fiber link
transparently.
• Far End Fault function on fiber port
• Transparent conversion to any type of packet frame
• No packet length limitation
• Diversified mounting support : desktop mounting, wall
mounting, optional Din-Rail support
• Center chassis installation : support installation in an center chassis rack with benefits of central software management and redundant power backup.
• Support wide range of fiber options : multimode f iber, single
mode fiber (short reach up to long reach), Bi-directional
single fiber, and CWDM optical
• Low power consumption

Desktop Mounting
The device can be mounted on a desktop or shelf. Make sure
that there is proper heat dissipation from and adequate ventilation around the device. Do not place heavy objects on the
device.
Wall Mounting
The device provides a mounting hole on the bottom case as
shown in the figure. Use the hole for a wall mounting.
Applying Power
Before you begin the installation, check the AC voltage of your
area. The AC power adapter which is used to supply the DC
power for the device should have the AC voltage matching
the commercial power voltage in your area. Use one of the
following rated AC-DC power adapters for your installation.
AC120V/60Hz DC7.5V/1A AC230V/50Hz DC7.5V/1A
AC100V/50-60Hz DC7.5V/1A AC100V/50-60Hz DC5V/1A
AC240V/50Hz DC7.5V/1A
T ypical Application
Use two media converters connected with an appropriate fiber cable to extend the connection distance between two Gigabit copper devices as shown below:
Connecting to a Fiber Gigabit Ethernet Port
The converter can also connect to a remote fiber Gigabit Ethernet port over a fiber cable. It extends the connection distance between a copper port and a fiber port as shown below:

DIN-Rail Mounting
For a Din-Rail chassis, the media converter can support mounting on a Din-Rail. An optional Din-Rail bracket, KC-3DR can
be purchased separately. Consult your dealer for details. The
following figures show an example after bracket installation:
Center Chassis Installation
The media converter can also be installed in KC-1300 center
chassis. The center chassis provides the power supply to the
converter also with optional power redundancy. Up to 16 units
can be installed in one chassis. Unscrew and remove the cover
of the center connector before inserting the converter into the
chassis. Refer to the operation manual of center chassis KC1300 for more information.
