1000BASE-L X segment on your network, or use them in pairs to extend the
328-feet (100-m) distance limitation of copper-based Ethernet.
Three converter models are available:
• LGC200A: This SFP module media converter transmits/receives data based on the
SFP module that is installed.
• LGC201A: This fiber SC media converter transmits/receives data by 850-nm
short-wave laser over multimode fiber.
• LGC202A: This fiber SC media converter transmit s/ receives data by 1310-nm
short-wave laser over single-mode fiber.
2.2 Features
• Complies with 802.3ab and 802.3z standards.
• Provid es (1) SC /LC connector or (1) SFP module slot and (1) RJ-45 connec tor.
• Both T X and FX ports work at 1000 Mbps in full-duplex mode.
• Supports Auto MDI /MDI-X for the TX port.
• Extends fiber distance up to 0.55 kilometers for multimode fiber and 15 kilometers
for single-mode fiber.
• Easy-to-view LED indicators provide status to easily monitor net work activity.

4.2 Installation Procedure
Use a fiber cable to connect two converters and extend a copper link or to connect
a 1000 BASE- FX segment to a 1000BASE-X segment on your network.
1. Connect a converter to a 1000BASE-TX device (hub or switch ).
• Make sure that the CAT5 twisted pair cable between the 1000BASE-TX device
and the converter is less than 328 feet (100 ) meters long.
• Connec t one end of the CAT5 twisted pair cable to the RJ -45 jack on the conver ter and the other end of the cable to the RJ-45 jack on the 1000BASE-TX device.
2. Connect two converters or a converter and a 1000BASE- FX device.
• Use an SC fiber cable to connect the two converters’ SC connector or the SC
connector of a converter and a 1000BASE-FX device.
3. Turn on the power.
4.3 Install the Media Converter into the LHC200A-RACK
1. Take out the two screws located on the top of the chassis and use them to install
the retainer as shown in Figure 4-5.

5.1 LEDs on the Media Converters
The converters have real-time LED indicators that can provide real-time status
reports. Just look at the LEDs to deterimine the link status. Figure 5-1 shows the
LEDs, and Table 5-1 describes their functions.

6. Troubleshooting
6.1 Contacting Black Box
If you determine that your Pure Networking Gigabit Media Converter is
malfunctioning, do not attempt to alter or repair the unit. It contains no
user-serviceable parts. Contact Black Box Technical Support at 724-746-5500
or info@blackbox.com.
Before you do, make a record of the history of the problem. We will be able to
provide more ef ficient and accurate assistance if you have a complete description,
including:
• the nature and duration of the problem.
• when the problem occurs.
• the components involved in the problem.
• any particular application that, when used, appears to create the problem or make
it wor se.
6.2 Shipping and Packaging
If you need to transport or ship your Pure Networking Gigabit Media Converter:
• Package it carefully. We re commend that you use the original container.
• If you are returning the unit, make sure you include everything you received with
it. Before you ship for return or repair, contact Black Box to get a Return
Authorization (RA) number.
