Class B Digital Device. This equipment has been tested and found to comply with
the limits for a Class B computing device pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interfer-
ence in a residential installation. However, there is no guarantee that interference
will not occur in a particular installation. This equipment generates, uses, and can
radiate radio frequency energy, and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. If this
equipment does cause harmful interference to radio or telephone reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult an experienced radio/TV technician for help.
Caution:
Changes or modifications not expressly approved by the party responsible for com-
pliance could void the user’s authority to operate the equipment.
To meet FCC requirements, shielded cables and power cords are required to con-
nect this device to a personal computer or other Class B certified device.
This digital apparatus does not exceed the Class B limits for radio noise emission
from digital apparatus set out in the Radio Interference Regulation of Industry
Canada.

The Pure Networking LGC200A, LGC201A and LGC202A are Gigabit Media
Converters. The SFP port of the LGC200A supports hot-swappable, Gigabit SFP
modules. The LGC201A has a dual SC multimode fiber connector, and the LGC202A
has a dual SC single-mode fiber connector.
Use the media converters to join a 1000BASE-TX segment to a 1000BASE-SX or
1000BASE-LX 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 transmits/receives data by 1310-nm
short-wave laser over single-mode fiber.
2.2 Features
• Complies with 802.3ab and 802.3z standards.
• Provides (1) SC/LC connector or (1) SFP module slot and (1) RJ-45 connector.
• Both TX 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 network activity.
• Uses a 9-VDC, 600 mA external power supply (included).

4.2 Installation Procedure
Use a fiber cable to connect two converters and extend a copper link or to connect
a 1000BASE-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.
• Connect one end of the CAT5 twisted pair cable to the RJ-45 jack on the convert-
er 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.
