The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a
single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional
graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord
maximizes the power budget of multimode 1000BASE-LX/LH links.
Note The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link
distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light
from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning
patch cord. At the output end of the patch cord, the GBIC-LX/LH is compliant with the IEEE 802.3z
standard for 1000BASE-LX.
Connecting Transceivers to a Copper Network
Caution To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded,
shielded, twisted-pair Category 5 cabling.
To connect transceivers to a copper network, follow these steps:
Step 1 Insert the network cable RJ-45 connector into the RJ-45 connector on the transceiver.
Note When connecting to a 1000BASE-T-compatible switch or repeater, use four-twisted-pair,
crossover Category 5 cabling.
Step 2 Insert the other end of the network cable into an RJ-45 connector on a 1000BASE-T-compatible target
device.
