1000BASE-LX Multimode Applications

For 1000BASE-LX multimode applications, the longwave gigabit transceivers
must be mode conditioned externally via a special offset SMF/MMF patch cord.
The offset SMF/MMF patch cord allows the same transceiver to be used for both
multimode and single-mode fiber. See your Bay Networks sales representative for
more information about the SMF/MMF patch cord.
The 1000BASE-LX transceiver is designed to mechanically accomodate the
single-mode ferrules used on one end of the special offset SMF/MMF patch cord.
Multimode ferrules must not be used because they can bind and cause damage to
the transceiver. Do not connect multimode cables directly into the 1000BASE-LX
MDA transceiver. Instead, connect a special offset SMF/MMF patch cord into the
transceiver, and then connect the multimode cable into the SMF/MMF patch cord.
For more information about gigabit transmission over fiber optic cable and mode
conditioning, refer to the following publication:

Description
On: The corresponding Phy port is active.
Off: The corresponding Phy port is in backup mode or there is no
connection to this port.
Port activity LEDs (green):
Blinking: Indicates network activity level for the corresponding port. A high
level of network activity can cause LEDs to appear to be on continuously.
