Figure 12 Removing a GBIC with spring tabs
•If the GBIC has an extractor handle (Figure 9 on page 23), grasp the handle and pull firmly to remove the GBIC from the MDA’s Host port.
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. With the offset SMF/MMF patch cord, you can use the same transceiver for both multimode and single-mode fiber. For more information about the SMF/ MMF patch cord, see your Nortel Networks sales representative.
The 1000BASE-LX transceiver is designed to mechanically accommodate 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.
