1000BASE-LX Connectors311523-C Rev 00 151000BASE-LX ConnectorsThe 1000BASE-LX (gigabit) MDAs use a longwave 1300 nm, fiber optictransceiver to connect devices over single-mode (5 km/3.1 mi) or multimode(550 m/1,805 ft) fiber optic cables.The optical performance of this transceiver cannot be guaranteed when connectedto a multimode fiber plant without the use of the special offset SMF/MMF (modeconditioning) patch cord.The 1000BASE-LX MDA transceiver is designed to mechanically accommodatethe single-mode ferrules used on one end of the special offset SMF/MMF patchcord. Multimode ferrules can bind and cause damage to the transceiver.For more information about gigabit transmission over fiber optic cable and modeconditioning, refer to:Reference Note: Gigabit Ethernet Physical Layer Considerations(Part number 201540-B).The publication is available on the World Wide Web at support.baynetworks.com/library/tpubs/. At the Web site, click on Accelar under the Routing Switchesheading.Note: The transceiver must be mode conditioned externally via a special offsetSMF/MMF patch cord for 1000BASE-LX multimode applications. The offsetSMF/MMF patch cord allows the same transceiver to be used for bothmultimode and single-mode fiber. See your Nortel Networks salesrepresentative for more information about the SMF/MMF patch cord.Caution: Do not connect multimode cables directly into the 1000BASE-LXMDA transceiver. Connect a special offset SMF/MMF patch cord into thetransceiver, then connect the multimode cable into the SMF/MMF patch cord.
