System compatibility40GB-LR4-QSFP is Extreme Networks original 40G single-mode QSFP+ transceiver. Compatible with Extreme X620, X650, X670V, X460-G2, VSP series switches with QSFP+ slots. It is used for long-distance 40G interconnection between data center racks and campus core network. Widely used for long fiber link spare replacement.
Function40GB-LR4-QSFP is a 4-channel CWDM4 optical transceiver. It multiplexes four 10G lanes into one 40G optical signal for transmission over single-mode fiber. It supports DDM to monitor transmit optical power, receive power, module temperature and supply voltage. It triggers alarms for optical signal loss, over-temperature or module fault. Used to replace faulty 40G LR4 optical modules for long-distance 40G fiber links.
InstallationPower off chassis before installation. Insert 40GB-LR4-QSFP into the switch QSFP+ slot. Connect duplex LC single-mode fiber to the module port. Verify module recognition on ExtremeXOS/VOSS, check optical power and port link status before putting into production.
InterfaceQSFP+ edge connector, duplex LC receptacle, DDM digital diagnostic interface, pull tab for easy removal for Extreme Networks 40GB-LR4-QSFP.
FeatureOriginal Extreme Networks 40G LR4 QSFP+ transceiver, hot-pluggable, CWDM4 four-wavelength design, 10km single-mode transmission, DDM real-time monitoring, low power consumption, compliant with IEEE 802.3ba and QSFP+ MSA standard. This spare supports data center and campus long-distance 40G fiber interconnection.
DiagnosticModule undetected: check insertion, slot status and switch firmware compatibility. Port link down: verify LC single-mode fiber connection, optical power and port admin status. Link flapping: inspect fiber quality, connector cleaning and DDM readings.
Product Brief40GB-LR4-QSFP is Extreme Networks QSFP+ 40GBASE-LR4 single-mode optical transceiver with duplex LC interface, supporting 10km transmission over OS2 single-mode fiber, classic spare part for data center and campus long-distance 40G network overhaul.
