System compatibilitySFP-25G-SR SFP28 module works with Extreme Networks switches with SFP28/QSFP28 ports: X690,X590,X870 series. It is used for short-range 25G server leaf uplink inside data center.

FunctionSFP-25G-SR converts 25G electrical signal to 850nm multimode optical signal for short-distance transmission. It supports real-time DDM monitoring of transmit power,receive power,module temperature and supply voltage. Recommended to enable RS-FEC for stable 25G link performance. Widely used for rack level server to leaf switch 25G connections.

InstallationHot-plug SFP28 module into SFP28 port of switch. Connect duplex LC multimode fiber patch cord. Verify module identification,DDM readings and optical link status before commissioning.

InterfaceSFP28 gold finger edge,duplex LC optical port,DDM digital diagnostic,status indicator for Extreme Networks SFP-25G-SR.

FeatureOriginal Extreme Networks SFP28 25GBASE-SR transceiver,short reach multimode transmission,850nm VCSEL laser,DDM real-time optical monitoring,hot pluggable,Class1 eye-safe laser,supports RS-FEC. This spare supports data center leaf switch short-range 25G server access deployment.

DiagnosticModule not detected: check SFP28 slot contact,clean gold finger and verify switch firmware compatibility. No optical link: inspect LC fiber endface cleanliness,check multimode fiber type and port admin status. Low optical power alarm: dirty fiber connectors or damaged multimode cable. Over-temperature alarm: check ventilation and module seating.

Product BriefSFP-25G-SR is Extreme Networks SFP28 25GBASE-SR multimode optical transceiver,classic spare part for short-range 25G server uplink in data center leaf networks.
