Product Description

HP 3CSFP91-compatible fiber transceiver module is designed, programmed and tested to work with HP brand switches and routers. SFP Multi-Mode Fiber Optic Transceiver Module delivers dependable 1 GbE connectivity over fiber cable for 1000BASE-SX-compliant networks with a maximum distance of up to 550 meters (1804'). Maximum data-transfer rate is 1.25 Gbps. It also offers an 850nm wavelength, LC connector, power consumption less than 1 watt and Digital Diagnostics Monitoring (DDM). Use to replace defective or damaged SFP modules in HP switches and routers or to expand your network to remove segments. Tested for OEM host compatibility, it is hot-swappable in HPE routers and switches, making upgrades and replacements seamless by minimizing network disruptions.


  • 100% HPE 3CSFP91 COMPATIBLE: Works with HPE switches like 3812, 3824, 3848, 4070, and others
  • TECHNICAL SPECS: 1000BASE-SX
  • 1Gbps
  • Multi Mode (MMF)
  • LC Connector
  • 850nm
  • Digital Diagnostic Monitoring (DDM)
  • Distances up to 550m (1804ft)
  • TESTED FOR OEM HOST COMPATIBILITY: Hot-swappable in HPE routers and switches; DDM support reports the transceiver's status to most SNMP network management tools
  • LIFETIME WARRANTY: Backed by a lifetime warranty on the life of the module itself - not the life of your switch. Our modules won't void your OEM warranty and supported by our Tech Advisors 5/24
  • WORKS WITH MSA COMPLIANT SWITCHES: Also works with switch models from Ubiquiti, D-Link, Netgear, Supermicro, TP-Link and more that accept uncoded modules
