The StarTech.com JD119BST is an HP JD119B-compatible 1000BASE-LX SFP transceiver for network teams connecting compatible equipment over single-mode fiber, with a 1310 nm wavelength, LC duplex connector, and reach up to 10 km.

Recommended For

  • Network administrators replacing a failed or missing HP JD119B optic in compatible HPE/HP equipment who need a 1GbE, 1000BASE-LX fiber link. Confirm the exact switch supports the module before deployment.
  • IT teams linking switches or network closets over installed single-mode fiber when the connection needs 1GbE and the link is within the module’s stated 10 km reach.
  • Teams extending a 1GbE network between buildings or other separated areas that already have compatible single-mode fiber and duplex LC connections at both ends.
  • Network technicians who want Digital Diagnostics Monitoring on a compatible link to check transceiver status during setup or troubleshooting.

Real-World Use Scenarios

  • Connect two HP-compatible switches across existing single-mode fiber between campus buildings; the module provides a Gigabit Ethernet link without replacing the switches, provided both ends and the fiber path are compatible.
  • Replace a failed JD119B-compatible optic in an existing switch; if the switch supports the module, this can restore the fiber link without changing the network’s switch hardware.
  • Link a remote wiring closet or floor switch back to a central switch over a single-mode fiber run; the result is a 1GbE uplink for network traffic where a copper run is unsuitable or too long.
  • Bring a nearby outbuilding or separate office onto the main LAN using a fiber-connected switch at each location; community discussions describe 1G LX optics as one option when the fiber type and switch ports match.
  • Check optical diagnostics during link troubleshooting or maintenance; the module supports DDM, although the host switch must also support displaying those readings.
