HPE J4859B ProCurve Gigabit-LX-LC SFP switch module

SKU CH-WENJ-H8AG4

Gigabit SFP module with LC connector for single-mode and multi-mode fiber links

  • Plug typeSFP (mini-GBIC)
  • Gigabit Ethernet over fiber with LC connector
  • Single-mode and multi-mode fiber support up to 1000Base-LX
  • Hot-swappable SFP form factor fits ProCurve switches
  • Compact module measuring 2.3" wide by .5" high and deep
  • Lightweight design at only .04 lb for dense deployments

ProCurve Gigabit-LX-LC SFP module

This HPE ProCurve J4859B mini-GBIC adds a single 1000Base-LX port to compatible switches. It targets network administrators who need long-wavelength fibre uplinks on supported ProCurve platforms.

Passive optics with no active cooling

The transceiver draws minimal power from the host switch and produces no audible noise. It operates within standard SFP thermal limits without additional airflow requirements.

Fits ProCurve SFP slots with LC duplex cabling

The module accepts 62.5/125, 50/125 and 9/125 µm fibre for both multi-mode and single-mode runs. It frees a copper port for endpoint devices while extending reach over optical fibre.

Questions about this item

How do I install the J4859B SFP module and which LC connector orientation is the common mistake?

Slide the module into an SFP slot until it clicks, then insert the LC duplex connector with the keyed tab facing the correct side — reversing the Tx and Rx fibres is the step most often done wrong.

What maintenance or replacement will the J4859B need over time?

The optical interfaces stay sealed, so the only upkeep is cleaning the LC ferrules with a lint-free wipe and isopropyl alcohol if link loss appears; the module itself has no user-replaceable parts.

What distance limit appears first on a sustained 1000Base-LX link with the J4859B?

On 62.5/125 µm multi-mode fibre the 1000Base-LX standard reaches its shortest supported distance, while 9/125 µm single-mode allows the longest reach.
