Small rectangular metal SFP module with LC duplex port

HPE

HPE ProCurve Gigabit-SX-LC mini-GBIC SFP module

SKU CH-FRNN-762CH

Adds a multi-mode fibre LC port for 1000Base-SX links to compatible ProCurve switches

  • Gigabit data links over multi-mode fiber using 62.5/125 µm or 50/125 µm cable
  • Compact SFP form factor fits 0.5" high slots for dense switch configurations
  • LC duplex connector enables quick, secure fiber patching in data networks
  • Weighs only 0.04 lb to minimise load on populated chassis
  • Compatible with ProCurve 5304xl, 5308xl, 5348xl, 5372xl, 2626, 2650, 2824, 2848, 6108, 9300 and 9408 series

J4858B SFP module for ProCurve switches

The HPE J4858B is a single-port SFP (mini-GBIC) transceiver designed for Gigabit Ethernet links over multi-mode fibre. It uses an LC connector and supports 1000Base-SX signalling on 62.5/125 µm and 50/125 µm cable. The compact module fits ProCurve switches that accept mini-GBIC form-factor optics.

Network teams adding short-reach fibre uplinks

This module suits administrators who need to connect compatible ProCurve switches or routing switches across multi-mode fibre runs within a building or campus. It does not support single-mode fibre, so buyers requiring longer-distance links or different wavelength optics should look at other transceiver types.

LC 1000Base-SX multi-mode interface

The decisive specification is the 1 x LC 1000Base-SX port operating on multi-mode fibre at 62.5/125 µm and 50/125 µm standards. This determines whether the module matches the cabling plant and switch port requirements for the intended Gigabit Ethernet deployment.

Questions about this item

Does the LC connector on this J4858B module need periodic cleaning or replacement?

The LC connector should be inspected and cleaned with appropriate fiber tools whenever links are installed or re-seated; the module itself has no user-replaceable parts.

What distance limit applies first when running 1000Base-SX over 62.5/125 µm multi-mode fiber?

The 62.5/125 µm cable standard supports shorter reach than 50/125 µm, so that fiber type sets the effective distance ceiling for this SFP.

How much heat does the module add to a fully populated ProCurve 5308xl chassis running continuously?

The SFP draws minimal power and its 0.5" height allows normal chassis airflow to dissipate heat without supplemental cooling.
