HP Mini-GBIC Transceiver Module

The HP Mini-GBIC Transceiver Module J4858C is a new network transceiver designed for wired networking environments. It provides a single 1000Base-SX SFP interface for connecting switches or routers over multi-mode optical fiber. This module suits administrators upgrading or maintaining legacy HP networking equipment that requires this specific part number.

LC Multi-mode Fiber Connectivity

The transceiver includes one LC duplex port operating at 1000Base-SX over 62.5/125 µm multi-mode fiber. This interface enables short-range gigabit links within a data centre or campus LAN. Buyers needing single-mode reach, longer distances, or a different connector type should select an alternative module.

Questions about this item

Will the LC connector or optical interface need periodic cleaning or replacement?

The LC connector should be cleaned with approved tools whenever dust or contamination is suspected; the transceiver itself has no user-serviceable parts and does not require scheduled replacement.

What is the maximum link distance supported on 62.5/125 µm multi-mode fiber at 1000 Mbps?

The module operates at 1000 Mbps over multi-mode fiber; the achievable distance depends on the fiber bandwidth and installation loss budget rather than a single fixed figure.
