ProLabs J4858D-C — HP J4858D Compatible 1G SX SFP
1 Gbps1000BASE-SX850 nm · LCHP J4858D coded
The ProLabs J4858D-C is a Gigabit SFP transceiver for multimode fibre, coded as the HP J4858D: 1000BASE-SX at 850 nm over an LC duplex connection, up to 550 m, with digital optical monitoring (DOM). ProLabs, part of Amphenol, programs, serialises and traffic-tests each module, and the part is TAA compliant. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry OM3 or OM4 fibre, and the module plus a short patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.
Compatibility — check before buying:
It is coded as HP J4858D, the Gigabit SX optic of HP / Aruba switches; send us your switch model before ordering. It needs multimode fibre and an SX module at the far end, and it is 1G only. ProLabs also sells J4858D-C-5PK (5-pack) and J4858C-C (coded for older J4858C hosts) — check which one your order needs. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your device model and the cable run and we check it before you order.
Best For
✓ HP / Aruba switches using J4858D optics
✓ Short fibre runs inside one building
✓ Server room and riser links
✓ Links that need DOM readings
✓ Projects that require TAA compliance
✓ Replacing a failed J4858D
Key Features
Coded and tested for HP
Programmed as the HP J4858D and traffic-tested by ProLabs, so the switch identifies it as a supported SX module.
Multimode fibre, short reach
Built for the short runs inside a building or data room over OM-grade multimode fibre. Reach depends on the fibre grade — check what is actually in your walls before you plan a link.
Monitoring you can read
Digital diagnostics (DOM) let the host report temperature, laser power and received light, so a dirty connector or a failing link shows up before users call.
Hot-swappable
Modules and cables plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch or pull tab to remove it.

Frequently Asked Questions
Singular Expert Insight
We offer the J4858D-C for HP / Aruba switches that need a Gigabit multimode optic with DOM and a long manufacturer warranty. If you order several, ask us about the 5-pack; for single-mode links between buildings, an LX module coded for the same switch is the right choice. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status and we help you find out whether it is the module, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You need a 1G multimode link up to 550 m on an HP / Aruba switch that takes J4858D optics.
Skip it if
Your switch is Cisco or another brand, your fibre is single-mode, or the port is 10G-only.
