BlueOptics J4858D-BO — HPE Aruba J4858D-Compatible 1G SX SFP
1 Gbps1000BASE-SXHPE Aruba codedUp to 550 m
The BlueOptics J4858D-BO is a Gigabit SFP transceiver for multimode fibre, coded to identify as an HPE Aruba J4858D: 1000BASE-SX at 850 nm over an LC duplex connection, up to 550 m, with digital diagnostics. It is the BlueOptics BO05C856S5D module, a lower-cost way to add or replace SX optics in HPE Aruba and ProCurve switches that check the optic code. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry multimode fibre, and the module plus a short LC 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 HPE Aruba J4858D; switches of other brands may reject that code — BlueOptics sells the same optic with other codings. It needs multimode fibre and an 850 nm SX module at the far end; for single-mode runs the J4859D (1000BASE-LX, 10 km) is the matching part. It is a 1G optic and will not come up in a 10G-only port. 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 switch model and the cable run and we check it before you order.

Key Features
Coded for HPE Aruba
Programmed as an HPE Aruba J4858D, so Aruba switches that check optics accept it as a supported module.
Multimode fibre, short reach
Built for the short runs inside a building or data room over multimode fibre. Reach depends on the fibre grade — older 62.5 µm OM1 fibre reaches less than 50 µm OM2 or better, so check what is actually in your walls before you plan a link.
Monitoring you can read
Digital diagnostics (DDM (SFF-8472)) 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 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 to remove it.

Buyer’s Guide
Buy it if
You need a 1G multimode link up to 550 m on an HPE Aruba switch that expects J4858D optics.
Skip it if
Your switch is another brand, your fibre is single-mode, or the port is 10G-only.
