HPE Aruba JL485A — 25G eSR SFP28, 400 m
25 GbpsSFP28 eSROM4 400 mAruba CX
The HPE Aruba Networking JL485A is an extended short-reach (eSR) 25 Gbit SFP28 transceiver for multimode fibre, reaching 200 m on OM3 and 400 m on OM4 at 850 nm over duplex LC. It covers the longer multimode runs that the standard SR cannot, such as links between rows or floors, on Aruba CX switches including the 6300, 6400, 8325 and 8360. 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 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:
The 400 m figure is for OM4; on OM3 it is 200 m. HPE states it is not supported over OM1 or OM2. Both ends should use eSR optics for the full reach. It is a single-lane 25G part — not one of the 40G/100G eSR4 modules. For short in-rack runs the JL484A SR is enough. 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.
Best For
✓ 25G links between rows or floors
✓ Longer multimode runs than SR allows
✓ Aruba CX 8325 / 8360 uplinks
✓ OM4 building backbones
✓ Avoiding a move to single-mode fibre
✓ Replacing a failed eSR module
Key Features
Four times the SR reach on OM4
400 m on OM4 versus 100 m for the standard SR, at the same 1.2 W, so longer multimode runs stay at 25G without new single-mode fibre.
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 — the figures in the table are per grade, so check what is actually in your walls before you plan a link.
Monitoring you can read
Digital diagnostics (partial, per HPE) let the switch report temperature, laser power and received light, so a dirty connector or a failing link shows up in the switch 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.

Frequently Asked Questions
Singular Expert Insight
We suggest eSR whenever a 25G multimode run is near the SR limit — patch panels and old fibre eat margin. If the link leaves the building, a single-mode optic is the better long-term answer. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status from the switch and we help you find out whether it is the optic, 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 25G on Aruba CX over OM3 up to 200 m or OM4 up to 400 m.
Skip it if
Your run is short enough for SR, your fibre is OM1/OM2, or it is single-mode.
Also consider
HPE Aruba JL484A SR for runs up to 100 m on OM4.
