JL486A - Aruba 25G SFP28 LC LR 10km SMF Transceiver

Aruba JL486A — 25G SFP28 LC LR 10km SMF Transceiver

What it is

JL486A is an Aruba/HPE 25GbE SFP28 optical transceiver.
It’s the standard 25GBASE-LR (long-reach) module for single-mode fiber, used to light up 25G SFP28 ports on Aruba CX switches and compatible HPE platforms. Think “default 25G optic for longer in-building or campus runs.”

Why buyers pick JL486A (plain English)

• 25G over long fiber runs
  When SR multimode won’t reach far enough, LR on single-mode does.

• Campus / building backbone friendly
  Perfect for closet-to-closet, core-to-aggregation, or remote-IDF links.

• First-party Aruba/HPE coding
  Clean compatibility and support on Aruba CX gear.

• Optical health visibility
  Digital diagnostics let you read Tx/Rx power levels for troubleshooting.

Use case

• 25G switch-to-switch or switch-to-server links over single-mode fiber at campus / metro-building distances

Where it fits (and when to choose something else)

Perfect for:

• Campus backbones needing 25G beyond 100m

• Aggregation/core uplinks between buildings or distant closets

• Any SMF run where you want 25Gb bandwidth without QSFP

Choose something else if:

• Your run is short and on multimode → 25GBASE-SR (like JL484A) is cheaper

• You need 40G/100G uplinks → step up to QSFP+/QSFP28 optics

TL;DR

JL486A is the Aruba 25G SFP28 LR single-mode optic:
1310nm, duplex-LC, ~10km reach — the standard long-reach 25Gb transceiver for Aruba CX networks.
