JL078A - Aruba 3810M 1QSFP+ 40GbE Module

HPE Aruba JL078A — Aruba 3810M 1QSFP+ 40GbE Uplink Module

What it is

JL078A is an HPE Aruba 3810M Series uplink module that adds a single 40 GbE QSFP+ port to compatible 3810M modular switches.
This module provides high-capacity uplink connectivity for aggregation and backbone links where increased bandwidth is required.

Why buyers pick JL078A (plain English)

High-speed uplink performance
A 40 GbE QSFP+ port delivers a big jump in throughput for uplinks to distribution, core, or data center aggregation fabric.

Modular flexibility
Installs into the expansion/uplink slot of Aruba 3810M switches so you can tailor uplink capacity without replacing the whole chassis.

Fiber or DAC options
Supports a range of QSFP+ optics and DACs, giving flexibility for short-reach copper or long-reach fiber connections.

Enterprise interoperability
Works within Aruba OS-CX/AOS environments and mixes with other 3810M modules for flexible stacking and uplink designs.

Optimized for growing networks
Ideal for environments scaling to high-bandwidth backbones or converged traffic patterns.

Use case
High-capacity uplinks, backbone links, campus distribution.

Where it fits (and when to choose something else)

Perfect for:

• 3810M switches needing higher uplink bandwidth

• Campus aggregation and distribution layers

• Uplink links to data center spine/cores

• Environments with mixed high-speed traffic profiles

Choose something else if:

• You need multiple 40 GbE ports → higher-density uplink modules

• You want built-in QSFP+ on the chassis → fixed-port platforms

• You need 100 GbE → Aruba 8400 modular platforms with appropriate line cards

TL;DR

JL078A is Aruba’s 3810M 40 GbE QSFP+ uplink module:
a modular expansion card that delivers high-speed uplink connectivity for aggregation and backbone networking in enterprise deployments.
