Aruba JL308A

Overview

The Aruba JL308A is a 40G QSFP+ transceiver designed to deliver high-speed Ethernet connections over two strands of multi-mode fiber. It supports data rates up to 40 Gbps and distances up to 150 meters, making it an effective solution for extending network links in data centers, campus cores, and aggregation layers where copper cabling is insufficient. Its bidirectional design allows each fiber pair to carry traffic both ways, simplifying cable management and reducing fiber count.

Key features

• Supports 40 Gbps data transmission using the Ethernet 40GBase-X standard for high-bandwidth applications
• Bidirectional two-strand LC fiber connection reduces the number of fibers needed, improving cable organization
• Compact and lightweight form factor minimizes space usage and allows better airflow in dense rack environments
• Plug-and-play installation with any compatible QSFP+ port, requiring no additional configuration
• Reliable wired connectivity suited for virtualization clusters, high-performance storage, and campus backbone networks

Key specs

• Data rate: 40 Gbps
• Fiber type: Multi-mode fiber (MMF)
• Maximum distance: 150 meters
• Connector type: LC duplex
• Dimensions: 1.8 cm x 13.2 cm x 0.8 cm
• Weight: approximately 45 grams

Connectivity and compatibility

This transceiver is compatible with any QSFP+ port supporting the 40GBase-X standard, allowing seamless integration into existing network switches and equipment. The use of LC connectors ensures compatibility with standard multi-mode fiber cabling commonly deployed in data centers and enterprise networks.

Ideal uses and environments

The JL308A is well suited for data center environments where space and power efficiency are critical. It works effectively in campus networks and aggregation layers that require stable, high-speed fiber links. Network engineers managing virtualization, storage, or backbone infrastructure will find this transceiver a practical choice for maintaining consistent 40 Gbps connectivity with minimal maintenance.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
