Aruba 40G QSFP+ LC Bidirectional 150m MMF 2-strand Transceiver

The Aruba JL308A is a QSFP+ transceiver that delivers a straightforward 40 gigabit Ethernet link over two LC multi-mode fiber strands. It supports distances up to 150 meters, giving network teams a simple way to extend high-bandwidth connections within data halls, campus cores, or aggregation layers where copper cables fall short.

This module uses a bidirectional design, so each pair of fibers carries traffic in both directions. The result is cleaner cable management, fewer fibers to terminate, and a rack that is easier to keep organized. Installation is direct: slide the transceiver into any compatible QSFP+ port and the link is ready without extra configuration.

The JL308A fits well in dense data center environments where every watt, gram, and centimeter matter. It measures roughly 1.8 x 13.2 x 0.8 cm and weighs about 45 grams, so it leaves plenty of room for airflow and neighboring hardware. Network engineers who run virtualization clusters, high-performance storage, or campus backbones will appreciate the reliable 40 Gbps throughput, the consistent wired performance, and the minimal maintenance it requires once in place.
