What form factor does the HPE Aruba JL308A transceiver use?

The HPE Aruba JL308A is described as a 40G QSFP+ LC bidirectional transceiver. This indicates it uses the QSFP+ form factor designed for 40G optical ports on compatible switches. Procurement teams should ensure that target network devices provide QSFP+ slots to take full advantage of this 40G optical module.

Which type of fiber does the JL308A transceiver support?

The JL308A is specified as a 40G QSFP+ LC bidirectional 150 m MMF 2 strand transceiver. The MMF designation indicates multimode fiber is required for its optical links. This makes it appropriate for environments with an existing multimode fiber cabling plant terminated in LC connectors.

What is the maximum supported distance for the JL308A on multimode fiber?

: "According to the product description, the JL308A supports distances up to 150 meters over multimode fiber. This reach is suitable for short to medium distance connections, such as between racks, rows, or wiring closets within the same building or data hall in enterprise deployments.

How many fiber strands are needed per link with the JL308A?

The JL308A is defined as a 2 strand transceiver, meaning each 40G connection uses two strands of multimode fiber. This aligns with an LC bidirectional design where one LC duplex connection provides the necessary optical paths. It enables efficient use of existing duplex fiber infrastructure for 40G links.

Is the JL308A suitable for enterprise and data center applications?

Yes, the JL308A is described as an HPE Aruba Networking 40G QSFP+ LC bidirectional 150 m MMF 2 strand Transceiver at the enterprise product level. Its 40G QSFP+ form factor, multimode fiber support, and 150 meter reach make it appropriate for typical enterprise and data center aggregation or core connections.
