Aruba 40G QSFP+ LC BiDi 150m MMF XCVR

The Aruba X141 is a 40G QSFP+ LC BiDi optical transceiver for connecting compatible Aruba 8400X switches over multimode fiber at distances up to 150 meters, making it suitable for data-center and enterprise network links that need 40GbE connectivity.

Recommended For

• Aruba network administrators adding 40GbE links between supported switches with QSFP+ ports; check the switch model and minimum software version before deployment.
• Data-center or campus teams connecting network equipment over existing duplex LC multimode fiber, when the installed fiber is OM3 or OM4 and the link is within the supported distance.
• Network teams needing a 40GbE optical link over two-strand LC cabling rather than an MPO-connector fiber path.

Real-World Use Scenarios

• Connecting two compatible Aruba switches across a short data-center or building fiber run: the link can provide a 40GbE inter-switch connection over supported multimode fiber, within the optic’s distance limits.
• Upgrading a switch uplink where duplex LC multimode cabling is already installed: this BiDi optic can carry a 40G link over a two-strand LC fiber connection, avoiding the need to replace it with an MPO-based run when the existing fiber is suitable.
• Linking nearby racks or network rooms over OM3 or OM4 fiber: it can serve as a short-reach 40GbE connection, with Aruba listing up to 100 m on OM3 and 150 m on OM4; OM1 and OM2 are not supported.
• Replacing a lower-speed connection on a supported Aruba switch with a 40GbE link: it can increase the capacity of a switch-to-switch or aggregation connection, provided both switch ports, software, optics, and fiber are compatible.
• Planning a 40G link between different switch brands: check each device’s supported optics and confirm the BiDi modules’ optical characteristics match before deployment, since community discussions note that compatibility should not be assumed across vendors.
