Move 10 GbE traffic farther without changing the fiber plant. This Aruba BiDi transceiver is built for long-reach single-mode deployments, supporting up to 40 km over an LC connection using paired 1330/1270 nm wavelengths. That makes it a strong fit for metro extensions, campus interconnects, and remote facility links where distance and fiber availability drive the design. BiDi optics reduce cabling complexity by sending and receiving over a single strand of fiber, which can help preserve infrastructure capacity in dense or expensive routes. For teams planning long-haul Ethernet links, that means fewer fibers to manage and a cleaner path to extending network services between buildings, sites, or aggregation points. This module is aimed at environments that need dependable optical reach and vendor-aligned compatibility for Aruba switching platforms. It is the kind of component that earns its place in the bill of materials by solving a specific problem: carrying 10 GbE farther, with less fiber, and without overbuilding the link.
