Build long-reach 10 Gb links without adding unnecessary fiber complexity. The Extreme Networks 10GB-BX10-D SFP+ transceiver supports single-fiber operation over single-mode fiber, making it a practical fit for enterprise networks that need to conserve cabling while maintaining predictable transport. Its 10 km reach gives you room for campus interconnects, building-to-building runs, and distribution links that exceed short-reach optics. The SFP+ form factor keeps the module compact for high-density switch environments, while the single-fiber design helps simplify plant planning where available strands are limited or already allocated. For infrastructure teams standardizing on Extreme Networks hardware, this optic provides a straightforward way to extend 10 Gb Ethernet across compatible platforms. It is a strong choice when the network design calls for long-distance connectivity, efficient fiber use, and a module built for enterprise switching economics rather than commodity short-haul links.
