Build efficient point-to-point fiber links with a transceiver designed for 1000BASE-BX deployments. This ADDON SFP module supports bidirectional Gigabit Ethernet over a single strand of fiber, making it a practical choice when fiber availability is limited or when you want to reduce cabling complexity in access and distribution layers. The LC connector keeps integration familiar for teams working in standard optical environments, while the TAA-compliant designation supports procurement requirements in regulated or public-sector purchasing workflows. For organizations maintaining Extreme Networks infrastructure, compatibility matters as much as speed: this module is intended to slot into existing operational patterns without forcing a broader refresh. Compared with lower-cost generic optics, a purpose-matched compatible transceiver helps reduce deployment risk and keeps replacement planning predictable. It is a strong fit for teams that need a dependable spare, a clean migration path, or a controlled way to expand Gigabit fiber links without overbuying hardware.
