Keep long-reach fiber links simple with this 1000BASE-BX-U SFP transceiver from Axiom Memory. Designed for Gigabit Ethernet over single-mode fiber, it supports up to 20 km and uses an LC connector for clean integration into compatible network hardware. The BX-U optical profile is well suited to one-fiber, point-to-point deployments where port density and fiber efficiency matter. This module is a practical fit for enterprise access layers, campus interconnects, and provider handoffs that need stable 1 Gb optical transport without moving to a more expensive platform. The 1310 nm transmit and 1490 nm receive wavelengths align with BX-U operation, helping preserve compatibility in established fiber architectures. For teams standardizing on Cisco-compatible optics, the value is in predictable deployment and procurement flexibility. It is a focused transceiver for networks that need reach, compatibility, and dependable optical performance without excess complexity.
