FAQ's
What fiber type does the SFP-1G-BX43-D-40-I-AO support? This transceiver supports single-mode fiber (SMF) for long-distance data transmission up to 40 kilometers. What does 1000Base-BX mean in this context? 1000Base-BX is a gigabit Ethernet standard using bidirectional communication over a single fiber strand, enabling data transmission in both directions. Is this module compatible with all SFP slots? The module fits standard SFP ports but compatibility depends on the host device supporting 1000Base-BX and AddOn modules. Can this SFP module operate on multimode fiber? No, it is designed specifically for single-mode fiber and will not function properly on multimode fiber. How is the 40 km distance specification determined? The 40 km maximum distance is based on single-mode fiber characteristics and standard optical power budgets for 1000Base-BX communication. Does this SFP require special configuration after installation? The module is typically plug-and-play, but network devices may require settings adjustments to recognize bidirectional operation and correct wavelength.
