The SFP-10G-BXU-80 is a 10 Gigabit Ethernet (10GbE) Bi-Directional (BiDi) SFP+ transceiver. It’s designed for single-strand single-mode fiber (SMF) communication, typically reaching distances up to 80 kilometers. This module uses a pair of wavelengths (e.g., 1270nm and 1330nm) to transmit and receive data over a single fiber, reducing the number of fibers required. The “BXU” signifies the transmit wavelength, and “80” indicates the maximum distance in kilometers. This type of transceiver is commonly used in long-haul telecommunications and data center interconnects.
