The SFP-25G-BX-D-40-I is a 25 Gigabit Ethernet (25GbE) Bi-Directional (BiDi) SFP28 transceiver designed for single-mode fiber (SMF) communication. It supports transmission distances of up to 40 kilometers over a single fiber strand, using different wavelengths for transmit and receive functions. The “BX-D” indicates the receive wavelength, complementing the “BX-U” transceiver. The “I” suffix usually denotes an industrial temperature range, making it suitable for deployment in harsh environmental conditions. This type of transceiver is utilized in high-speed data center and telecommunications applications where efficient fiber usage is crucial.
