Cisco SFP-10G-BX40D-I

The Cisco SFP-10G-BX40D-I is a Small Form-Factor Pluggable (SFP) transceiver module manufactured by Cisco Systems. It is designed for use in high-speed data communication networks and supports 10 Gigabit Ethernet (10GbE) connections. The "BX40D" in the model name refers to the bidirectional nature of the transceiver, where "BX" stands for bidirectional and "40D" represents the specific wavelength and power levels used for transmission and reception. The "I" at the end indicates that it is an industrial-grade module. The SFP-10G-BX40D-I operates over a single strand of single-mode fiber optic cable and uses wavelength division multiplexing (WDM) technology to transmit and receive data simultaneously on different wavelengths. It has a maximum reach of up to 40 kilometers (24.85 miles) and supports a data transfer rate of 10 Gbps. This transceiver module is commonly used in various networking devices, such as switches, routers, and network interface cards (NICs), to provide high-speed connectivity for data transmission over long distances.
