The Cisco SFP-10/25G-BXD-I is a bidirectional transceiver module manufactured by Cisco. It uses the SFP28 form factor and supports 10 Gbps or 25 Gbps data transmission rates over single-mode fiber (SMF) using LC connectors.

This module operates with a wavelength of 1330 nm for transmit and 1270 nm for receive, supporting distances up to 10 km. It is designed for use in industrial temperature environments and requires operation alongside its complementary pair, such as the SFP-10/25G-BXU-I. Compatible with standard compliant networking equipment that includes an appropriate SFP28 port, it fits into front-panel ports without additional mounting hardware requirements. Power type follows conventional hot-pluggable standards used across compatible switch models from Cisco’s product line.
