Ciena XCVR-010Y31 Gigabit Ethernet SFP Transceiver

CIENA XCVR-010Y31 is a Gigabit Ethernet SFP transceiver designed for 1000BASE-LX links over single-mode fiber. The module operates at 1310 nm and can extend a 1 Gbps Ethernet link up to 10 kilometers when used with standard SMF and LC duplex fiber, making it suitable for data-center interconnects, campus networks, and metro deployments that require longer reach. It plugs into a standard SFP cage and provides a compact interface for fiber-based LANs and WANs. As a Ciena-origin part, the XCVR-010Y31 is commonly used in networks built around Ciena optical platforms and is compatible with other vendors’ 1000BASE-LX optics that use 1310 nm and SMF with LC connectors, subject to equipment interoperability. Key specifications include: data rate 1 Gbps (1000BASE-LX), wavelength 1310 nm, reach up to 10 km on single-mode fiber, and LC duplex optical interface. This makes it a direct option for replacing aging LX optics or extending fiber links in environments where 1310 nm SMF optics are specified, without requiring additional fiber or altering existing copper segments.
