Cisco SFP-10G-ER Compatible SFP+ 10GBASE-ER 1550nm 40km DOM Duplex LC/UPC SMF Optical Transceiver Module

Cisco SFP‑10G‑ER SFP+ transceiver is a high‑performance, long‑reach optical module designed for 10 Gigabit Ethernet connectivity over single‑mode fibre (SMF). Operating at a nominal wavelength of 1550 nm and capable of reaching up to 40 km (on G.652 SMF), this module is ideal for enterprise, data‑centre or service‑provider applications where high‑density, high‑speed fibre links are needed. With a standard LC duplex connector, hot‑swappable SFP+ form‑factor and digital optical monitoring (DOM) support, it offers reliable performance and future‑proof infrastructure scalability.

Product Features

Hot‑Swappable SFP+ Form Factor

Designed for plug‑and‑play installation, the module fits into industry‑standard SFP+ ports, enabling easy upgrades or replacements without powering down the network device.

10 Gbps Long‑Reach Single‑Mode Fibre Support

Supports 10 Gigabit Ethernet (10GBASE‑ER) over standard single‑mode fibre up to approximately 40 km on G.652 SMF.

Wavelength 1550 nm with LC Duplex Connector

Operates at 1550 nm wavelength and uses a duplex LC/UPC optical interface — compatible with standard SMF optics infrastructure.

Digital Optical Monitoring (DOM) Support

Provides real‑time diagnostics of optical parameters (such as temperature, TX/RX power, voltage) through the module’s interface, helping administrators monitor link health and performance.

Broad Compatibility with Cisco Platforms

Certified for use with a wide range of Cisco switches and routers featuring SFP+ ports, enabling consistent optical deployment across your network.

Deployment & Usage Tips

• Ensure that the host device (switch/router) supports the SFP‑10G‑ER module or similar optics — check the compatibility matrix for your platform.
• Use quality single‑mode fibre (G.652) cabling for best results when targeting near the 40 km reach.
• Clean fibre connectors and dust caps before installation to maintain optical performance and longevity.
• Monitor module diagnostics (DOM) to pre‑emptively detect link degradation or impairments.
• If your link needs exceed 40 km, consider longer‑reach modules (e.g., 10GBASE‑ZR) or repeaters/optical amplifiers.
