SFP+ Fiber Optic Transceiver Cisco SFP-10G-LR-S Refurbished, 10 Gbps, 1310 nm

Cisco SFP-10G-LR-S, refurbished, is a pluggable SFP+ optical transceiver designed for 10 Gigabit Ethernet links over single-mode fiber. It supports a nominal wavelength of 1310 nm and fits SFP+ ports to provide a compact, hot‑pluggable interface for long-reach optical connections in data centers, campus networks, metropolitan access rings and storage networks.

Advantages

The module offers compact SFP+ form factor compatibility, a 10 Gbit/s line rate and support for single-mode fiber at 1310 nm, enabling long-reach optical links. As a refurbished spare, it provides a cost-effective option for expanding or maintaining existing Cisco ONS and other compatible multiservice platforms while preserving interoperability with SFP+ ports and MSA-compliant systems.

Suitable for

• 10 Gigabit Ethernet uplinks in data centers and server racks
• Long-reach single-mode fiber links between campus buildings or POPs
• Metropolitan access and ring network segments requiring SFP+ ports
• Storage area network connections using 10 Gbit/s optics

When it may not be suitable

This refurbished SFP+ transceiver is not suitable where new‑unit warranty, certified lifecycle tracking, or vendor‑specific new‑product support is required. It also is not appropriate for multimode fiber runs or for applications that require different wavelengths or form factors (for example XFP, CFP or CXP).

Key specifications

• Form factor: SFP+
• Data rate: 10 000 Mbit/s (10 Gbit/s)
• Optical type: Single‑mode fiber
• Wavelength: 1310 nm (nominal)
• Dimensions: approx. 13.4 mm (W) × 56.5 mm (D) × 8.5 mm (H)
• Quantity included: 1 unit
• Compliance: MSA‑compliant SFP+ interface

How to use

Insert the SFP+ transceiver into a compatible SFP+ slot on the network device while the device is powered on or as recommended by the equipment vendor for hot‑plug operations. Connect single‑mode fiber patch cables to the transceiver’s optical interface, observing correct Tx/Rx orientation and using LC connectors as required. Verify link status and configure the network interface on the switch or router according to your network settings.

What to consider before purchase

• Confirm your switch or router supports SFP+ optics and accepts refurbished or third‑party transceivers.
• Ensure you need 10 Gbit/s single‑mode operation at 1310 nm rather than multimode or different wavelength optics.
• Check physical dimensions and compatibility with caged or uncaged SFP+ slots in your equipment.

Usage recommendations

Use this refurbished Cisco SFP-10G-LR-S in compatible SFP+ ports with single‑mode LC fiber and verify link parameters after installation. For critical links, consider keeping spares and testing in your environment to ensure firmware or vendor compatibility.
