1G SFP Mini GBIC Transceiver Modules

An SFP module, or Small Form-factor Pluggable, is a compact, hot-swappable transceiver that converts electrical signals to optical signals and vice versa. It plugs into an SFP port on a network switch, router, or other device to connect it to fiber optic or copper networking cables. This modular design allows for easy network upgrades and changes without replacing the entire device.

Absolutely. Every refurbished SFP module we sell undergoes a rigorous 5-step quality assurance and testing process to ensure it meets or exceeds original manufacturer specifications for performance and reliability. We stand behind our products with a comprehensive warranty, giving you peace of mind and dependable connectivity for your critical network infrastructure at a lower cost.

The primary difference is the type of fiber optic cable they are designed for, which dictates the transmission distance. Multi-mode (MMF) SFPs use a larger core cable and are ideal for short-range connections, typically up to 550 meters, within a data center. Single-mode (SMF) SFPs use a smaller core cable for long-range transmissions, often reaching 10 kilometers or more, connecting different buildings or sites.

Compatibility is crucial. Our SFP modules are coded to be compatible with specific brands, such as Juniper or Brocade, as listed in the product details. To ensure a module will work with your hardware, match the product's compatible brand with your switch model. If you are unsure, our technical support team can help verify compatibility before you purchase.

We provide a rock-solid warranty on all our refurbished SFP transceivers. While the specific duration can vary, every unit is backed by our commitment to quality. This includes support and a Return Merchandise Authorization (RMA) policy for any defective units found during the warranty period, ensuring you receive a functional, reliable product.

Yes, we do. In addition to fiber optic modules, we offer 1000Base-T SFP transceivers that feature a standard RJ-45 connector. These are designed for use with copper Ethernet cables (like Cat5) and provide 1 Gigabit connectivity over distances up to 100 meters. They are an ideal solution for connecting devices that do not have fiber optic interfaces.
