Sort by

The Cisco Transceiver Modules family delivers reliable, high-performance optical and copper connectivity for enterprise, data center, and service provider networks. Designed to cover a wide range of interfaces, these modules ensure seamless operation across switching, routing, and storage platforms.

This collection includes popular options such as GLC SFP modules for Gigabit Ethernet, available in both multimode and single-mode variants to support short- and long-range links. For higher bandwidth needs, SFP+ modules provide 10 Gbps performance, making them a mainstay for aggregation layers, server access, and high-speed uplinks.

For modern large-scale environments, QSFP modules deliver 40 Gbps to 100 Gbps connectivity, while next-generation QSFP-DD technology supports 400 Gbps and beyond for spine-leaf architectures and dense data centers. Legacy solutions, such as X2 transceivers and CFP modules, remain available for compatibility with earlier platforms, helping customers protect their prior investments while supporting scalable growth.

At NetworkTigers, both refurbished and used Cisco Transceiver Modules are available. Refurbished units undergo rigorous testing and verification to ensure they meet performance standards. Used units are confirmed ready for production networks, providing reliable performance from day one.
