Cisco QSFP Transceiver Modules - Refurbished, Used, New
The Cisco QSFP Transceiver Modules deliver high-performance, multi-gigabit connectivity for dense data center and carrier environments. Designed with a compact, four-lane form factor, QSFP modules support speeds ranging from 40 Gbps, 100 Gbps, and beyond—depending on the model—making them ideal for switch-to-switch uplinks and spine-leaf topologies.
Popular variants include 40GBASE-SR4, capable of up to 100 m over OM3 and 150 m over OM4 multimode fiber, as well as QSFP BiDi models that enable plug-and-play migration over existing duplex MMF infrastructure. For higher-density needs, 100GBASE LR4, SR10, PSM4, and DR/FR options offer flexible single/multi-mode choices across shorter or extended distances. For future-ready deployments, QSFP-DD modules support next-gen performance up to 400G and 800G while maintaining backward compatibility and optimized thermal management.
QSFP modules feature a hot-swappable design and digital optical monitoring (DOM), ensuring quick installation, real-time diagnostics, and reliable performance. Their high-density, low-power design helps maximize port capabilities in rack and edge environments—delivering efficiency without compromising throughput.
At NetworkTigers, both refurbished and used Cisco QSFP Transceiver Modules are available. Refurbished units undergo rigorous testing and verification to ensure they meet performance standards. Used modules are confirmed ready for production networks, delivering reliable service from day one. Inventory is maintained in stock for fast fulfillment, orders ship quickly, and every purchase includes a 365-day warranty, giving customers long-term confidence and value.
