QSFP56 optical transceivers move data very fast at 200G speeds. They work well for busy data centers. These modules can be swapped while the network is running. Updated: September 24, 2024 The Cisco ® family of QSFP modules provide solutions for AI/ML data center applications, Network Interface Cards (NICs) on servers, and for data center switches, while leveraging the breakout capabilities and backward compatibility to lower-speed QSFP pluggable modules. Use the Compatibility Tool to verify FS transceiver compatibility with your device and access test reports. The. At the heart of this transition is a critical component: the QSFP56 optical transceiver. If you're planning an upgrade or simply future-proofing your infrastructure, understanding this technology is crucial. They work. QSFP56 Optical Transceiver is an InfiniBand 200Gb/s Single-port QSFP56, SR4 multimode parallel transceiver using a single, 4-channel MPO-12/UPC optical connector using OM4 multimode fiber (MMF) with a wavelength of 850nm up to 100 meters.
