Compatibility with industry-standard QSFP28 interfaces facilitates interoperability across compatible switching and routing platforms.
Suitable for
 Data center spine-leaf and rack-to-rack links over multimode fiber
 Server uplinks to top-of-rack and aggregation switches
 High-speed switching fabrics and interconnects requiring 100 Gbps bandwidth
 Short-range multimode fiber runs in enterprise and colocation environments
Key specifications
 Form factor: QSFP28 (compact, four-lane electrical/optical interface)
 Data rate: 100 Gbps aggregate
 Optical interface: SR4 for short-range multimode fiber
 Fiber type: Multimode fiber (MMF)
 Installation: Hot-pluggable module for in-service insertion and removal
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port following the host equipment manufacturer’s guidance, ensuring proper orientation and a secure latch. Use appropriate multimode fiber patch cords and follow recommended cable routes to minimize bend radius and loss. Verify link status through the host device management interface and monitor optical parameters as provided by the platform to confirm correct operation.
Usage recommendations
