Key specifications
Data rate: 100 Gbps
Interface type: MPO
Fiber type: Multimode
Maximum reach: 100 meters
Form factor: QSFP28
How to use
To install the transceiver, ensure that the network device is powered on or prepared for hot-swapping according to the manufacturer's guidelines. Carefully insert the module into the designated QSFP28 port until it clicks into place. Once installed, connect the appropriate MPO multimode fiber optic cable to the transceiver interface. The network device should automatically detect the module and initialize the link, allowing for immediate data transmission.
What to consider before purchase
Verify compatibility with your specific switch or server model
Ensure the existing cabling infrastructure supports MPO multimode connections
