100G QSFP28 Optical Transceivers for Data Center Links

Our 100G QSFP28 transceiver selection supports high-speed switch uplinks, spine-leaf fabrics, storage networks, and other 100GbE deployments. Choose the optical interface according to the host equipment, fiber plant, required reach, and connector type. A correct match considers the entire link rather than the module form factor alone.

How to select a 100G QSFP28 module

  • Confirm that the host port is a 100G QSFP28 port and verify its supported operating mode.
  • Match the fiber: multimode for short-reach SR4 or CSR4 links; singlemode for longer LR4 or ER4 designs.
  • Check connector type, polarity, patch-panel path, and the total link distance.
  • Confirm the required coding or compatibility for the switch, router, or network adapter.
