When selecting a 100G SR4 module, consider:

• Transmission distance

• Fiber type (OM3/OM4)

• Connector type

• Switch compatibility

• Power consumption

• Operating temperature

Choosing the right module ensures reliable performance and future network scalability.

Q8: Why choose the C-LIGHT 100G QSFP28 SR4 100m transceiver?
