Palo Alto QSFP-100G-ER4 transceiver

This new QSFP28 transceiver module supports 100GBASE-ER4L signalling for long-range data centre links. It operates at 1310 nm over OS2 single-mode fibre with duplex LC connectors and reaches distances up to 40 km. Digital optical monitoring is included for link diagnostics.

Compatibility and fibre checks

Verify that the host port accepts QSFP28 modules and supports the 100GBASE-ER4L standard before ordering. Confirm the link uses OS2 single-mode fibre with duplex LC patching and that the total channel length stays within the 40 km reach. Ensure both ends of the link run compatible optics.

Highlights

  • 100 Gbps throughput for high-bandwidth links
  • 40 km reach over single-mode fibre
  • 1310 nm wavelength for long-distance transmission

Questions about this item

Does the Optdex Palo Alto QSFP-100G-ER4 arrive with the duplex LC cables needed for the 40km link?

The module ships with the transceiver only; OS2 single-mode patch cords with duplex LC connectors must be purchased separately.

Should I choose the 100GBASE-ER4L version for a 40km run at 1310nm?

Yes, the ER4L designation matches the 40km reach over OS2 fibre at 1310nm, making it the correct variant for that distance.
