HPE Juniper Networking

HPE Juniper Networking QSFP-100G-ZR4 100Gbps 80km SFP transceiver

SKU CH-KD4B-TB4YQ

A 100Gbps QSFP28 transceiver reaching 80km over single-mode fibre at 1310nm with under 3.5W draw

  • Device TypeTransceiver
  • 100Gbps throughput for high-capacity links
  • 80km reach over single-mode fiber at 1310nm
  • QSFP28 form factor fits existing ports
  • Under 3.5W power draw cuts energy cost
  • LC duplex connector for standard patch cables

100Gbps QSFP28 transceiver for long-haul links

This HPE Juniper Networking QSFP-100G-ZR4 is a new 100Gbps optical transceiver built for single-mode fiber runs up to 80km. It plugs into standard QSFP28 ports and uses LC duplex connectors at a 1310nm wavelength. Network engineers and data-centre operators choose it when they need to bridge campuses or metro rings without intermediate amplification.

Capacity headroom at 100Gbps over 80km

The module delivers a full 100Gbps lane rate across the entire 80km reach on single-mode fiber, making it suitable for dense wavelength-division multiplexing or direct point-to-point links. Power draw stays below 3.5W, so thermal headroom remains generous inside crowded line cards. Beyond the rated 80km distance or on multimode fiber the link budget is exhausted and errors rise sharply.

QSFP28 slot integration and fiber planning

The transceiver fits any QSFP28 cage that accepts LC duplex single-mode patch cords, requiring no proprietary cabling or firmware locks beyond standard Juniper qualification. Its sub-3.5W profile frees power budget for adjacent ports in high-density chassis. Builds that need shorter reach, multimode support, or bidirectional single-fiber operation must select a different module.

Questions about this item

Will this QSFP28 module fit the same ports as my existing QSFP28 100Gbps equipment?

Yes, the QSFP28 form factor matches standard QSFP28 ports, so it installs directly alongside other 100Gbps QSFP28 transceivers.

How can I confirm the link is operating at the specified 100Gbps over 80km after installation?

Check the switch port statistics for a 100Gbps link speed, verify the receive optical power is within the expected range for 80km single-mode fiber, and confirm zero bit errors on the interface counters.

Does the shipment include the LC duplex patch cords needed for single-mode fiber, or must they be ordered separately?

The transceiver ships with the QSFP28 module only; LC duplex single-mode patch cords are not included and must be purchased separately.
