HPE Juniper Networking

HPE Juniper Networking QSFP-100G-LR4-C 100Gbps 1310nm 10km QSFP28 SFP transceiver

SKU CH-1K7H-YPBVS MPN QSFP-100G-LR4-C

A 100Gbps QSFP28 transceiver operating at 1310nm for 10km Ethernet links on single-mode fibre

  • Device TypeTransceiver
  • 100 Gbps throughput over single-mode fibre
  • 10 km reach at 1310 nm wavelength
  • QSFP28 form factor fits standard ports
  • 3 V supply simplifies power design
  • 28 Gbps per lane enables high-density links

100Gbps QSFP28 transceiver for 10 km links

The HPE Juniper Networking QSFP-100G-LR4-C is a 100Gbps QSFP28 transceiver designed for 10 km single-mode fibre links at 1310 nm. It suits data-centre and campus networks that need long-reach 100G Ethernet connectivity.

Fits QSFP28 ports with 3.3 V supply

The module plugs into any QSFP28 port that provides a 3.3 V supply and supports 100GBASE-LR4. Each of the four lanes runs at 28 Gbps, freeing the host from lane aggregation while delivering full 100 Gbps throughput over a duplex LC patch cord.

Replaces shorter-reach 100G optics

It upgrades from 100GBASE-SR4 or CWDM4 modules when the link exceeds 100 m or 2 km respectively. The jump is worth it when the fibre route is up to 10 km and the budget allows single-mode infrastructure.

Highlights

  • 100 Gbps throughput over single-mode fibre
  • 10 km reach at 1310 nm wavelength
  • QSFP28 form factor fits standard ports
  • 3 V supply simplifies power design
  • 28 Gbps per lane enables high-density links

Questions about this item

What is the maximum link distance the QSFP-100G-LR4-C supports at 100 Gbps over single-mode fibre?

The transceiver is rated for 10 km reach using 1310 nm optics on single-mode fibre.

What power draw and heat should be expected when the module runs continuously at 100 Gbps?

It operates from a 3.3 V supply with each lane at 28 Gbps, so sustained power stays within the QSFP28 low-power class.

Which port type and fibre patch cables are required to connect this transceiver?

It plugs into a QSFP28 cage and needs duplex LC single-mode patch cords for the 1310 nm LR4 interface.
