100 Gbps QSFP28 LR4 transceiver for Juniper, 10 km single-mode reach at 1310 nm

  • 100 Gbps throughput for high-speed networks
  • 10 km reach over single-mode fibre
  • 1310 nm wavelength suits long-haul links
  • Hot-pluggable LC duplex for quick installs
  • DOM support via I2C enables real-time monitoring

100G QSFP28 LR4 Juniper module

This accessory is a 100GBASE-LR4 QSFP28 optical transceiver coded for Juniper Networks JNP-QSFP-100G-LR4 compatibility. It targets network engineers upgrading Juniper switches or routers with single-mode 10 km links. The module operates at 1310 nm over LC duplex connectors and supports hot-pluggable installation. It is not for buyers who need multimode SR4 reach or non-Juniper coded optics.

Hot-pluggable LC duplex and DOM

The LC duplex connector enables direct patching to existing single-mode fibre plant without adapter cables. Hot-pluggable insertion allows link changes without powering down the chassis, reducing maintenance windows. Digital optical monitoring via the I2C interface exposes real-time temperature, voltage and optical power data to the host system. These features remove the need for external diagnostic gear during commissioning.

IEEE 802.3bm and CAUI-4 compliance

The transceiver follows IEEE 802.3bm 100GBASE-SR4 and CAUI-4 electrical specifications, ensuring interoperability with compliant Juniper line cards. A metal housing and spring-loaded latch survive repeated insertions in dense patch panels. LC duplex ferrules stay clean behind the spring-loaded dust caps when not cabled. The mechanical design fits standard QSFP28 cages without forcing adjacent ports.

Questions about this item

Will the LC duplex connector or the QSFP28 module need periodic cleaning or replacement in a 10km single-mode link?

The LC duplex connector on the QSFP28 module should be inspected and cleaned with lint-free wipes and isopropyl alcohol whenever links are disconnected; the module itself is hot-pluggable and rated for long-term 100Gbps operation without scheduled replacement.

What thermal or power limit appears first when the transceiver runs continuously at 100Gbps over 10km?

The module operates at 1310nm over single-mode fibre up to 10km and draws power within the QSFP28 MSA envelope; sustained line-rate traffic keeps it within its specified thermal design without throttling.

How much heat and fan noise does the transceiver add to a Juniper chassis running all day?

The QSFP28 LR4 module is a passive optical device with no internal fan; it dissipates low power within the MSA limit, so it adds negligible heat and zero acoustic noise to the chassis airflow.
