QSFP-100G-LR, Juniper QSFP28 Transceiver, 100GBASE-LR1/10km SMF/LC Connector

The Juniper QSFP-100G-LR is a high-performance 100G optical transceiver module designed for carrier-grade and enterprise backbone networks. This Juniper transceiver uses the QSFP28 form factor and supports the 100GBASE-LR1 interface over single-mode fiber, making it suitable for regional deployments across Asia, Europe, Africa, and North America. It delivers a 100 Gbps data rate over SMF (Single-Mode Fiber) with a maximum transmission distance of 10 km, ideal for leaf-spine data center links, metro aggregation, or inter-building campus connections. The module operates at a 1310 nm wavelength and uses a Duplex LC connector, which is widely adopted and easy to integrate into existing fiber infrastructures. With typical power consumption below 3.5W, it helps distributors and system integrators build energy-efficient high-density 100G solutions.

For network engineers and SMB integrators, the QSFP-100G-LR offers a hot-pluggable design and a CAUI-4 electrical interface, simplifying upgrades from 40G or 10G to 100G without major changes in cabling. Digital Diagnostic Monitoring (DDM) is supported, allowing real-time tracking of optical power, temperature, and voltage to reduce troubleshooting time and improve service availability. The module is MSA compliant and meets relevant international regulatory standards, giving regional distributors confidence for cross-border deployments and tenders. With an MTBF over 300,000 hours, it is suitable for data centers, cloud service platforms, and service provider networks that require stability and predictable lifecycle planning.

Because the Juniper QSFP-100G-LR is fully compatible with Juniper switches and routers, it integrates smoothly into existing Juniper-based infrastructures used by enterprises, carriers, and public sector networks. This ensures consistent performance, vendor-backed interoperability, and simplified support. Non-native English users will find deployment straightforward thanks to standard interfaces and familiar LC/SMF design, while procurement teams benefit from clear global standards compliance for RFPs in different regions. Whether for new 100G backbone builds or incremental upgrades, the Juniper QSFP-100G-LR helps reduce per-bit transport cost while keeping the optical layer simple, reliable, and easy to manage.
