CFP2 100G LR4 Transceiver Juniper Networks 100GBASE-LR4 | Enterprise Optics

Move 100 GbE traffic across longer fiber spans with the Juniper CFP2 100G LR4 transceiver. This module is intended for network teams that need long-reach optical transport without sacrificing compatibility or link discipline. It is a practical fit for backbone, aggregation, and inter-building connections where the optical layer must stay predictable under production load. The CFP2 form factor supports dense deployments in platforms designed for high-speed optics, while the LR4 design aligns with single-mode fiber environments that require extended reach. That makes it well suited for campus backbones, data center interconnects, and other links where short-reach modules are not enough. Choosing the right long-reach optic matters because the cost of a failed or marginal link is rarely limited to the transceiver itself. This Juniper module helps teams standardize on a known optical profile for critical paths, reducing uncertainty when the network design depends on stable 100 GbE transport over distance.
