Juniper CFP2-100G-ER4-D 100G ER4 Transceiver | LC, Single-Mode, 40 km

Keep long-reach Ethernet links stable with the Juniper CFP2-100G-ER4-D transceiver. Built for 100GBase-ER4 deployments, this hot-pluggable CFP2 module is designed for optical network and data networking environments where reach, signal integrity, and interoperability matter. Its LC connector interface and single-mode fiber support make it a practical fit for metro aggregation, campus backbones, and other extended-distance links that need 100 Gigabit Ethernet performance without unnecessary complexity. With support for distances up to 40 km, this module addresses the gap between short-reach optics and more expensive transport options. That makes it well suited for infrastructure teams standardizing on Juniper platforms and looking for a dependable transceiver that aligns with enterprise network design requirements. The dual-port configuration and ER4 optics help maintain a clean deployment profile while supporting the throughput expected in high-capacity environments. For teams evaluating optics at scale, this module offers a clear value proposition: long-distance 100 GbE connectivity in a compact, hot-swappable form factor. It is a strong choice when the network design calls for predictable reach, single-mode fiber, and a vendor-matched optic that fits operational standards.
