Juniper SFP56-DD 100G ER Transceiver | 100G, SFP56-DD, Enterprise

Keep long-reach 100 GbE links stable with the Juniper SFP56-DD 100G ER transceiver. This module uses the SFP56-DD form factor to support dense switching platforms while addressing optical runs that exceed short-reach requirements. The ER profile is suited to enterprise and data-center interconnects where fiber spans are longer and the network design depends on clean optical performance across more demanding paths. It is a practical choice for teams building around 100G aggregation, switch interconnects, and fabric extensions that need more reach without moving to a different speed tier. For infrastructure buyers, this is the kind of optic that earns its place by matching the link budget to the application. It helps avoid overbuying on unnecessary transport gear while still meeting the reach and throughput expectations of production Ethernet. In environments where downtime is expensive and port density matters, the right transceiver is not a commodity — it is part of the network design.
