Juniper SFP56-DD 100G SR BIDI Transceiver | SFP Module, Enterprise

Maintain 100 GbE connectivity across short-reach multimode links with the SFP56-DD 100G SR BIDI transceiver. Designed for dense switching environments, this optic supports bidirectional transmission over duplex fiber, helping reduce cabling complexity while preserving the throughput required for leaf-spine fabrics, aggregation layers, and high-performance server uplinks. The compact SFP56-DD form factor is built for modern platforms that need more bandwidth per rack unit without sacrificing serviceability. Hot-swappable optics simplify maintenance windows, while the SR BIDI design is well suited to short-distance interconnects inside the data center where low-latency transport and clean fiber management are priorities. For teams standardizing on Juniper infrastructure, this transceiver provides a straightforward way to extend 100G links across multimode fiber without moving to more expensive long-reach optics. It is a practical choice when you need high port density, controlled reach, and a deployment profile that fits tightly packed switching systems. Use it to keep critical traffic flowing between racks, rows, and adjacent network tiers with the optical headroom expected in enterprise environments.
