Cisco DPX20/X10 Pluggable 4x10G-BP LR NIC Module

Expand DPX20/X10 systems with four 10 GbE long-reach connections in a pluggable module format designed for enterprise network architectures. The RD21-4X10GBPLR-1Y gives infrastructure teams a compact way to add high-speed Ethernet capacity without moving to a larger chassis or overcommitting to unused ports. This module is a strong fit for environments where predictable throughput and clean physical integration matter. Long-reach 10 GbE connectivity supports distributed racks, aggregation layers, and server-side network attachment where cabling distance and port density both affect design. The pluggable form factor also helps simplify platform planning by keeping the expansion path aligned with the host system. For teams standardizing on Cisco hardware, this module offers a targeted way to scale connectivity while preserving the operational model of the underlying DPX20/X10 platform. It is a practical choice when you need more bandwidth, controlled port growth, and a deployment profile that supports enterprise procurement and lifecycle planning.
