Nokia 7250 IXR-R6 MDA
Nokia 7250 IXR-R6 MDA: 1 x 100GE QSFP28 + 6 x 10GE SFP+ (3HE11282AA)
A high-density, flexible media-dependent adapter built for the 7250 IXR-R6 Interconnect Router — engineered for 5G anyhaul, fixed-mobile convergence, and mission-critical aggregation networks.
Service providers and enterprise network operators building out next-generation aggregation and any-haul infrastructure need line cards that combine high-speed uplinks with dense, cost-effective access ports — without sacrificing reliability in harsh or space-constrained environments. The Nokia 7250 IXR-R6 1 x 100GE QSFP28 + 6 x 10GE SFP+ MDA (part number 3HE11282AA) is purpose-built for exactly that job. It slots directly into the Nokia 7250 IXR-R6 Interconnect Router chassis and delivers a single 100 Gigabit Ethernet uplink alongside six 10 Gigabit Ethernet ports, giving network architects a clean, efficient way to aggregate multiple 10GE services onto a single high-capacity core-facing link.
This card is part of Nokia’s broader 7250 IXR-R series MDA portfolio, which is designed for network longevity: as bandwidth demand grows, operators can adapt port configurations without forklift-upgrading the entire chassis. Below, we break down the key specifications, use cases, and everything you need to know before requesting a quote.
Port Bandwidth at a Glance
The visual below illustrates how the card’s total bandwidth is distributed between the single 100GE uplink and the six 10GE access ports (160 Gb/s theoretical aggregate vs. actual port speeds):
Bars scaled relative to the 100 Gb/s uplink port. A single 100GE trunk can comfortably aggregate all six 10GE access ports with substantial headroom for growth.

Why Choose This MDA?
5G-Ready Anyhaul
Delivers the low latency and precision timing (SyncE, IEEE 1588v2, GNSS) required for fronthaul, midhaul, and backhaul in 4G/5G networks.
Efficient Aggregation
Six 10GE ports uplink cleanly onto a single 100GE trunk, simplifying access-to-core network design and reducing core port count.
Extended Temperature Range
Rated for -40°C to +65°C sustained operation, ideal for outdoor cabinets, cell sites, and industrial/utility environments.
Modular & Future-Proof
Part of a flexible MDA family spanning 1GE to 100GE, letting operators mix port types per slot as bandwidth needs evolve.
Carrier-Grade Resiliency
Supports control-plane HA, MC-LAG, LSP/pseudowire redundancy, and fast reroute for near-zero downtime networks.
Automation-Friendly
Managed by Nokia SR OS with NETCONF, MD-CLI, and gRPC support, plus Nokia NSP for streamlined service orchestration.
Common Deployment Scenarios
- Mobile aggregation sites — consolidating multiple 10GE cell-site links onto a single 100GE backhaul connection toward the core.
- Fixed-mobile convergence (FMC) — carrying both fixed broadband and mobile transport traffic on shared, QoS-differentiated infrastructure.
- Utility and railway networks — hardened for substations and trackside cabinets per IEEE 1613 and EN 50121-4.
- IP/MPLS edge and metro aggregation — acting as a compact, high-density access node feeding into larger core routers.
- IoT and mission-critical operational networks — supporting simultaneous business (IT) and operational (OT) traffic with strict SLAs.
