Nokia 7250 IXR 48-Port 10GbE SFP+
Nokia 7250 IXR 48-Port 10GbE SFP+ + 2-Port 100GbE QSFP28 Integrated Media Module
A high-density access line card built for the 7250 IXR and 7750 SR ecosystem, pairing dense 10GbE port count with 100GbE uplink capacity and built-in MACsec encryption.
Overview
The Nokia 7250 IXR 48-port 10G SFP+ + 2-port 100G QSFP28 Integrated Media Module (part number IMM48-SFP+2-QSFP28, Nokia SKU 3HE11753AA) is a line card built for chassis-based platforms in Nokia’s 7250 IXR and 7750 SR router families. Rather than a fixed-form-factor box, this is a modular IMM designed to slot into supported chassis slots, giving network operators a way to add high-density 10GbE access capacity with dedicated 100GbE uplinks without deploying a separate standalone switch.
This module sits at the intersection of two closely related Nokia product lines. The 7250 IXR family and the 7750 SR family share a common satellite architecture — several 7250 IXR variants can operate as Ethernet satellite extenders off a 7750 SR host chassis, extending port capacity while the 7750 SR handles centralized control-plane and routing functions. A 48-port 10GbE module with 100GbE uplinks is a natural fit for that role: dense edge or access-layer termination, aggregated upstream into the SR core.
Built-in MACsec support is the other headline feature. Encrypting traffic at line rate, in hardware, on a dense 10GbE access card means operators can extend secure transport out to the network edge — cell sites, aggregation nodes, or interconnect points — without adding a separate encryption appliance or absorbing a throughput penalty from software-based encryption.
Bandwidth & Port Capacity
The module’s port layout is built around a straightforward access-to-uplink relationship: 48 ports of 10GbE facing the access or aggregation side, and 2 ports of 100GbE facing the uplink or core side.
Front-Panel Bandwidth Breakdown
Access-to-Uplink Oversubscription Ratio
A theoretical 2.4:1 oversubscription ratio at full line rate across all 48 access ports — typical and expected for access/aggregation cards where traffic is rarely fully utilized simultaneously across every port.
Key Capabilities
48× 10GbE SFP+ Access
Dense SFP+ port count for aggregating 10GbE-connected servers, cell sites, or downstream switches onto a single module.
2× 100GbE QSFP28 Uplink
High-capacity uplink ports for connecting into core or aggregation routers without a separate uplink card.
Hardware MACsec
IEEE 802.1AE line-rate encryption in hardware, extending secure transport to the network edge without a throughput penalty.
Integrated Media Module Form Factor
Designed to install into supported 7250 IXR and 7750 SR chassis slots, adding capacity to an existing modular deployment.
7750 SR Satellite Ecosystem
Fits within Nokia’s Ethernet Satellite architecture, where 7250 IXR platforms extend port capacity off a 7750 SR host for centralized control.
SR OS Software Base
Operates under Nokia’s SR OS, giving operators a consistent CLI and feature set across the broader 7250 IXR / 7750 SR portfolio.
