3HE10311AA ALCATEL Nokia 7750 SR / 7950 XRS Router Line Card

The Alcatel 3HE10311AA is a Media Dependent Adapter (MDA) module designed for Nokia (formerly Alcatel-Lucent) 7750 Service Router and 7950 XRS platforms. This high-density module provides 100 Gigabit Ethernet connectivity using QSFP28 optical interfaces, enabling high-bandwidth service delivery and network aggregation.

This MDA is deployed within carrier-grade routing platforms to support demanding applications such as mobile backhaul, metro Ethernet services, data centre interconnect, and core network aggregation. The 100GE interfaces provide the throughput required for modern high-capacity networks.

The 7750 SR and 7950 XRS platforms remain widely deployed in service provider and large enterprise networks globally. As network operators continue to expand capacity, compatible MDAs such as the 3HE10311AA are essential for scaling existing infrastructure without full platform replacement.
