Juniper MX Series Interface Cards & Routing Engines

Juniper MX Series interface cards provide the physical and logical connectivity that powers the MX platform’s role as a universal routing, transport, and edge services solution. BrightStar Systems carries a wide range of used and refurbished Juniper MICs, MPCs, routing engines, and next-generation line cards for MX routers including the MX240, MX480, MX960, MX10003, MX10008, and MX10016.

All interface cards we sell undergo full testing, inspection, and a factory-default reset, and are backed by our 1-Year In-House Warranty. Whether you're expanding capacity, adding new service types, upgrading port density, or maintaining an existing MX deployment, this page serves as your central hub for Juniper MX Series interface cards.

Juniper MX Interface Cards Overview
Juniper MX routers support multiple generations of modular interface cards depending on chassis size and performance requirements. These cards enable scaling from 1GbE access to 400GbE core routing, support advanced L2/L3 services, and are central to the MX platform’s longevity and flexibility.

Modular Port Concentrators (MPCs): High-performance line cards providing forwarding capacity, deep buffers, hierarchical QoS, and flexible port combinations.
Modular Interface Cards (MICs): Physical interface modules that slot into MPCs and provide SFP/SFP+, SFP28, QSFP+/QSFP28, and other port types.
Routing engines (REs): Control-plane modules used to manage chassis resources, routing protocols, and services.
Next-generation line cards: High-capacity cards such as the JNP10003-LC2103 for MX10003, which provide massive 100G/400G scale.

Together, MPCs, MICs, REs, and line cards allow MX routers to scale bandwidth, services, and subscriber capacity across edge, core, and metro applications.
Key Features of Juniper MX Interface Cards

Flexible speed options: 1GbE, 10GbE, 25GbE, 40GbE, 100GbE, and 400GbE depending on card family.
Modular scalability: Mix different MICs within MPCs to customize port density and service capabilities.
Advanced forwarding: Deep buffers, HQoS, and rich L2/L3/MPLS services for edge and core deployments.
High availability: Redundant RE support, ISSU, and non-stop routing/switching features for maximum uptime.
EVPN-VXLAN & segment routing: Supported on many modern MPC/MIC generations with appropriate Junos OS versions.
Long lifecycle value: MX interface cards remain deployable across multiple router generations and chassis sizes.

Compatibility Across MX Platforms
Juniper interface card compatibility varies by chassis generation and RE/SCB support. BrightStar Systems can assist in verifying compatibility with:

MX240 / MX480 / MX960 – Modular routers supporting multiple MPC/MIC generations.
MX2008 / MX2010 / MX2020 – High-scale core and edge platforms with advanced MPC options.
MX204 – Compact fixed system complemented by MX interface cards deployed elsewhere in the network.
