The MIC-3D-40GE-TX stands out in the market with its impressive 40-port configuration, delivering unmatched connectivity density in a single modular interface card. Each port supports auto-negotiation for 10/100/1000Base-T connections through standard RJ-45 connectors, providing maximum flexibility for diverse networking requirements. The fixed optics design ensures reliable performance and eliminates the complexity of managing separate optical modules, making deployment and maintenance straightforward for network administrators.
Engineered specifically for Juniper Networks MX Series routers, this modular interface card integrates seamlessly with existing network infrastructure. The MIC 3D 40GE TX supports installation in Modular Port Concentrators (MPCs), with up to two MICs supported per MPC for enhanced scalability. This compatibility ensures organizations can maximize their investment in Juniper networking equipment while expanding their 40 Gigabit Ethernet capabilities efficiently.
Built to meet demanding enterprise networking standards, the MIC-3D-40GE-TX features hot-swappable capabilities that enable network administrators to perform maintenance and upgrades without disrupting network operations. This design significantly reduces downtime and improves overall network availability, making it an excellent choice for mission-critical environments where continuous operation is essential.
The Juniper MIC 3D 40GE features sophisticated traffic management capabilities that support rate limiting, traffic shaping, and comprehensive Quality of Service (QoS) controls. These advanced features ensure optimal performance for latency-sensitive applications and real-time communication services, making it suitable for organizations with diverse networking requirements and service-level agreements.

The 40GE TX delivers exceptional throughput with each port supporting up to 1 Gbps (1000 Mbps) data transfer rates. The modular interface card utilizes auto-negotiation and auto-MDIX functionality to provide seamless connectivity with various network devices. With 40 Gigabit Ethernet ports available, organizations can achieve substantial aggregate bandwidth to support high-traffic applications and growing network demands.
The MIC 3D 40GE TX is compatible with Juniper Networks MX Series Modular Port Concentrators, including popular models like the MX960, MX480, MX240, and other MX Series platforms. The module requires appropriate Junos OS releases for optimal functionality and supports advanced networking protocols including MPLS, BGP, OSPF, and IPv4/IPv6 dual-stack services.
When compared to other MICs in the Juniper product family, the MIC-3D-40GE-TX offers the highest port density for copper-based Gigabit Ethernet connections. The MIC-3D-20GE-SFP provides 20 SFP-based ports but requires separate optics, while the 3D 40GE TX includes fixed optics for simplified deployment. This makes the MIC-3D-40GE-TX particularly attractive for environments where copper connectivity is preferred and maximum port density is required.
The MIC-3D-40GE-TX provides 40 RJ-45 ports, each supporting 10/100/1000Base-T Gigabit Ethernet connectivity. This high port density makes it ideal for environments requiring extensive copper-based network connections. The fixed optics design eliminates the need for separate transceivers, simplifying network deployment and reducing overall equipment costs.
The MIC 3D 40GE is specifically designed for compatibility with Juniper Networks MX Series Modular Port Concentrators, including the MX960, MX480, MX240, and other MX Series models. Up to two MICs can be installed per MPC, providing flexible configuration options for network expansion. Organizations should verify specific compatibility with their existing equipment before making a purchase decision.
Most sellers provide manufacturer’s warranty coverage ranging from 1-2 years, depending on the seller and item condition. The warranty information typically covers defects in materials and workmanship, ensuring customers receive reliable networking equipment. When you purchase from authorized Juniper partners, you receive full manufacturer support and access to technical resources for troubleshooting and maintenance.
The MIC-3D-40GE-TX offers excellent value for organizations requiring high-density Gigabit Ethernet connectivity, with pricing varying based on condition (new, refurbished, or used) and seller. Many suppliers offer competitive pricing with additional services such as free shipping, technical support, and flexible return policies. Customers can save significantly compared to purchasing multiple lower-density cards while gaining the benefits of simplified management and reduced rack space requirements.
Authorized Juniper sellers typically provide comprehensive support including technical assistance, installation guidance, and troubleshooting services. Many suppliers offer same-day shipping for orders placed before cutoff times, with some providing next-business-day replacement warranties. Customers can usually contact support teams via email, phone, or live chat for assistance with configuration questions or technical issues that may arise during deployment.
At Network Republic, our end-user accounts are covered by a 1-Year Warranty on all hardware—whether New, New Open Box, New Pull, Refurbished, or Refurbished by Manufacturer —from the date of delivery.
