📋 The Cisco C3850-NM-4-10G is a high-performance 4-port 10 Gigabit Ethernet SFP+ network module designed to enhance the uplink capabilities of Cisco Catalyst 3850 Series managed switches. Engineered for enterprise, campus, branch office, and data centre environments, this modular expansion card provides high-speed fibre connectivity, enabling businesses to meet increasing bandwidth demands while maintaining exceptional network reliability and scalability.

Equipped with four SFP+ (Small Form-Factor Pluggable Plus) slots, the C3850-NM-4-10G supports both 10 Gigabit Ethernet SFP+ transceivers and 1 Gigabit SFP modules, allowing organizations to deploy either 1GbE or 10GbE uplinks without replacing existing fibre infrastructure. This flexibility enables seamless network upgrades while protecting previous investments in Gigabit networking equipment.

Designed specifically for compatible Cisco Catalyst 3850 Series switches, the module supports high-speed uplinks to distribution switches, core networks, servers, storage systems, and data centre infrastructure. Its modular hot-pluggable design allows easy installation and future expansion without replacing the entire switch, reducing deployment costs and simplifying network growth.

The Cisco C3850-NM-4-10G delivers wire-speed performance, low latency, and high availability, making it ideal for bandwidth-intensive applications such as virtualization, cloud computing, unified communications, IP surveillance, enterprise Wi-Fi, multimedia streaming, and large-scale data transfers. When combined with Cisco IOS Software, the module supports advanced Layer 2 and Layer 3 networking features, Quality of Service (QoS), VLANs, multicast, IPv4/IPv6 routing, and enterprise-grade security policies.

Whether expanding an enterprise campus network, upgrading branch office connectivity, or deploying high-speed fibre aggregation, the Cisco C3850-NM-4-10G provides a reliable, scalable, and future-ready 10 Gigabit uplink solution for modern business networks.
