Modules

Modules is the home of pluggable network modules, split four ways: Optical Transceivers for SFP, SFP+, SFP28, QSFP+, QSFP28 and CFP optics on Ethernet and Fibre Channel; Switch Expansion Modules for Juniper EX uplink modules, Cisco network modules and line cards; Stacking Cables for Cisco StackWise and Dell switch stacks; and Routing Modules for Juniper MX interface cards and control boards. Choose an optic by port form factor and reach, an uplink module by switch model, and a stacking cable by the stacking technology of the switches it joins.

Network modules by device type

A network module adds ports or functions to a switch or router built to take it, and the module types are not interchangeable across device types:

Module typeDevice it fitsWhat it does
Switch network or uplink moduleModular switches such as the Cisco Catalyst 9300 and Juniper EX3200, EX4200 and EX4300Adds uplink ports at 1G, 10G, 25G, 40G or multigigabit, by module
Switch expansion moduleJuniper EX4550 and EX4600Adds 10G or 40G ports, or Virtual Chassis links
Router interface module (NIM, SM-X)Cisco ISR 4000 routersAdds WAN, LAN or service interfaces in NIM and SM-X slots
Modular interface card (MIC)Juniper MX routers, inside a modular port concentrator (MPC)Supplies the physical ports; the MPC forwards the packets
Optical transceiverAny SFP, SFP+, SFP28, QSFP+ or QSFP28 portTurns the port into an optical or copper link of a given standard
Stacking cableSwitches with a stacking systemJoins several switches into one stack

Each module fits its own family: Cisco ties 9300X network modules to 9300X switches, Juniper lists a first Junos OS release for each EX4300 uplink module, and Juniper's MX routers take up to two MICs of different media types in one MPC when the MPC supports them. Many of these modules swap without powering down: Cisco calls its 3750-X network modules hot-swappable, and Juniper calls its MICs hot-removable and hot-insertable.
