On which device is the XFP optical module plugged into

An XFP optical module is plugged into a dedicated XFP port on a network switch, router, or I/O module.

XF

P modules are 10-gigabit small form-factor pluggable transceivers that convert electrical signals from the host device into optical signals for fiber optic transmission. They are designed to be hot-swappable, allowing installation or replacement without powering down the system. The host device must have a physically compatible XFP slot, as XFP modules are larger than SFP or SFP+ modules and cannot fit into those ports.

Typical Host Devices

Network Switches: Many enterprise and carrier-grade switches have dedicated XFP ports for 10 Gigabit Ethernet connections. Routers: High-speed routers use XFP modules to connect to optical networks, supporting protocols like 10G Ethernet, OC-192, or OTU-2.

I/

O Modules: Some modular systems include XFP-capable I/O cards to expand optical connectivity without replacing the entire chassis. Key FeaturesLC Duplex Connector: XFP modules typically use LC fiber connectors for high-density optical connections.

Hot-

Swappable: They can be inserted or removed while the host device is powered on, minimizing network downtime. Dedicated Ports: XFP modules require dedicated XFP slots; they are incompatible with SFP/SFP+ ports due to size and pin differences. In summary, an XFP optical module is always plugged into a dedicated XFP port on a compatible switch, router, or I/O module, providing high-speed optical connectivity for 10 Gigabit networks.
