The Cisco C3KX-NM-1G Network Module adds one Gigabit Ethernet SFP port to Catalyst 3K-X series switches, increasing their connectivity and versatility.

The Cisco GLC-ZX-SMD SFP Transceiver Module is intended for long-distance Gigabit Ethernet applications, enabling distances of up to 80 kilometers with real-time Digital Optical Monitoring (DOM). It operates at 1550 nm and provides high-performance communication via single-mode fiber (SMF).

The Cisco GLC-LH-SM SFP Transceiver Module is a small, hot-swappable optical transceiver designed for Gigabit Ethernet and Fiber Channel applications. It operates on single-mode fiber (SMF) and can transmit data across distances of up to 10 kilometers, making it excellent for extended reach in networking situations. With its dependability, compatibility, and ease of installation, it's an adaptable solution for high-performance optical communication.

The Cisco C3850-NM-4-10G Network Module expands Cisco Catalyst 3850 Series switches with four 10 Gigabit Ethernet ports, enhancing network connectivity and performance.
