SFP module Cisco GLC-EX-SMD

The Cisco 1000BASE-EX SFP Module (model GLC-EX-SMD) is a Small Form-Factor Pluggable Gigabit Ethernet transceiver designed for fiber-optic network links. It supports a maximum data rate of 1000 Mbit/s, is hot-swappable for easy replacement without powering down equipment, and is compatible with Cisco ME 3400 and Cisco Catalyst 3750 platforms. The module is covered by a 5-year standard warranty and is manufactured in China.

Advantages

The module uses an industry-standard SFP form factor to ensure broad compatibility with supported Cisco switches and routers. Its hot-swappable design reduces downtime during maintenance or upgrades. The transceiver supports gigabit speeds over fiber, providing reliable long-distance connectivity and stable data transfer performance for network deployments.

Suitable for

• Connecting Gigabit Ethernet switches and routers over single-mode fiber
• Network backbone and campus links requiring 1000 Mbit/s throughput
• Service provider and enterprise access networks using Cisco ME 3400 or Catalyst 3750

How to use

Power off the switch or router if recommended by the device manufacturer, then insert the SFP transceiver into an available Gigabit Ethernet SFP port until it latches. For hot-swappable platforms, the module can be inserted or removed while the system is powered on; follow the host device instructions for safe hot-swap operations. Connect the appropriate single-mode fiber cable to the transceiver’s optical port, ensuring correct transmitter/receiver alignment. Verify link status on the host device and configure interfaces as required for your network.

Recommendations

Use this module with compatible Cisco platforms listed by the manufacturer, maintain clean fiber connectors to prevent signal degradation, and follow Cisco guidelines for optical power budget and maximum link distance. Store and handle the transceiver in an electrostatic-safe environment and use protective dust caps when ports are not connected.
