More Specification

The GLC-SX-MM= (Cisco 1000BASE-SX SFP) is a small form factor transceiver used for transmitting data over fiber optic cables. It is designed to operate at a wavelength of 850nm and can support data rates of up to 1.25 Gbps over multi-mode fiber (MMF) cable. The transceiver is compliant with the IEEE 802.3z 1000BASE-SX standard and is compatible with Cisco switches and other devices that support 1000BASE-SX SFP transceivers. It is typically used in short-range applications, such as within a campus or a building, where the distance between the transmitting and receiving devices is less than 550 meters.


The GLC-SX-MM= is a Cisco 1000 Base-SX SFP (small form-factor pluggable) transceiver module. It is designed to provide high-performance fiber connectivity for Cisco networking equipment.

1000 Base-SX is a standard for Gigabit Ethernet over fiber optic cable, and it is capable of transmitting data at a rate of 1 Gbps over a distance of up to 550 meters using multi-mode fiber.

This product is a high-performance transceiver module because it is designed to provide reliable, high-speed data transmission over multi-mode fiber. It is also backwards compatible with lower speed devices like 100Base-FX, and able to support operation over a wide range of temperatures and humidity, making it suitable for a wide range of environments.

This product is also hot-pluggable, which means it can be inserted or removed from a device without having to power down the device. This allows for easy installation and maintenance.

Compliant Standards
