Description

The GLC-SX-MMD is a Gigabit Interface Converter (GBIC) module manufactured by Cisco. It is used for providing high-speed fiber optic connections over short distances, typically for network expansion or linking two network devices in an enterprise setting.

Key Features:

• Form Factor: It is a small, hot-swappable, transceiver module, compatible with Cisco devices that have a GBIC or SFP slot.

• Transmission Speed: It supports 1 Gigabit Ethernet (1GbE).

• Interface: LC Duplex connector.

• Wavelength: Typically operates with 850 nm wavelength for short-range connections.

• Distance: The GLC-SX-MMD can transmit over multimode fiber (MMF) at distances of up to 550 meters depending on the fiber type and network conditions.

• Compliance: Compliant with IEEE 802.3z standards for Gigabit Ethernet, which guarantees compatibility with various networking devices.

• Power: Powered by the host device through the SFP slot, no external power supply needed.

• Temperature: Designed to operate in standard commercial temperature ranges (usually 0°C to 70°C).

Applications:

• Short-distance fiber-optic links between network switches, routers, and other devices.

• Common in enterprise networks, data centers, or campus networks where you need reliable, high-speed fiber links over shorter distances.

Compatibility:

• Works with Cisco switches and routers that have compatible SFP slots, and it may also be compatible with other vendors’ devices, but it’s ideal to use with Cisco equipment for full functionality and support.

The “MMD” in the part number stands for “Multimode Distance” and indicates that this module is optimized for multimode fiber connections.
