GLC-SX-MMD 1000BASE-SX short wavelength with DOM

GLC-SX-MMD is an SFP networking equipment used to connect your switches and router to the network through a fiber optic cable. Basically, it is designed to work with a fiber optic cable known as Multimode, which is used to transfer data over narrow distances.

Specifically, it is manufactured to use with multimode fiber, a type of cable used in local networks.

Commonly, it functions at the IEEE 802.3z 100BASE-SX standard, which is considered a common standard for networking for gigabit network connections.

It works with 50 µm multimode fiber up to 550 meters. For older 62.5 µm fiber (like FDDI-grade), it works at a distance of up to 220 meters. With special, laser-optimized 50 µm fiber, it can reach up to 1 kilometer.

Uses an 850-nanometer wavelength, suitable for short-range communication. It has a flexible operating temperature range, which means it can work in different environmental conditions. Supports DOM (Digital Optical Monitoring) for a seamless tracking of the system’s activity.

It uses a dual LC/PC connector, a common type of connector for fiber optic cables.

SFP Port Cabling Specifications

^*A mode-conditioning patch cord, as specified by the IEEE standard, is required regardless of the span length. Note how the mode conditioning patch cord for 62.5-μm fibers has a different specification from the mode-conditioning patch cord for 50-μm fibers.

^**ITU-T G.652 SMF as specified by the IEEE 802.3z standard.

^***Specified at transmission wavelength.
