Compact Gigabit fiber converter

The StarTech MCMGBSCMM055 converts a Gigabit Ethernet link to multimode SC fiber and back, reaching 550m at 850nm wavelength. It supports IEEE 802.3z 1000BASE-SX and 1000BASE-T standards with full-duplex flow control. The unit includes a universal AC adapter and ships new with a quick-start guide.

Wall-mountable metal enclosure

The converter measures 1.00" x 3.80" x 2.80" and weighs .44 lb, fitting tight cabinet spaces while the metal chassis aids heat dissipation. A single SC duplex port handles fiber and an RJ-45 port handles copper, each with dedicated link and activity LEDs. Power draw is 5 W from the supplied 100-240 VAC adapter, and operating temperature spans 0 to 50°C.

Extends copper runs beyond 100m

This device replaces a direct copper patch when the link exceeds the standard twisted-pair distance limit, letting you bridge buildings or floors over existing multimode fiber. It adds VLAN pass-through and link-fault-pass-through so upstream switches see the true link state. The jump is worth it when you need a powered, managed media conversion point rather than a passive patch panel.

Questions about this item

What distance does the 1000BASE-SX interface support over multi-mode fiber?

The 1000BASE-SX standard on this converter reaches 550m over multi-mode fiber at 850nm wavelength.

What physical space and mounting options does the converter need?

It measures 1.00" x 3.80" x 2.80", weighs .44 lb, and includes a wall-mountable compact design.

How do I power and connect the unit, and what step is often missed?

Plug the included universal AC adapter (100-240V AC in, 5V DC 2.6A out) into the center-positive jack, connect SC fiber and RJ45 copper, then verify the 1000 Link LED lights solid for a valid gigabit link.
