Media converter function

The MPT-G21SC converts Gigabit Ethernet signals between copper and multimode fibre. It accepts 1000Base-T on an RJ-45 port and 1000Base-SX on an SC port. The module operates at an 805 nm wavelength over 50/125 µm or 62.5/125 µm fibre. Maximum link distance is 1804 ft.

Fit for copper-to-fibre links

This unit suits networks that need to extend a copper run over multimode fibre within the stated distance. It is not for single-mode fibre deployments, nor for links that exceed the 1804 ft reach. Buyers needing higher speeds or different connector types should look at other models.

Dual-port interface

One RJ-45 port and one SC duplex port provide the physical connection points for the conversion. The transceiver fits standard SFP slots and requires no additional configuration for the supported media types. Dimensions are 1.0' height, 2.8' width and 3.7' depth.

Questions about this item

How do I install the MPT-G21SC and what step is often missed?

Insert the transceiver into an SFP slot until it clicks, connect RJ-45 Cat. 5/5e to the copper port and SC duplex fibre to the optical port, then verify the link LEDs on both sides — the step often missed is matching the 805 nm wavelength on both ends.

What maintenance or replacement will the MPT-G21SC need later?

The transceiver itself has no moving parts or user-replaceable items; plan to re-inspect and clean the SC connectors with a fibre scope and lint-free wipes whenever cables are moved, and replace the unit only if link errors persist after cleaning.

What limit appears first on the MPT-G21SC during sustained use?

The 1804 ft multimode fibre distance ceiling is the first hard limit — links beyond that length will lose signal integrity regardless of cable quality or traffic load.
