The MC102 product line encompasses copper-to-fiber and fiber-to-fiber conversion units. On all of these converters, the fiber port(s) allow a choice of multimode or single mode fiber, single fiber operation, different wavelengths and power levels.

The MC102FRC is a 100BaseTX to 100BaseFX repeater, targeted for applications requiring long frames (more than 1522 bytes), such as those used by MPLS encapsulation. The MC102FRC also provides an Automatic Link Integrity (ALI) feature, which automatically shuts down the copper link in case of fiber link failure.
