Product Features
Technical Overview
The LMC270A-MM-ST operates as a transparent media converter, handling Ethernet, Fast Ethernet, and Gigabit Ethernet protocols without configuration. It supports 10/100Base-TX on the copper side and 1000Base-FX on the fiber side, ensuring seamless conversion between these standards. The multi-mode fiber compatibility with ST connectors provides a reliable optical interface for short to medium-distance runs.
With a maximum distance of 20 kilometers over fiber, this converter effectively extends network segments beyond the 100-meter limit of copper cabling. The compact dimensions of 4.30" x 1" x 2.80" (109.22 mm x 25.40 mm x 71.12 mm) and lightweight design at 226.8 grams allow for dense installations without excessive space consumption.
