• Can the LGCell use 50µm/125µm multimode optical fiber?
The LGCell is designed for use with 62.5µm/125µm fiber. Use of 50µm/125µm
fiber results in higher optical losses and degraded performance.
• How much space does the Main Hub and Expansion Hub use in a 19 in. rack?
Both units use 1U of rack space.
• Can I connect the LGCell alarms to a base station?
Yes. Use the major alarm contacts only. The base station supplies the return
ground and voltage.
