User Manual
FAQ
What is the primary function of the LBH100AE-ST media converter?
The Black Box LBH100AE-ST serves as a Fast Ethernet media converter that bridges copper and fiber network segments. It converts signals between two RJ45 copper ports and one ST multimode fiber port while also functioning as a basic 2-port switch between the RJ45 connections. This dual functionality allows network expansion beyond copper distance limitations while maintaining switching capabilities.
What types of fiber connections does this converter support?
This specific model features one duplex ST connector for multimode fiber connections. The converter operates at 850 nm wavelength and supports standard multimode fiber optic cabling. While this unit has an ST interface, the LBH100 series is available with various fiber connector types including SC, MT-RJ, and LC to match different infrastructure requirements.
What is the maximum distance supported by the fiber port?
The LBH100AE-ST supports data transmission up to 2 kilometers (approximately 1.24 miles) when using multimode fiber optic cabling. This extended reach capability makes it suitable for connecting network segments across buildings or throughout large facilities where copper Ethernet distance limitations would otherwise require additional networking equipment.
How many devices can connect to this media converter?
The converter provides three network ports total: two RJ45 copper ports and one ST fiber port. The two RJ45 ports function as a basic switch, allowing multiple copper-based devices to connect and communicate with each other. The fiber port connects to fiber optic network infrastructure, enabling the converter to bridge between copper and fiber segments while providing local switching between connected copper devices.
What mounting options are available for installation?
The LBH100AE-ST supports multiple mounting configurations including rack mounting, DIN rail mounting, wall mounting, desktop placement, and panel mounting. For rack installations, an optional rackmount tray is available separately that can hold up to 16 units. The compact dimensions of 3.5" x 3" x 1" make it suitable for space-constrained environments across various deployment scenarios.
What power requirements does this media converter have?
The converter uses an external power supply and is available with either 115-VAC or 240-VAC power options. Spare power supplies are also available separately for redundancy or replacement needs. The device operates within a temperature range of 32° to 104°F (0° to 40°C), making it suitable for most indoor environments including temperature-controlled and industrial settings.
