Product Features
Technical Overview
Technically, the LBH100A-P-ST operates as a transparent media converter, supporting data rates up to 100 Mbps. It features two 10/100Base-TX RJ45 ports for copper connections and one duplex ST port for multimode fiber with a 1300 nm wavelength. The device handles conversion between electrical signals on twisted pair and optical signals on fiber, maintaining signal integrity across a maximum supported distance of 2 kilometers.
Power is supplied via an included 100-240 VAC power adapter, ensuring compatibility with standard electrical outlets globally. The converter uses store-and-forward switching to prevent packet errors during media translation, and it supports auto-negotiation on copper ports for seamless integration with existing network equipment.

FAQ
What does this media converter do?
The Black Box LBH100A-P-ST converts network signals between copper Ethernet (10/100Base-TX) and multimode fiber optic (100Base-X). It allows you to extend your network beyond the 100-meter limit of copper cabling by using fiber for distances up to 2 km, while maintaining Fast Ethernet speeds of up to 100 Mbps.
What types of ports does it have?
This converter has three ports: two RJ45 ports for connecting to copper Ethernet devices like switches or computers, and one duplex ST port for connecting to multimode fiber optic cables. The ST port uses a bayonet-style connector commonly found in fiber networking for secure connections.
What is the maximum distance supported on fiber?
It supports a maximum distance of 2 kilometers (approximately 1.24 miles) when using multi-mode fiber optic cables. This makes it suitable for linking network segments across buildings or campuses without signal degradation, far exceeding the typical 100-meter range of copper Ethernet.
How is this device powered?
The converter is powered by an included 100-240 VAC power supply, which plugs into standard electrical outlets. This external power method allows for easy installation without requiring internal power slots, and the wide voltage range ensures compatibility with power systems in North America and internationally.
Can this converter be rack-mounted?
Yes, it features an external, rack-mountable form factor. You can mount it on a standard equipment rack using appropriate brackets or shelves, making it ideal for organized installations in server rooms, telecom closets, or industrial control panels where space optimization is important.
What type of fiber optic cable is compatible?
It is compatible with multi-mode fiber optic cables that use a 1300 nm wavelength and ST connectors. Multi-mode fiber is commonly used for shorter to medium-distance runs like within buildings or campuses, and the ST duplex port ensures proper alignment for reliable data transmission over fiber.
