FAQ

What types of media does this converter support?

This converter supports twisted pair copper via its RJ-45 port and optical fiber via its ST duplex port. It is designed for single-mode fiber, which allows longer distance transmissions compared to multimode fiber, making it suitable for extended network segments.

What is the maximum distance this media converter can support?

The maximum supported distance is 28 kilometers (approximately 17.40 miles) when using single-mode fiber. This extended reach is ideal for connecting remote buildings or long-haul network links without signal loss, leveraging fiber's low attenuation characteristics.

What Ethernet speeds does this converter handle?

It handles Fast Ethernet speeds, supporting 10/100Base-TX over twisted pair copper and 1000Base-FX over fiber. This means data transfer rates up to 100 Mbps on the copper side, suitable for standard office or industrial network traffic without bottlenecks.

How can this converter be mounted or installed?

The converter offers multiple mounting options: it is rack-mountable for standard 19-inch racks, wall mountable with appropriate hardware, standalone for desktop use, and rail-mountable for industrial settings. This flexibility allows installation in data centers, network closets, or on-site locations as needed.

Is this product TAA compliant and where is it made?

Yes, this product is TAA compliant, meaning it meets the Trade Agreements Act requirements for U.S. federal government procurement. It is manufactured in the United States, ensuring eligibility for contracts that mandate domestic or designated country sourcing.

What power source does this media converter require?

It requires an external power supply for operation. The converter does not support Power over Ethernet (PoE) or other integrated power methods, so a dedicated power adapter is necessary, typically included or specified for reliable performance in various deployment scenarios.
