FAQ
What does this media converter actually convert?
The Perle SR-100-ST40-XT converts Fast Ethernet (100 Mbps) signals between copper twisted pair (RJ-45) and single-mode fiber optic (ST duplex) connections. It takes electrical signals from standard Ethernet cabling and converts them to optical signals for transmission over fiber, then converts them back to electrical signals at the receiving end. This allows network segments to extend far beyond the 100-meter limitation of copper cabling.
What is the maximum distance this converter can support?
This media converter supports transmission distances up to 40 kilometers (approximately 24.85 miles) when used with single-mode fiber optic cable. This substantial reach makes it ideal for connecting network segments across campuses, between buildings, or to remote equipment locations where traditional copper Ethernet would require multiple repeaters or signal boosters to maintain connectivity.
What type of fiber optic connectors does this unit use?
The converter features two ST duplex fiber optic ports. ST connectors are bayonet-style connectors commonly used in single-mode fiber installations. The duplex configuration means each port accommodates two fibers (one for transmit, one for receive) in a single connector, simplifying cable management compared to separate simplex connections while ensuring proper polarity for bidirectional communication.
Can this converter operate in extreme temperatures?
Yes, the SR-100-ST40-XT is designed for extended temperature operation from -40°C to +75°C (-40°F to +167°F). This wide operating range makes it suitable for industrial environments, outdoor installations, and other challenging locations where commercial-grade networking equipment might fail due to temperature extremes. The robust construction ensures reliable performance in manufacturing facilities, transportation systems, and utility networks.
How is this media converter powered?
The converter includes multiple power input options for deployment flexibility. It supports power via an AC adapter as well as dual terminal block power connectors and T-Bus compatibility. This triple power input design provides redundancy options and makes the unit adaptable to different installation scenarios, whether in standard network racks with AC power or industrial panels with terminal block power distribution systems.
What advanced features does this converter include?
The SR-100-ST40-XT includes several advanced management features: Link Pass-Through maintains connectivity if power is lost to the unit, Far-End Fault detection identifies problems at the remote end of the fiber link, and Auto-MDIX automatically configures the correct pinout for straight-through or crossover Ethernet cables. These features simplify installation, enhance network reliability, and provide clear status indicators for troubleshooting.
