Product Features
Technical Overview
The SR-100-ST20U operates at Fast Ethernet speeds (100 Mbps) and supports network technologies including 100Base-TX for copper and 100Base-BX/BX-D for fiber. It uses a 9/125 µm core/cladding specification, which is standard for single-mode fiber, ensuring compatibility with common infrastructure.
Advanced features such as Link Pass-Through, Far-End Fault detection, and Auto-MDIX enhance reliability and simplify deployment by automatically adjusting for straight-through or crossover cable connections on the copper side.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

FAQ
What does this media converter do?
The Perle SR-100-ST20U converts Fast Ethernet signals from copper twisted-pair cabling (100Base-TX) to single-mode fiber optic signals (100Base-BX or 100Base-BX-D). This allows you to extend network connections up to 20 kilometers while leveraging fiber's immunity to electromagnetic interference.
What types of connectors does it have?
It has two ports: one RJ-45 port for copper Ethernet connections and one ST simplex port for fiber optic cabling. The ST port uses a simplex connector, which is common for single-mode fiber installations requiring one fiber strand per direction.
What is the maximum distance supported?
This converter supports fiber optic distances up to 20 kilometers (approximately 12.43 miles) when using single-mode fiber with 9/125 µm core/cladding. This extends far beyond typical copper Ethernet limits, making it suitable for long-range network links.
What wavelengths does the fiber port support?
The fiber port supports wavelengths of 1310 nm and 1550 nm. These are standard wavelengths for single-mode fiber optics, allowing compatibility with a wide range of fiber infrastructure and transceivers in networking environments.
How is this converter powered?
It is powered by an AC adapter. The design also includes triple power input options, such as dual terminal block power connectors and T-Bus, providing redundancy and flexibility for different power sources in industrial or rack-mounted setups.
Is this unit rack-mountable?
Yes, the SR-100-ST20U has a rail-mountable form factor, allowing it to be installed on standard DIN rails or equipment racks. This makes it ideal for organized deployments in data centers, network closets, or industrial control panels.
