X22 - Bi-directional BNC TTL to Fiber-optic Converter

The X22 is a compact bidirectional TTL to fiber-optic converter designed to efficiently convert digital voltage signals to and from fiber-optic signals. With its small form factor, the X22 is independently powered from an isolated power supply, offering high voltage isolation between TTL input and outputs when used in pairs.

Featuring a configurable polarity of conversion with two physical switches for each direction, the X22 provides flexibility in its operation. The TTL inputs can be high impedance or 50 ohm, settable with an internal jumper specified during the ordering process. Additionally, the fiber-optic connectors can be either ST type or Versatile Link style, also specified upon ordering.

Built with robust components, the X22 ensures reliable performance under various operating conditions. It is ideal for a variety of applications, including converting UART communication signals such as RS232 to and from fiber optics using standard baud rates, trigger and logic-level signal delivery in large distributed systems, high voltage digital I/O isolation, and general-purpose logic signal conversion.

With optional DIN rail mounting and a compact stainless-steel chassis, the X22 is a versatile choice for various scenarios. For unidirectional TTL to fiber applications that can drive 30mA, consider the TF1 as a simpler alternative. To "fan-out" the signal to multiple fiber outputs, the X14 device is recommended.
