Product Overview

The Comtech Mini Transmitter is designed for environments where space, performance, and energy efficiency are critical. It receives analog or digital RF signals and converts them into optical signals using advanced laser technology. The optical output can then be transmitted over single-mode fiber to distant nodes, optical receivers, or subscriber endpoints with virtually no signal degradation.

Compact, durable, and easy to install, this transmitter is ideal for distributing RF signals in residential, commercial, or institutional settings. Its compatibility with standard wavelengths (1310 nm and 1550 nm) allows seamless integration into most existing fiber networks.
