ETL Systems StingRay SRY-TX-Y-481 Standalone 10 MHz RF over Fiber Transmitter

ETL Systems StingRay SRY-TX-Y-481 Standalone 10 MHz RF over Fiber Transmitter

The ETL Systems StingRay SRY-TX-Y-481 converts a supplied 10 MHz reference signal into a 1310 nm optical signal for transport over single-mode fiber. Its compact EMC-sealed standalone housing supports reference distribution in satellite communications and RF systems.

The transmitter accepts RF input levels from 0 to +15 dBm and features a DFB laser with a two-stage optical isolator. An RF monitor port supports signal checks, while local power and status indicators assist operation. Monitoring includes laser optical output power, amplifier status, and module temperature.

Tapped screw and through-hole mounting options support installation within equipment assemblies. The module operates from 12 V DC and supports single or dual redundant power arrangements.
