ETL Systems StingRay SRY-TX-L1-401 L-Band RF over Fiber Transmitter

ETL Systems StingRay SRY-TX-L1-401 L-Band RF over Fiber Transmitter

The ETL Systems StingRay SRY-TX-L1-401 is a standalone 850–2450 MHz L-band RF over fiber transmitter with a 1310 nm optical output, RF monitoring port and switchable LNB power.

Designed for satellite L-band signal transport over single-mode fiber, the SRY-TX-L1-401 uses a DFB laser with an optical isolator. Its compact EMC-sealed housing supports tapped-screw and through-hole mounting. Internal DIP switches select LNB power, voltage, 22 kHz tone and automatic or fixed-gain operation. Pair it with the SRY-RX-L1-402 receiver for a complete RF over fiber link.
