ETL Systems StingRay SRY-TX-B2-403 Broadband RF over Fiber Transmitter

ETL Systems StingRay SRY-TX-B2-403 Broadband RF over Fiber Transmitter

The ETL Systems StingRay SRY-TX-B2-403 is a standalone broadband RF over fiber transmitter with a 1310 nm optical output, RF monitoring port and switchable LNB power.

Designed for single-mode fiber links, the SRY-TX-B2-403 converts broadband RF signals into an optical signal using a DFB laser with an optical isolator. Its compact EMC-sealed housing supports tapped-screw and through-hole mounting. Local DIP switches control LNB power, voltage, 22 kHz tone and gain mode, while indicator lights show power and module status. Pair it with the SRY-RX-B2-404 receiver for a complete RF over fiber link.
