ETL Systems StingRay SRY-TX-L1-923 Outdoor L-Band RF over Fiber Transmitter

ETL Systems StingRay SRY-TX-L1-923 Outdoor L-Band RF over Fiber Transmitter

The ETL Systems StingRay SRY-TX-L1-923 is an IP65 outdoor L-band RF over fiber transmitter covering 850–2450 MHz, with a 1310 nm optical output and switchable LNB power.

Designed for satellite L-band signal transport over single-mode fiber, the SRY-TX-L1-923 houses one optical transmitter in a compact weatherproof enclosure. Its DFB laser incorporates a two-stage optical isolator for improved performance. The unit supports pole or wall mounting, automatic or fixed-gain operation, and 13/18 VDC LNB powering with a selectable 22 kHz tone. External power supplies support dual redundant operation.
