ETL Systems StingRay SRY-TX-B2-925 Outdoor RF over Fiber Transmitter

The ETL Systems StingRay SRY-TX-B2-925 is an IP65 outdoor RF over fiber transmitter covering 50–2450 MHz, with a 1310 nm optical output and switchable LNB power.

Designed for satellite RF signal transport over single-mode fiber, the SRY-TX-B2-925 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.
