ETL Systems StingRay SRY-G1S-RY-176 1PPS–1MPPS & IRIG-B Fiber Optic Receiver

ETL Systems StingRay SRY-G1S-RY-176 1PPS–1MPPS & IRIG-B Fiber Optic Receiver

The ETL Systems StingRay SRY-G1S-RY-176 recovers 1PPS–1MPPS pulse signals and IRIG-B DCLS TTL timing signals from an incoming optical signal. It supports timing distribution links up to 10 km when paired with a compatible transmitter and an appropriate single-mode fiber link.

The receiver accepts optical wavelengths from 1100–1650 nm, optimized for 1310 nm and 1550 nm, and provides a nominal 5 V peak TTL signal through a 50 Ω SMA or BNC interface. FC/APC and SC/APC optical connector options support different installation requirements.

Its compact, hot-swappable module occupies one slot in a compatible GENUS 1U chassis. Chassis-based local and remote monitoring provides access to output TTL frequency, optical input level, and module temperature through the front-panel interface, Ethernet, SNMP, and a web browser.

The module is designed to work with the SRY-G1S-TY-175 and SRY-G2S-TY-323 transmitters.

Key Features

• Recovers pulse and IRIG-B DCLS TTL timing signals from optical fiber.

• Low jitter and fast rise/fall times.

• Hot-swappable module for compatible GENUS chassis.

• Local and remote monitoring of output TTL frequency, optical input level, and module temperature.

• Compatible with SRY-G1S-TY-175 and SRY-G2S-TY-323 transmitters.

• Indoor operation; outdoor use only within a compatible ETL ODU enclosure.

Compatible transmitter, GENUS chassis, and fiber cables are sold separately unless included in the quoted configuration. This module recovers a transported timing signal; it does not generate timing independently. IRIG-B support is for DCLS TTL signals.
