StingRay 200 1PPS to 1MPPS and IRIG-B (DCLS TTL) Transmit Fibre Converter


  • Description

    Model SRY-TX-Y-285, 200 series StingRay RF Over Fibre is an optical transmitter module for 1PPS up to 1MPPS, and IRIG-B (DCLS TTL) over fibre, providing compact fibre links up to 10 Km for timing and reference applications.

    It is a TRANSMIT module that converts 1PPS to 1MPPS and IRIG-B (DCLS TTL) signal to optical, with a monitor port to measure signal levels.

    It is designed to be housed in a 200 series indoor chassis and works with ETL's receive module SRY-RX-Y-286.

    The StingRay RF Over Fibre module is available in a variety of RF and optical connector types. See below for related modules and chassis, view the datasheet for full technical specifications.

  • Fibre Connectors

    Optical fibre connectors are used to terminate the end of an optical fibre cable and enables quick connection.

    Angle Polished Connectors
    All of the connectors we offer are APC connectors (Angled Physical Contact). APC connectors are used as they provide extremely reliable way of achieving the high return losses essential in RF systems.
    APC connectors have the fibre end face polished at an 8-degree angle to prevent light that reflects from the interface from traveling back up the fibre.

    Due to the angle of the connector, the reflected light does not stay in the fibre core/cladding but instead leaks out into the cladding. APC connector return loss is around -60 dB.

    We offer 2 optical fibre connector types that offer low loss and create an extremely reliable connection:


    FC/APC (Angled ferrule connector / fibre connector).
    Ferrule diameter: 2.5 mm
    Coupling type: screw


    SC/APC (Angled subscriber connector / square connector / standard connector).
    Ferrule diameter: 2.5 mm
    Coupling type: Snap (push-pull coupling)

  • Typical Applications
    • Mission critical PPS distribution for communication systems, satellite earth stations, test facilities and engineering.
    • Small quantity links such as tactical HQ
    • A resilient solution for satellite teleports and other facilities with transmission distances up to 10km
