StingRay100 CWDM 8-way Multiplexer / Demultiplexer for Fibre Optic Link / IFL


  • Description

    Model SRY-OCM-08-545-47, 100 series 8-way multiplexer / demultiplexer RF over Fibre module for a CWDM system. This module combines and separates optical signals for 50 km transmission distance.

    It is designed to be housed in a 100 series indoor chassis.

    The StingRay RF over Fibre module is available in 2 optical connector types. See below for related chassis.

  • CWDM System

    The StingRay CWDM system comprises of transmit RF over fibre modules and a multiplexer module to combine up to 8 wavelengths on to a single fibre cable at the transmit end.

    A demultiplexer module and receive RF over fibre modules are then used at the receive end to split the separate wavelengths. The StingRay series CWDM range of RF over fibre modules can convert L-band (850 MHz - 2450 MHz) and Broadband (50 MHz - 2450 MHz) frequencies up to 50km transmission distances.

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