Ring/multidrop fibre converter, RS232
  • 1 xRS-232 port 300 bit/s - 250 kbit/s
  • Overview
  • Specifications
  • The ODW-720-F2 has been designed to allow the use of fibre optic cables on RS-232 networks. The design allows the use of a range of Westermo verified SFP (Small Form Pluggable) transceivers which can provide solutions with, for example, only a single fibre or distances up to 120 km.

    Both multidrop networks and redundant rings can be formed using a mixture of transceiver types.

    This unit has been designed for industrial use where the requirement is for a long and reliable service life, in a harsh environment. To ensure this reliable operation we manufacture using the highest quality components.

    The ODW-720 draws on Westermo's many years of knowledge of serial protocols and can even transmit a second data channel if necessary.

    Large ring networks can be created to provide network resilience to guarantee system functionality, even if a cable is damaged. The ring recovery time ensures that the network devices are not aware of the failure. The fault contact provides a method to communicate network failures.

    Numerous fibre configuration options

    • Up to 120 km distance
    • BiDi support (single fibre)
    • Multimode and singlemode SFPs
