Key Features

  • Multiple mount shapes

    Round mount with central screw or H-shaped (rectangular) mount with two screws — H-shape uses the SC simplex/duplex footprint for easy panel-mount installation.

  • Zinc-alloy metal body

    Metal-housing variants use a zinc-alloy coupling body for long life. Plastic-housing variants follow the SC footprint and use colour coding: SM in blue, MM in beige (for the screw-mount range).

  • Bayonet locking

    Standard ST bayonet-style locking — quick connect/disconnect for service work.

  • Ceramic precision sleeve

    High-precision Zirconia ceramic sleeve in all variants.

  • PVC dust caps

    Pluggable PVC dust caps: yellow for singlemode UPC (red on request), black for multimode.

  • Snap-in or threaded mounting

    Threaded with nuts or snap-in coupling — easy panel-mount installation.

Available Variants

  • Simplex (STsx)
  • Duplex (STdx)

  • Plastic
  • Round mount
  • H-shaped (SC footprint)
  • Bayonet locking
