The Firecomms Crimpless Connectors are for use with a standard 1mm core with 2.2mm plastic fiber optic (POF) sheath. This series of connectors has been designed for ease of use. The simple locking function secures the POF cable securely to the connector without the need for a crimp tool. This flexibility allows you to reduce the amount of work required and the associated costs. They are compatible with RedLink® or Versatile Link transmitters and receivers.
