Silent Knight SK-FML Fiber Card (New)

The SK-FML and SK-FSL are plug-in fiber loop modules. These work as one channel to transmit or receive communications with the SK-NIC ARCNET communication circuit.

The SK-FML (Fiber-optic Multi-Mode) module allows multimode fiber to connect network nodes. It features ST-style connectors with a maximum attenuation of 8db with 62.5/125 micron cable. The SK-FSL (Fiber-optic Single-Mode) module allows single mode fiber to connect network nodes. It features LC-style connectors with a maximum attenuation of 30db with 9/125 micron cable.
Each fiber loop module can Transmit (TX) or Receive (RX) on a fiber-optic cable connecting to the SK-NIC (Network Interface Card). Up to two fiber loop cards can be added to the SKNIC, and both cards may be combined in the same configuration.
The SK-FSL/SK-FML and SK-NIC enables a common communications and annunciation link to be created between up to 17 panels. A designated panel is configured as the communicator for all panels in the link for convenient single-point communications. Note: The SK-NIC provides a common communications link for 6700, 6808, 6820 and 6820EVS. However, they cannot be linked together for peer-to-peer networking.
