SK-FML SILENT KNIGHT BY HONEYWELL Multi-mode Fiber Daughter card for network connection
The Honeywell SK-FML (Fiber-Optic Multi-Mode) and SK-FSL (Fiber-Optic Single-Mode) are plug-in fiber loop modules. These work as one channel to transmit or receive communications with the Honeywell Silent Knight SK-NIC (Network Interface Card) ARCNET communication circuit.
The SK-FML module allows multimode fiber to connect network nodes. It features ST-style connectors with a maximum attenuation of 8db with 62.5/125 micrometer cable. The SK-FSL module allows single mode fiber to connect network nodes. It features LC-style connectors with a maximum attenuation of 30db with 9/125 micrometer cable.
Each fiber loop module can Transmit (TX) or Receive (RX) fiber-optic cable connecting to the SK-NIC. Up to two fiber loop cards can be added to the SK-NIC and both cards may be combined in the same configuration.
Both modules are listed per ANSI/UL Standard 864 9th edition.
Use these two modules with the SK-NIC to create a common communications and annunciation link on a fiber-optic network of up to 17 panels. A designated panel is configured as the communicator for all panels in the link for convenient single-point communications. Note that panels can also be connected in this way using copper wire.
