Clear-com HLI-FBS Fiber Interface Module

Clear-com  HelixNet HLI-FBS fiber linking interface is a dual port Ethernet switch interface module with 100MB SFP connectors for the HMS-4X** main station. The HLI-FBS 100MB SFP connectors can be populated with compatible single or multi-mode fiber transceivers.


HLI-FBS allows access to HelixNet’s internal network for direct fiber connected HMS-4X** linking. LQ® Series linking and user station network connection, system control and monitoring from the browser-based Core Configuration Manager™ (CCM*) can be established with the use of third-party 100MB network peripherals. HLI-FBS can be added to any HMS-4X** main station with an available option slot.

*CCM requires HLI-ET2
**HMS-4X is a legacy product as of 2022
