The Clear-Com HelixNet HLI-FBS Fiber Interface Card is a high-performance module designed to dramatically extend the reach and robustness of a HelixNet digital intercom matrix using fiber optic cabling. This card installs directly into a HelixNet Main Station or compatible frame, adding one or more fiber optic ports to the system. Its primary function is to convert the digital intercom data, including all audio channels, signaling, and control information, into optical signals for transmission over single-mode or multi-mode fiber. This enables virtually lossless communication between separate HelixNet systems or remote stations over distances of many kilometers, far exceeding the limitations of standard copper Ethernet cabling.

The use of fiber optic technology brings critical advantages to large-scale or distributed production facilities. It provides complete immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), which is essential in environments crowded with electrical equipment, such as broadcast trucks, stadiums, and industrial plants. Fiber also eliminates ground loop issues that can cause hum in audio systems. The HLI-FBS card typically supports hot-swappable Small Form-factor Pluggable (SFP) transceivers, allowing system integrators to choose the appropriate fiber type and connector (LC is common) for the required transmission distance and existing infrastructure. This flexibility makes it ideal for linking buildings on a campus, connecting a main broadcast compound to remote camera positions, or creating a redundant network backbone.

Integration into the HelixNet ecosystem is seamless. Once installed, the fiber links appear as logical connections within the system's configuration software, allowing audio channels and partylines to be routed between geographically separated main stations as if they were in the same rack. This capability is fundamental for creating a unified, site-wide communication network. For large events or permanent installations requiring reliable, long-distance, and high-bandwidth intercom links, the HelixNet HLI-FBS Fiber Card is an essential component that ensures crystal-clear, low-latency communication across the entire operational area, future-proofing the system and providing unparalleled flexibility in system design.
