High-Performance Camera Back Fiber Link Solution with Advanced Lanc Extension
Transwan EFP Fiber System BY-EFP-BMDLANC-231 is a professional-grade, multi-channel camera back fiber link solution designed for Electronic Field Production (EFP), live broadcasting, and studio environments. Connected via a single SMPTE 304M Hybrid Optical Cable, this system delivers uncompressed Ultra-HD video, return video, intercom, data, and remote control capabilities while simultaneously providing power from the Base Station to the Camera Adapter.
Highlight Feature: Long-Distance LANC Remote Control over Fiber
Eliminate the distance limitations of standard camera control cables. The AK-20240104 features a dedicated, bidirectional LANC Remote-to-Fiber conversion pipeline. By encoding the LANC protocol directly into the optical stream, studio operators can control zoom, focus, iris, and camera menus flawlessly from hundreds of meters away at the Base Station with zero latency, just as if the remote were plugged directly into the camera body.
System Architecture & Key Interfaces
1. Camera Adapter (Camera-Back Unit)
Engineered to mount directly to professional cameras (featuring a V-mount interface), the compact Camera Adapter consolidates all field signals into a single fiber link. To accommodate different rigging setups, it features a unique 90-degree rotatable SMPTE 304M Hybrid Connector.
