This broadcast-grade system is primarily used where uncompressed, zero-latency high-definition video needs to be transported over long distances (typically 10km via Single-Mode Fiber) without degradation or electromagnetic interference.
-
Outside Broadcasting (OB Vans) & Mobile Production: Allows production trucks to interface directly with field cameras, field monitors, and production switchers located kilometers away.
-
Live Event & Concert Production: Transmits multi-camera setups from the stage to the front-of-house (FOH) or broadcast control room while simultaneously sending return feeds (e.g., director monitors, teleprompter feeds, or return program video) back to the stage.
-
TV Studio & Remote Production (REMI): Connects remote studios, newsrooms, or control rooms across different floors, buildings, or campus facilities.
-
4K / UHD Video Transmission: Because it features 8 individual 3G-SDI channels, it can be combined to transmit up to two independent 4K/UHD streams at 60fps (using Quadrant 4-link 3G-SDI mapping) or up to four 4K streams at 30fps.
- Command & Control Centers / Military: Used in secure environments for flicker-free, real-time uncompressed video monitoring over vast distances.
Features:
- Support for 4/8 Ch 2 Way (Bidi) independent 3G/HD/SD-SDI channels over 1 Core Single-mode Fiber 10+Km, Pass All Pathological Patterns.
- Complait with SMPTE Standards: SMPTE ST 425-3, ST 425-5, 259M-2006, 292-2006, 424M-2006, SMPTE 305M-2005, 310M-2004, 344M-2000
- BMD SDI Devices Compatible
- CWDM optical multiplexing technology, Each SDI signal has its own laser and its beeing convert to the different optical wavelength.
- Each Channel supports SMPTE standard of SDTV (143-540Mbps), HDTV (1.485Gbps) and HDTV (3Gbps, 1080p60). Each channel SDI individually re-clocked input and individually re-clocked SDI output
- Embedded audio / data support for each channel.
- LED indicators for channel activity and power
- SMPTE 3K93C Connector Optional
