1U 8-Ch SD/HD/3G-SDI Fiber CWDM Extender Broadcast-Grade up to 120Km
Overview
The LNK-SDI-8V Series delivers reliable 8-channel SD/HD/3G-SDI video transmission over a single
optical fiber using advanced CWDM technology. Supporting resolutions up to 1080p60, it ensures
uncompressed broadcast-quality delivery with automatic equalization and re-clocking. With reverse
RS-485 data, hot-swappable design, and rack-mount form factor, it is ideal for professional broadcasting,
live event production, and mission-critical video transport over distances up to 120Km.
Features
8-Channel Video Transport: Simultaneous SD/HD/3G-SDI over single fiber.
CWDM Technology: Efficient multiplexing for long-distance high-bandwidth links.
Signal Integrity: Auto equalization and re-clocking for stable transmission.
Uncompressed Quality: Broadcast-grade digital video up to 1080p60.
Reverse RS-485: Built-in return data channel for camera or control systems.
Fiber Range: From 10Km up to 120Km over simplex LC fiber.
Rack-Mount Design: 1U chassis with LED status monitoring.
Rugged & Reliable: Operates from -20°C to +70°C, MTBF >100,000h.
