Mini-type 3G-SDI to Fiber Converter with Tally & Reverse RS485
Overview
LNK-M3G-1V Series is a compact and high-performance 3G/HD-SDI fiber
optic converter, designed
for professional broadcast and video transmission applications. It
supports:
- 1 channel 3G/HD-SDI video (with embedded audio)
- Tally signal (for camera control and intercom)
- Reverse RS485 data (for bidirectional communication)
All signals are transmitted over a single fiber optic cable,
ensuring long-distance, low-latency, and
interference-free signal delivery. A local 3G/HD-SDI loop output
allows real-time monitoring for system
verification.
The E-link 3G/HD-SDI Video over Fiber Converters set includes one
transmitter and one receiver,
fully compatible with 1080p and other standard 3G/HD-SDI video
formats.
Ideal for live production, broadcast, and AV systems, this
converter provides a reliable and cost-effective
solution for high-quality video over fiber.
