E-link Mini HD-SDI Fiber Converter with Tally & RS485 Loop Out
E-link Mini HD-SDI Fiber Converter with Tally & RS485 Loop Out
Overview
The LNK-MHD-1V Series Mini-type HD-SDI to Fiber Converter by E-link is a compact and
industrial-grade solution designed for transmitting uncompressed HD-SDI video (with
embedded audio), Tally signals, and reverse RS485 data over a single optical fiber.
Supporting video resolutions up to 1080i and a data rate of up to 1.485Gbps, this converter
features automatic cable equalization, loop-out monitoring, and robust performance across
extended distances—up to 20km on single-mode fiber. Engineered for demanding
environments, it offers wide temperature tolerance (-20℃ to +70℃), LED status indicators,
hot-swappable installation, and compatibility with SDI camera systems. Ideal for broadcast,
live events, and studio applications requiring reliable, real-time video transmission over fiber.
