Description:
HZT-SDI-12G-4V2V1E-SM001 is a professional-grade, high-density fiber optic media converter designed for broadcast, live production, and high-performance video distribution applications. It provides bidirectional conversion between four (4) channels of 12G-SDI video inputs and two (2) channels of return 12G-SDI video over a single fiber optic link, simultaneously supporting a 1Gigabit Ethernet data channel. This integrated solution dramatically simplifies cabling, extends transmission distance to tens of kilometers, and ensures superior signal integrity and reliability compared to traditional copper-based systems.
Feature
● High-Bandwidth Video Transport: Supports 4 independent bi-directional 12G-SDI channels, enabling transmission of 4K/UHDp60 (12G-SDI) or quad-link 3G-SDI/HD-SDI signals.
● Integrated Return Path: Features 2 dedicated 12G-SDI return channels for video, audio, or data communication (e.g., intercom, tally, camera control).
● Converged Network Transport: Incorporates a standard 10/100/1000BASE-T Gigabit Ethernet port, allowing control data, IP audio, or ancillary data to be multiplexed with video over the same fiber.
● Long-Distance Transmission: Utilizes single-mode SFP+ optical transceivers (sold separately), supporting link distances up to 20km, 40km, or 80km based on SFP+ module selection.
● Robust Signal Integrity: Advanced re-clocking and signal equalization on all SDI inputs ensure jitter elimination and recovery of degraded signals from long copper cables.
● High Reliability: Dual, hot-swappable,power supplies (AC/DC) with wide voltage input range. Fan-less design for silent operation.
● Comprehensive Monitoring: Front-panel LEDs for power, link status, signal presence, and errors. Supports SNMP for remote network management.
Application
HZT-SDI-12G-4V2V1E-SM001 is engineered for mission-critical environments where high-bandwidth, low-latency, and reliable signal transmission over long distances are paramount. Its converged design makes it ideal for:
● Broadcast & Live Production:
● Remote Production (REMI): Transmit multiple camera feeds (4x 12G-SDI) from a stadium or venue back to a central production truck or studio over a single fiber, while sending program return and comms signals (2x Return SDI) to the site. The Ethernet channel can carry control data for cameras, audio matrices, or IP intercom.
● Studio-to-Transmitter / OB Van Links: Create a robust, high-capacity link between a broadcast center and a remote transmitter site or between an OB van and a fixed facility, consolidating video, audio, and data networks.
● Large-Scale AV & Pro AV Integration:
● Convention Centers & Stadiums: Distribute 4K source signals (e.g., from a central head-end) to multiple distant displays or projectors across a vast campus, using the return path for screen status feedback or source switching commands.
● Command & Control Rooms: Facilitate the ingestion of multiple high-resolution data visualizations, network monitoring feeds, or surveillance video walls from dispersed locations into a centralized operations room.
● IP Migration & Hybrid SDI/IP Infrastructures:
● Hybrid Bridge: Serves as a crucial node in transitioning from pure SDI to IP (ST 2110) infrastructure. It extends the reach of existing SDI equipment over fiber while providing a dedicated Gigabit Ethernet path for early IP-based devices or network management, allowing for a phased migration.
● Corporate & Education:
● Distance Learning & Telepresence: Enable high-quality, multi-camera interactive lectures or executive communications between geographically separated campuses or corporate offices with broadcast-level video fidelity.
● Telecommunications & Service Providers:
● Contribution Links: Provide broadcasters or content distributors with a reliable, high-capacity "fattened pipe" for backhauling multiple channels of live or recorded content to a network operations center (NOC) for processing and distribution.
