SAE-4HDM2bA-TRX is a high-performance fiber optic video and audio transceiver, designed to transmit up to 4 HDMI video streams (up to 1080p Full HD) along with 2 channels of bidirectional stereo audio over long distances via fiber cable.
Leveraging advanced high-bandwidth optical transmission technologies, the device enables lossless, uncompressed video and audio delivery over distances exceeding 20 kilometers (depending on module and fiber type). It maintains full compatibility with HDMI standards including HDCP and EDID protocols, and supports a variety of audio interfaces depending on deployment requirements.
The unit’s rugged industrial-grade design ensures consistent performance even in extreme environments ranging from -40°C to +65°C. Its plug-and-play nature means no configuration is needed — just connect and transmit.
Available as both standalone and rack-mounted units, this transceiver is ideal for video walls, command centers, transportation monitoring, and secure video broadcasting over fiber infrastructure.
With LED indicators for each channel, operators can instantly verify signal integrity, power status, and system health.
