Analog Tri-level Sync over Fiber Extender
SDI Fiber Converter Overview
The E-link LNK-3G2V2BA2D1E1T1S represents an advanced fiber optic
transmission system engineered for mission-critical broadcast and
surveillance applications. This comprehensive solution integrates
seven distinct signal channels through a single fiber optic link,
combining bidirectional 3G-SDI video (SMPTE 424M compliant),
dual-channel analog audio return, RS422 data communication, 100M
Ethernet connectivity, tally signaling, and analog tri-level sync
transmission.
Utilizing sophisticated wavelength division multiplexing (WDM)
technology, the system ensures complete electrical isolation and
immunity to electromagnetic interference, guaranteeing signal
integrity across extended distances. The transmitter and receiver
pair operates seamlessly over single-mode fiber infrastructure,
supporting transmission ranges from standard 20km to extended 80km
configurations to accommodate various deployment scenarios.
Featuring robust IP network integration capabilities, this extender
enables seamless compatibility with modern broadcasting
infrastructures and IP-based surveillance systems. The advanced
optical engine delivers broadcast-grade video quality with
real-time processing, maintaining precise synchronization between
all audio, video, and control signals throughout transmission.
Specifically designed for live event production, outside broadcast
vehicles, and high-security surveillance operations, this fiber
extender provides a future-proof alternative to conventional
coaxial cable systems. Its multi-signal integration capability
significantly reduces infrastructure complexity while enhancing
system reliability, making it an ideal solution for professional
applications requiring uncompromised signal quality and operational
security.
