8-Port PoE Switch + 6-Ch Forward 2-Ch Return 3G-SDI Fiber Extender
Overview
The LNK-3GSDI-6FV2BV8GP is a professional fiber optic extender integrating 8 Gigabit PoE ports
with 6 forward 3G-SDI and 2 return 3G-SDI channels over a single optical fiber. Designed for
broadcast studios, surveillance networks, and live production, it delivers uncompressed SDI
video (SD/HD/3G-SDI) with embedded audio, while simultaneously powering IP cameras or other
devices via IEEE 802.3af/at PoE. Featuring built-in CWDM multiplexing, rackmount 2U form factor,
and 20km optical transmission distance, it provides a scalable and secure transmission solution
where reliability is critical.
