1Ch 1080P DVI + USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber Extender
Model: LNK-KVM-DVI-1D1BA1GO
Overview
The 1Ch 1080P DVI + USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber
Extender (model: LNK-KVM-DVI-1D1BA1GO) is a high-performance signal transmission device
engineered for long-distance delivery of multi-type signals via a single fiber optic cable. As a 1Ch
1080P DVI + USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber Extender,
it integrates comprehensive signal support, making it ideal for scenarios where high-quality, long-
range transmission of multiple critical signals is required.
This 1Ch 1080P DVI + USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber
Extender enables stable extension of DVI signals over long distances, while also supporting KVM
(USB-based), 1Ch RS232 serial signals, 1Ch GPIO (General Purpose Input/Output) signals, and
external bidi stereo audio transmission—all through one fiber optic cable. It delivers exceptional
visual performance with support for high resolution up to 1080P, ensuring crisp, clear image quality
for applications like video surveillance centers, industrial control rooms, and remote conference
facilities.
With excellent stability and robust security features, the 1Ch 1080P DVI + USB KVM + 1Ch
RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber Extender is suitable for a wide range of
professional applications that demand long-distance transmission of high-resolution signals
without quality loss. Whether used in industrial automation systems (to connect remote DVI
displays and KVM controls), large-scale monitoring networks (to transmit high-definition video
and audio), or corporate IT environments (for remote server management via RS232 and KVM),
this extender ensures reliable, secure signal transmission. Its all-in-one design simplifies cabling,
reduces installation complexity, and lowers maintenance costs, making it a versatile and cost-
effective solution for multi-signal long-distance fiber transmission needs.
