Five DVI models across 1080p and 4K — mini extenders with RS232, dual-purpose HDMI/DVI units — plus the VGA case handled the honest way: as a section, not a fake product line.
DVI was supposed to be retired by now. Instead it persists exactly where reliability matters: graphics workstations in control rooms, medical imaging, industrial HMIs, simulation and older high-end displays — equipment with long service lives whose video output is a DVI port. Those machines also tend to sit far from their displays, and DVI copper is even less forgiving than HDMI. This family converts DVI to fiber in both its generations: three 1080p models and two 4K models.
The documented details reward a look. The Mini 4K DVI Fiber Optic Extender carries RS232 beside the video — the serial channel that touch overlays and control systems need. The larger KVM-pattern units in the video range combine HDMI/DVI inputs with loop outputs and USB, so a workstation can be relocated to a machine room and operated from a quiet desk. VGA appears in this catalogue only as legacy demand: rather than inventing a VGA product line, this page treats VGA sources in the specifying section below.

The 1080p DVI family (3 models) and 4K DVI family (2 models) combined, as listed in the manufacturer's catalogue.
DVI-D (digital), DVI-A (analog) and DVI-I (both) are not interchangeable, and single-link vs dual-link decides the resolution ceiling. Identify the exact port type on your source before anything is quoted; the conversion path depends on it.
VGA is an analog signal and this catalogue contains no VGA fiber converter line — we will not list one that does not exist. A VGA source reaches fiber by first being converted to a digital interface (or served by a converter with an analog input where a project documents one). If your plant has VGA sources, describe them in the inquiry and we will specify the conversion chain honestly rather than sell a mismatched box.
Touch and control at the display end usually means RS232 or USB returning along the link. The mini 4K model documents RS232; KVM models document USB. Name the return channel in the inquiry.
DVI-D and HDMI video signals are closely related, and several units in the wider video range are dual-marked HDMI/DVI. The workable combinations are model-specific — describe both ends in the inquiry and the pairing will be confirmed in writing.
DVI itself carries no audio. If the position needs sound, it travels as a separate channel — several video-family models add analog audio; state the need when inquiring.
Support is per model. State your resolution and whether the source is single or dual link; that answer filters the family immediately.
Send the model name, the distance, the fiber type and the quantity. We will confirm the matching transmitter/receiver pairing, the optical module and the full specification of the exact model in writing before you pay.
