DVI Extenders allow you to extend DVI devices up to 300ft away over Cat5e/Cat6/Cat7 cables and up to 3280ft away over fiber optic cables. They come in single, double, 4, or 8 port DVI splitter extender units which extend to one/two/four/eight devices correspondingly. These digital extenders are comprised of a transmitter and receiver, but usually sold separately. The transmitter unit connects to the DVI source and the receiver unit connects to a DVI display. Most units support a maximum 1920×1200 resolution, but the supported resolutions can vary according to distance. DVI Extension devices are most commonly used in corporate offices, educational institutes, medical and scientific facilities, and other large industrial buildings that need to connect audio/video DVI equipment.
What Cat5 DVI Extender is Best for my Situation?
Integrators needing to connect a single video device for remote observation of an industrial area that requires no human interaction, over a distance up to 300ft, should consider using a product like the 1 Port DVI Extender over CAT5e/6 (DVIE-101TR), which is capable of supporting a maximum 1920×1200 resolution over 115ft with a maximum 800×600 resolution at 300ft. This device includes a transmitter and receiver. The receiver can be located at a remote site, and from there gain and equalization adjustments can be made.
Users wishing to connect two DVI LCDs or TVs up to 300ft away like two projectors in a church with control room to view video should use a device like the 2 Port DVI Extender Splitter over CAT5e/6 Cable (DVS-102C). The Two Port Extender has the same specifications as the single port extender, but it has two RJ45 outputs for transmitting the DVI signal and one local DVI output. It also needs separate video receivers. A nice feature of this device is that it can support audio transmission as well. However, the audio signal requires a second Cat5 cable and a separate audio receiver.
Video Managers wanting to remotely control a single device using bi-directional USB, RS232 or IR, should use the HD based-T capable product like a HDBaseT DVI KVM Extender (SDX-PLUS-S). This Cat6 extender is capable of supporting a maximum 1920×1200 resolution at 60Hz. This unit includes the transmitter and receiver with support for remote RS232 and USB 1.1 control. It has a maximum distance of 330ft.
Anyone wishing to connect a single device over extreme distances (as far as 3280ft) and needing to limit electromagnetic interference, should use an item like the DVI Extender with EMI Shielding over Single Multimode Fiber Optic (DVI-1STRSD). The Fiber Optic DVI Extender connects with fiber optic cables and supports WUXGA 1920×1200 resolution. This unit includes the transmitter and receiver. This extender is very popular among medical and scientific fields because of the EMI shielding. This allows sensitive equipment and personnel to be located far away from hazardous working conditions.
All the devices above are one input and single source. Anyone wanting to connect more than one source should use a DVI Matrix. To find more affordable video products, see www.KVMSwitchTech.com or contact our support team at 866-865-7737.
