Extron FOXBOX 4G DVI, FOXBOX 4G VGA Series Fiber Optic Transceivers • Specifications
N
The FOXBOX 4G DVI and FOXBOX 4G VGA consist of a transmitter
(FOXBOX 4G DVI/VGA Tx) and a receiver (FOXBOX 4G DVI/VGA Rx) with one or two fiber
optic cables linking the two units. They are available in singlemode or multimode versions.
N
For the VGA models, the analog RGB input signal is digitized pixel for pixel in the transmitter, sent
digitally through the fiber cable, and converted back to analog RGB in the receiver.
N
The analog audio signal(s) is (are) digitized in the transmitter, sent through the fiber cable, and
converted back to analog audio in the receiver.
N
These transceivers are class 1 laser products. They meet the safety regulations of IEC-60825,
FDA 21, CFR 1040.10, and FDA 21 CFR 1040.11.

Operating distance is approximate. These are typical maximum distances that may vary depending
on factors such as fiber type, fiber bandwidth, connector splicing, losses, modal or chromatic
dispersion, environmental factors, and kinks.
