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.
Optical fiber interconnection between transmitter and
receiver
Number/type ................................ 1 or 2 ber optic
N
Only one fiber is required to transmit video, audio, and
unidirectional data. A second fiber is required to transmit
return data for bidirectional control/communication.
Connectors ..................................... 2 LC connectors
Operating distance ........................ 30 km (18.75 miles) with singlemode (SM)
cables with a FOXBOX 4G SM
0.15 km (492') with multimode (MM)
cables with a FOXBOX 4G MM
N
Operating distance is approximate. These are typical
distances. The maximum distance may be greater than these
typical numbers depending on factors such as fiber type, fiber
bandwidth, connector splicing, losses, modal or chromatic
dispersion, environmental factors, and kinks.
