The CVD 4210 and CVD 4220 Fiber
Optic Communication products by Covid allow direct connection
of computer video for signal transmission over Fiber Optic cable.
Spanning distances to three kilometers, the CVD 4210 and CVD
4220 feature excellent picture quality through bright, sharp
images without the signal degradation and smearing of coax at
extended lengths. Signal integrity is also maintained through
fiber optic cable’s immunity to electrical interference
and cross-talk. Fiber optic cable has certain intrinsic benefits
for installation success including resistance to electromagnetic
interference (EMI), lightning, and the elimination of ground
loops through electrical isolation. Tactical and Military installations
often require fiber due to high security capacities.
