1. INTRODUCTION
The
SILVERLINE
VTX Miniature Fibre Optic Transmitter has been designed for use with
composite colour and monochrome video signals that fall within the frequency bandwidth
of 15MHz. As all current terrestrial broadcasting standards such as PAL, NTSC and
SECAM require only 5.5MHz of bandwidth they are eminently suitable for transmission
over fibre with this product. This product enables high quality video distribution over fibre
without the need for equalisation for distances up to 4km.
Because of the wide bandwidth of the Cove Communications
SILVERLINE
Fibre Optic
Video Transmitter and its video encoding systems independence, users can be confident
when using this product that they are relatively future proof against the introduction of new
composite video standards and compatibility problems. However the extended bandwidth
of the Cove Communications
SILVERLINE
Fibre Optic Video Transmitter currently allows
its use with high quality video sources such as some high quality, high resolution cameras
and will give far superior results compared to the use of coaxial cable even for relatively
short distances. The extended bandwidth also ensures that the new 16 x 9 aspect ratio
wide screen video format, which has a bandwidth of 7.5 MHz may be used with this
product.
