Crystal Vision
Introduction
1 Introduction
The FTX-VF is a dual channel, reclocking, 3G/HD/SD video to fibre transmitter that
can be
used with single-mode or multi-mode fibres and meets the SMPTE 297-2006 short-haul
specification. Distances in excess of 10km are possible with single-mode fibre depending on
cable quality and number of connectors and splices (see
Fibre distance calculations guide
).
Optional CWDM lasers are available which, with an external combiner, enables the
transmission of two video signals down a single fibre for up to 50km.
FTX-VF is a space-saving 96mm x 325mm
module which fits in the standard Vision frames
from Crystal Vision, with the inputs and outputs accessed by using the VR14 rear module.
Status monitoring and control is by the Vision frame active front panel, remote VisionPanel
control panel, SNMP or VisionWeb PC software
.
In addition to the fibre output
,
FTX-VF
provides two reclocked loop-through video outputs per
channel.
FTX-VF
provides remote monitoring of video input presence and warnings of low laser output
(failure) and high bias current (imminent failure). The laser output automatically turns off if the
input video is removed and can be remotely turned on and off as required.
