Fiber optic video cable basics and purchase guide.
What needs necessitate an installer to consider fiber optic cables?
The main reasons can be summed up easily:
long cable run (up to 20Km/12.4Miles)
Reliably perfect video signals
EMI or RF Interference
Isolation of power between cable runs, no ground noise interjection
Fiber optics are excellent solution for the common problems that arise
with using copper cables for distances over 75 feet and longer, like
signal loss and interference.
In digital video environment where images and sound are delivered as
data, transmitting the information without loss or error is key to image
To achieve this reliably, data is driven by light driven by transmitter/receiver (Tx/Rx)
processors. Fiber optics are commonly used in medical and retail
applications, ideal for use in simulation, digital signage, aircrafts,
studios, and other mission critical environments. Some fiber optic transceivers
(transmitter/receiver) also support additional functions, such as IR,
audio, or RS-232 connections. The types currently available on the
The types of Fiber Optic cables:
The most common and affordable
solution is the full cable with the transceivers built into the heads of
the cable connector, ideal solution for shorter fixed
distances. Fiber Optic cables are available in lengths from 10 to
100 meters in DVI or HDMI.

For times when pulling connectors through walls or conduit is too
difficult or virtually impossible, extender modules
(often called dongles or TX/RX) can be attached once the cable is in
place. This allows choices of cable that fits the
environment, unique cables like transparent, indoor/outdoor or plenum.
Fiber Optic transceivers consist of the
sender and receiver that connects to cables ends. This allows
pre-installing the cables during construction.
wires can be the older 4-wire multi-cables or single cables terminated as the industry standard
LC or SC types. Fiber cables are sold in different lengths
from 10 to 150 Meters pre-terminated, or up to 300 Meters
and longer as
custom made orders. Transceivers are available in DVI, HDMI or
SDI, or DisplayPort.

How about HDCP?
an assumption could be made that all HDMI cables all support HDCP, the
same is not true for DVI connections. Most multiple-wire DVI
cables are HDCP compliant, but same is not true for single wire units.
To ensure compatibility with most consumer equipment, be sure to check
for HDCP compliance before purchase.
