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:

  • Very long cable run (up to 20Km/12.4Miles)

  • Reliably perfect video signals

  • No 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 fidelity.  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 market: 

The types of Fiber Optic cables:

lntegrated 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.

Extender Modules.  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. 

The 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?

Important Note:  While 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.
