EDID and HDCP Communications

On the fiber optic link, the video component of the signal always travels in one direction, from TX to 
RX.  However, the extender employs wavelength-division multiplexing (WDM) to support additional 
bidirectional signals over the same optical fiber.  This enables the device to support live EDID and 
HDCP communications.

Maximum Cable Lengths

The maximum cable length supported by the extender pair will vary based on whether or not the 
signal is HDCP encrypted as well as the type of fiber being used.  The HDCP encryption handshake 
process occurs every two seconds and the response from the display must be received by the source 
within a finite period of time.  Regardless of the cable type being used, at lengths beyond 1,000 ft. 
(~ 300 meters), the propagation delay as the signal transverses the optical fiber is greater than the 
response time allowed by the HDCP standard.  For non-encrypted signals, however, much greater 
extension distances are possible.  See the chart below for more details.
