Switching and Routing Fiber Optic WDM AV Signals



A matrix switcher for WDM signals is larger and more complex than that used for a TDM signal as shown in Figure 1. Each fiber optic input includes the complete WDM receiver circuit to convert the optical signal to an HDMI/DVI format. The core switching system supports the multi-lane format of an HDMI/DVI signal, which requires multiple, parallel internal switching components. Each fiber optic output includes the complete WDM transmitter circuit to convert the HDMI/DVI signal back into an optical signal.

The additional switching resources and I/O circuitry causes WDM matrix switchers to be large, high powered, and require additional cooling. Since the core switching system supports HDMI/DVI signals in their native format, local inputs and outputs are easily added to the matrix. Supporting other signal types, such as 3G-SDI, requires external converters to change the original signal into a DVI/HDMI signal. WDM matrix switchers do not typically support local 3G-SDI signals.
