1 The SDI-TD-MUX-4 and SDI-TD-DMUX-4 at a glance
The SDI-TD-MUX-4 is a Flashlink time-division multiplexer (TDM) that allows any
combination of four SD-SDI or DVB-ASI inputs to be transported over a single HD-SDI link
according to the SMPTE 346M-2000 standard.
The SDI-TD-DMUX-4 is a Flashlink time division de-multiplexer that recovers the four SD-
SDI or DVB-ASI input signals from the SMPTE 346M-2000 compliant transport signal.
The key features of the combination SDI-TD-MUX-4 / SDI-TD-DMUX-4 include:

Accepts any synchronous or asynchronous SD-SDI 270 Mbps input format as well as
270 Mbps DVB-ASI.

Automatic input format detection for each channel.

Mix of input formats allowed and correct format recovered at the de-multiplexer side.

Built-in routing switcher at both ends.

Separate stream clock reference data for each channel is transferred for remote clock
regeneration.

The four streams embedded in the HD-SDI are completely independent, no
contamination of remaining streams when one or more inputs are lost.

High performance optics for short and long haul applications available, including
CWDM laser option.

Optical and electrical 1.485 Gbps HD output TDM available simultaneously.

Change-over functionality between de-multiplexer electrical and optical inputs.

The transport signal is compliant with the SMPTE-346M-2000 standard, allowing use
of a standard HD infrastructure for transport and switching of the multiplexed signal.

EDH handling for the SD-SDI signals.

Multicon interface allows remote control, status monitoring, error reporting and SNMP
support.

1 Several wavelength/power options exist. From a control perspective all these versions are identical,
but the laser control block reports its parameters to the system controller.
