Information About the DLC300
This manual introduces the DLC300 function module, which is a multi-functional digital video fiber transport
module that can optically transport all digital formats from 19.39 Mb/s ATSC to 3G-SDI (SMPTE 424M) using
specialized video or standard multi-rate SFP transceivers. You can configure the DLC300 as a receiver,
transmitter, or repeater.
The DLC300 can transmit and receive external signals using the following built-in options:
•
BNC connectors and Small Form Factor Pluggable (SFP) ports for connecting to external devices
•
Backplane connector for connecting to other function modules in the DL4000 chassis
For transmitting and receiving optical signals, the DLC300 can use dual SFP optics available in WDM, CWDM,
or DWDM optical wavelengths. You can configure the DLC300 to use one or both SFPs. When dual SFPs are
used for redundancy, the DLC300 can automatically switch over to the secondary SFP when the input signal to
the primary SFP is lost. The DLC300 can also switch back to the input on the primary SFP if the signal on this
SFP returns.
The DLC300 can add SMPTE EG-34 style dithering to allow transmission over DWDM networks of video that
may contain pathological bit sequences. For more information about the DLC300 signal processing options,
see the
“Setting the SW3 Configuration DIP Switch” section on page 11.
The DLC300 also supports conversion of 19.39 Mb/s ATSC (SMPTE 310M) to 270 Mb/s DVB-ASI.
Provisioning and monitoring is accomplished using DIP switches, LEDs, front panel monitor jack, or Artel’s DL
Manager, which is an element management system (for more information, see the
DL Manager Setup and
Operations Manual
). The DLC300 also has a set of major and minor alarms that indicate problems related to its
on-board power supplies, optics, temperature, and the input signals.
