Optical Transmitter/Receiver/Repeater

Information About the DLC300

This manual introduces the DLC300 function module, which is a multi-functional digital video ber 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 congure 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 congure 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 Conguration 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.

DLC300 Function Module

Signal Paths

The primary signal path of the DLC300 is determined by the mode in which it operates, which are as follows:

• Transmitter mode—Electrical input to optical transmit

• Receiver mode—Optical receive to electrical transmit

• Repeater mode—Optical receive to optical transmit

Both hardware and software provide exibility in routing, such as allowing the selection of input and output

paths.

The DLC300 allows you to select one the following transmitter sources:

• Electrical input BNC (transmitter mode)

• One of the other DL4000 chassis slots (transmitter mode)

• Optical receiver output (repeater mode)

The receive path is connected to the electrical outputs and is also made available to the function modules

located in the remaining chassis slots.

The monitor output is determined by the operating mode of the DLC300. When the DLC300 is operating in

either receive or repeater mode, the monitor displays the received signal.When the DLC300 is operating in

transmitter mode, the monitor displays the transmitted signal.

Electrical Input

The electrical input is a precision 75Ohm BNC and includes an automatic cable equalizer. This input passes

through a multi-rate reclocker that detects the signal rate but is format transparent.

When no input signal is connected and the DLC300 is in transmitter or repeater mode, the DLC300 transmits a

standby signal to the optical receiver to maintain the optical link between modules. The DLC300 can transmit

either an SDI video or a PRBS143 non-video standby signal.

Note: For optimal performance, follow the recommendations stated in the DLC300 data sheet for full

cable lengths and cable types.

Electrical Outputs

The electrical output is a precision 75Ohm BNC with a multirate cable driver.

The mini 75Ohm SMB monitor jack (MON) located on the front panel also provides an electrical output (see

the“Signal Paths”section on page 4)

Receive electrical output is provided on the output BNC through a multirate driver directly connected to the

receive path reclocker. The electrical output signal is also made available to the function modules located in

the remaining DL4000 chassis slots.

Note: For optimal performance, follow the recommendations stated in the DLC300 data sheet for full

cable lengths and cable types.

DLC300 Module Overview

Optical Input and Output

The optical interfaces are provided by two SFP sockets; a primary SFP (PRI) and a secondary SFP (SEC). Each

SFP uses LC/PC connectors. Optical performance is dependant the quality of your optical ber and ber

interconnects, and on the selected SFP, which must be specically qualied by Artel. Consult Artel for available

SFP options.

DLC300 Function Module Installation and Operations Manual 7

Conguring the DLC300 Module Operation

This section describes how to congure the DLC300 mode of operation and the function of the transmit and

receive signal connections. You congure the DLC300 to operate one of the following modes:

• Transmitter mode—The optical transmitters are enabled and the optical receivers are disabled. The

DLC300 operates as an electrical-to-optical transmitter.

This mode supports the following I/O connections:

– Input—A single electrical input is accepted from either the digital video IN BNC connector or one

of the four backplane connectors.

– Output—The optical output is available at both SFP transmitters. The electrical output is available

on the BNC OUT connector and the monitor jack. The monitor jack output signal is undithered

when the dithering DIP switch is enabled.

The DLC300 auto-congures for one or two SFPs. When operating with just one SFP, you can use either the

primary or secondary SFP socket. When no electrical input is detected, the DLC300 transmits a switch-

selectable standby signal; either SDI video or a PRBS143 non-video standby signal.

The DLC300 detects the incoming bit rate and its processing feature includes SDI EG-34 dithering. When

you congure the DLC300 to process the input signal, it adds dithering to SDI.The dithering processing

makes the DLC300 optical output compatible with DWDM networks for any of the applied signals.

• Receiver mode—The optical receivers are enabled and the optical transmitters are disabled. The

DLC300 operates as an optical-to-electrical receiver.

This mode supports the following I/O connections:

– Input—An optical input is accepted from one or both SFP receivers.

– Output—The electrical output is available at the output BNC (OUT), the four backplane

connectors, and the monitor jack.

• Repeater mode—The optical receivers and transmitters are both enabled. The DLC300 operates as

an optical-to-optical repeater.

This mode supports the following I/O connections:

– Input—An optical input is accepted from one or both SFP receivers.

– Output—The optical output, which has been reclocked to assure the optimal performance in

long-haul applications, is available at both SFP transmitters.The electrical output is available at

the output BNC (OUT), the four backplane connectors, and the monitor jack.

The switches that control the functionality of the DLC300 are the SW1, SW2, and SW3 conguration DIP

switches and the SW4 mode select switch (see Figure 2).

Dual SFP optics provide optical redundancy and work in transmitter, receiver, and repeater modes. They can

also serve as an additional output source for fanout purposes in transmitter and repeater modes.The DLC300

switches over to the secondary SFP when the input signal to the primary SFP is lost. If you enable the optical

reversion feature, the optical input selector reverts to the input signal on the primary SFP receiver if the signal

on this SFP returns.The default reversion time is set to one minute, which means that

8DLC300 Function Module Installation and Operations Manual

DLC300 Function Module

the DLC300 does not revert back to the primary SFP signal until it has returned for one minute.You can modify

the length of the reversion time using DL Manager (see the DL Manager Setup and Operations Manual). The

optical reversion feature is disabled by default. For information about enabling this feature, see the“Setting

the SW3 Conguration DIP Switch”section on page 11.

Default Conguration Settings

Artel ships the DLC300 congured as follows:

• Transmitter mode selected

• All signal types allowed

• Electrical input set to BNC

• Standby signal set to Artel non-video standby signal

• SDI Standby set to 525 line (SD-SDI), 59.94 fps (HD/3G)

• Forced bypass is disabled (when forced bypass is enabled, all signal classication, dithering, and

reclocking is bypassed)

• SDI processing set to no EG-34 dithering

• ATSC to ASI conversion is disabled

• SFP alarms are enabled

• Optical reversion is disabled

• Video loss alarm is disabled

• EMS override is enabled (EMS can change the DLC300 conguration)

Note: You congure the DLC300 while the module is out of the chassis because the mode select

switch and the conguration DIP switches are mounted to the top of the module PCB.
