MUX 3 SDI + 1 MADI (tx)

This card receives in its entrances three SDI signals, one MADI signal (with electrical format or optician), and one data signal RS-22. MADI is the resulting signal of the multiplexation of up to 56 digital audio channels Aes-ebu. All these signals are multiplexing to construct a DS of high speed that will take to the optical transmitter (High Digital Speed Optical TX). This signal will reconstruct in the receiving side in card DEMUX 3 SDI + 1 MADI.



High Speed Digital Optical Transmitter (tx)

This card receives in its entrance the DS of high speed provided by the Mux, and directly it modulates a laser module to obtain an optical reply of the electrical signal of entrance. This optical signal is injected in a fiber monoway through a connector SC to the optical receiver (High Digital Speed Optical RX) . This card is available in different wavelengths, 1310 nm, 1550 nm and all grill ITU, and optical power of 0dBm or 6dBm.

High Speed Digital Optical Receiver (rx)

The optical receiver is the card that receives the transmitted optical signal from any one of the optical transmitters, and turns it on an high speed electrical signal compatible with the Demux card 3 SDI. This card is available in two types of sensitivity to the optical signal, 20 dBm and -32dBm.





DEMUX 3 SDI + 1 MADI (rx)

The Demux card receives the NRZ signal from the optical receiver (High Digital Speed Optical RX), giving rise to three SDI signals and one MADI signal (in electrical format as optician) and one data signal when coming out.







Also a more basic version of the Mux and Demux cards without the MADI signal is available.

3 channels SDI + 1 MADI + 1 RS-422 configuration

High Speed Digital Optical Transceiver (TX/RX)

This card integrates the functionalities provided by the "High Digital Speed Optical TX" card and "High Digital Speed Optical RX" card. It receives a high speed digital signal provided by "MUX 3 SDI + 1 MADI" card, and to give a reply in laser form, as well as, at the same time, to receive a laser signal and to provide its electrical reply of high speed for a "DEMUX 3 SDI + 1 MADI" card. The card behaves therefore like a "transceiver". The optical signal is received through a optic fiber monoway with two E2000 connectors.

This card provides the possibility of mounting lasers CWDM with wavelengths of 1470nm, 1490nm, 1510nm, 1530nm, 1550nm, 1570nm, 1590nm and 1610nm.

1 SDI/DVB-ASI Optical TX (tx)

Transmitting unit of a channel SDI or DVB-ASI. When being a card monochannel, any multiplexación is not necessary, and the signal is modulated directly to a laser diode, obtaining an optical reply of the electrical signal. This optical signal is injected in the fiber through a E2000 connector to the optical receiver (1 SDI/DVB-ASI Optical RX). Optionally, this card offers the possibility of error monitoring of errors in the EDH checksum and regenerción of the same one to allow the state monitoring of the optical connection. This card is available in the wavelengths of 1310nm and 1550nm with -8dBm of optical power and in all grill CWDM with 3dBm.



1 SDI/DVB-ASI Optical RX (rx)

It is the complementary card in the side of the receiver of the previous card. This card is able to receive an optical signal and to turn it its electrical retort in format SDI or DVB-ASI. Like the optical transmitter, exists the possibility of analysis EDH.






All these cards are lodged within the Vlink coffers of 1 or 3 units of height. The "Vlink 1U Rack Frame" has a 3 slots capacity for 3 VLink-D cards. The "Vlink 3U Rack Frame" has 12 vertical slots for 12 VLink-d cards. All VLink-D cards has been designed to allow to its insertion and extraction in hot.
