ROC3-DWDM40S-D - AAWG 40 channels DWDM demux card for ROC3 Chassis, managed

Product description

The ROC3-DWDM40S-M and ROC3-DWDM40S-D cards are essential components of a DWDM deployment. These cards allow up to 40 channels of DWDM ITU 100GHz grid to be multiplexed over a single strand of single mode fiber. Cards support channels 21 to 60 in the ITU grid (wavelengths 1529.55nm to 1560.60nm). The technology used is called AAWG (Athermal Arrayed Waveguide Grating), allowing a large number of channels to be aggregated for a very low insertion loss compared with traditional DWDM multiplexers. Using AAWG multiplexers 40 channels of DWDM can be easily put together. DWDM technology allows maximum possible bandwidth from a dark fiber and also benefits from EDFA light amplifiers to extend reach. DWDM and EDFA cards often go together in optical transport applications. For the AAWG DWDM 40 channels multiplexers there are two available cards: ROC3-DWDM40S-M and ROC3-DWDM40S-D, mux and demux units which are intended to operate in a point-to-point set. This page is about the demultiplexer (demux) unit called ROC3-DWDM40S-D. For the multiplexer unit (mux), please visit ROC3-DWDM40S-M page.

The ROC3-DWDM40S cards fit into any of the ROC3 chassis: either ROC-CH04, ROC-CH08 or ROC-CH16 model. There are many other optical cards for the ROC3 platform, all can be managed via ROC3-NMC card. Among the optical cards available for ROC3 platform we can find transponders for 100G, 25G, 10G and even lower speeds such as Gigabit or Fast Ethernet, CWDM mux demux cards, EDFA amplifier cards or optical 1:1 protection cards. Many other function cards, such as DCM compensation modules, Optical Switches, Variable Attenuators or FWDM cards are also available for the ROC3 chassis. Platform is dimensioned for 19" rack mounting and has 23" rack adapting brackets available on demand. 

The ROC3 chassis series provide redundant power supply system with "hot swap" feature, to provide continuous smooth operation of the units installed. The ROC3-EDFA cards are also hot-swappable, settings are stored in the ROC3-NMC management card. In case of a protection card malfunction, card can be removed and a newly inserted card will automatically be programmed by the NMC card with previously saved configuration, so the chassis keeps running unimpeded and without any programming effort from technician to recommission the new card.
