Note: Only the card is sold under this part number. The chassis is sold separately here.
The core of any CWDM application is the passive MUX/DEMUX filter unit. The new CWDM mux/demuxes from ROBOfiber adopt a modular format. Each mux/demux can be used as standalone unit or can be installed as card in a simple RB-CH04 chassis with 4 slots. The RB-CH04 chassis can be installed in 19" rack and occupies only 1U of rack space.
The RB5-MD81D-47-LCU mux/demux bundles the main 8 CWDM channels: 1471, 1491, 1511, 1531, 1551, 1571, 1591 and 1611nm and also adds an additional broad channel for 1310nm. This allows the CWDM solution based on this mux/demux to be deployed over an already existing 1310nm connection with a minimum downtime and minimal changes.
Once installed, the RB5-MD81D-47-LCU will provide additional 8 CWDM channels for increased capacity. Equipment is able to bundle and respectively unbundle up to 9 different optical wavelengths over a single fiber optic circuit. CWDM technology is basically using a gap of 20nm between each lambda. To assure communications over these wavelengths special CWDM SFP modules
must be used. The ninth lambda is the 1310nm wavelength 90nm wide channel that can be used with conventional 1310nm lasers. The ninth channel can be customized and be any other low band CWDM channel (1271to 1331nm). For mux/demux customizations, please do not hesitate to contact us
The complete CWDM mux/demux is the one using all 8 colored CWDM wavelengths doing an 8+1:1 (eightand1311nm-to-one) multiplexing.
There are many other options for CWDM and/or DWDM cards that would all fit the RB-CH04 4 slot chassis. 4:1, 16:1 simplex or duplex card options are available for the RB series of CWDM and DWDM filters. Custom made CWDM and DWDM filters can be executed for special application requirements.
For such design, please do not hesitate to contact us
