Standalone passive multiplexers are often used within xWDM systems to avoid the use of passive components in active module slots in chassis.
With the CWDM multiplexers MICROSENS offers cost-efficient solutions to extend active CWDM systems with multiplexers, but also to enable passive CWDM solutions (CWDM transceiver is installed directly in the upstream switch).
The CWDM channels are standardized according to ITU-T G.694.2.This means MICROSENS multiplexers are compatible with other CWDM systems and standardized CWDM transceivers.
MICROSENS offers two CWDM multiplexer versions, whereby multiplexing and demultiplexing are always implemented within the components:
- 8-channel CWDM multiplexer (1470 - 1610nm, 20 nm channel spacing)
- 18-channel CWDM multiplexer (1270 - 1610nm, 20 nm channel spacing)
Both versions are 19", do not require a power supply (MICROSENS definition for "passive device") and are completely protocol transparent. The CWDM multiplexers also have no limits with regard to the data rate to be transmitted; the limits are determined by the active technology and the fiber quality of the transmission path.
When using the 18-channel CWDM multiplexer, it must be ensured that the frequencies of 1270nm - 1450nm have an increased attenuation budget. This is due to the physical conditions. This should be taken into account in CWDM planning.
