Passive 8 Channel DWDM Multiplexer

Passive DWDM Multiplexer

• Optical multiplexing of up to 8 separate DWDM applications
• CWDM compatible uplinks (CWDM channels 1550nm & 1530nm respectively)
• Voice, data, telemetry and CCTV can all be supported
• Simple fibre 'plug & play' connectivity to converge complex applications
• Wide range of DWDM Transceivers available
• Unpowered passive devices for highest possible reliability

The MetroWAVE product range offers a series of passive CWDM and DWDM optical multiplexing functions. CWDM and DWDM multiplexing is a technique whereby different wavelengths of light are multiplexed together and transported over a singlemode fibre pair, then demultiplexed at the far end back into their original wavelengths.

The MetroWAVE product range performs these CWDM and DWDM multiplexing and demultiplexing functions passively, i.e. directly optically without using any optical-electrical-optical conversions or repeater functions. This is now the most economic approach to CWDM and DWDM multiplexing due to the widespread availability of cost effective long range vendor compatible CWDM and DWDM fibre transceivers. The unpowered, fixed mechanical nature of these MetroWAVE products offers greater robustness and higher levels of reliability than active devices offering similar functionality.

The MetroWAVE-D8-25 and MetroWAVE-D8-51 operate in the 100GHz DWDM C-band (ch25-ch32 and ch51-ch58 respectively). The combined uplinks operate within CWDM channels 1550nm and 1530nm respectively, facilitating optional cascade connectivity from the corresponding ports of the MetroWAVE-9S CWDM Mux/Demux, thereby providing an excellent 'expansion' option for that product.

Whilst the MetroWAVE product range is compatible with user exchangeable SFP, SFP+ and XFP devices (along with most other industry standard fibre transceivers), it is recommended that these are purchased from Metrodata to guarantee their specification and compatibility with each other.
