CWDM 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. This is an extremely simple way of performing a sophisticated convergence function without needing to resort to complex technology. Convergence simply becomes a matter of fibre plumbing.

The MetroWAVE product range has the advantage of performing the CWDM multiplexing and demultiplexing functions passively, i.e. directly optically without using any conversions to electrical and then back to optical. This means that the MetroWAVE products are completely unpowered devices, which means that they have much greater robustness and reliability than active devices performing similar functions.

The widespread availability of vendor compatible CWDM SFPs means that the optical-electrical-optical conversion process performed by active CWDM equipment is no longer required.

The MetroWAVE product family has several members:

• MetroWAVE-9S : 8+1-channel (1471nm to 1611nm + 1300nm band) CWDM multiplexer with monitor port
• MetroWAVE-8A : 8-channel (1271 to 1411nm) CWDM multiplexer - add on to MetroWAVE-9S to support 16-wavelengths of CWDM
• MetroWAVE-CWDMmeter : 18-channel CWDM power meter
• MetroWAVE-rack : mounts 3 off MetroWAVE WDM multiplexers into 1U of a 19 inch rack

The MetroWAVE-9S product operates in the upper 1550nm CWDM band with support for the lower 1300nm CWDM band via a wideband 1300nm port. This means that they can support direct connection of legacy 1300nm non-CWDM equipment, or alternatively expansion into the lower 1300nm CWDM band. The MetroWAVE-8A offers lower CWDM band expansion capability, so in conjunction with the MetroWAVE-9S, solutions offering up to 16-wavelengths of CWDM can be supported.

The MetroWAVE-CWDMmeter allows all 18 off CWDM channels to be monitored simultaneously, which when used in conjunction with the monitor ports enables easy but sophisticated system level debug.

Whilst the MetroWAVE product range is compatible with industry standard user exchangeable SFPs, it is recommended that these are purchased from Metrodata for use in Metrodata fibre equipment to guarantee their specification and compatibility with each other.

Metrodata can also supply a wide range of vendor compatible fibre transceivers for use in your routing, switching or SAN infrastructure including SFP, SFP+, XFP, X2 and XENPAK including long distance, CWDM and DWDM variants, or 40G QSFP+.
