A Simple Solution to a Big Colocation Challenge

A Simple Solution to a Big Colocation Challenge

Colocation data centers play a vital role in today’s networking world. However, one of the biggest challenges colo customers can face is the extremely high cost of fiber cross-connects within the data center, particularly in North America where monthly fees are charged per fiber used. If you require upwards of dozens of cross-connects, this annual cost could very easily exceed $100,000. Under these circumstances, wouldn’t it be great to get, say, 40 services onto one cross-connect fiber?

You absolutely can. And quite simply, too!

The solution here is single fiber DWDM passive filters. In particular, this application calls for a 80-channel (40-service) mux that operates as depicted in the diagram below:

This solution operates similarly to the “two-channel services” method we’ve previously discussed: as shown above, each service transmits and receives on adjacent channels like a standard single fiber solution. However, utilizing the ITU “half channels” (50GHz spacing) maximizes port density in a single rack unit, enabling 40 services while keeping rack space to a minimum.

For additional cost savings and operational simplicity, you could also consider tunable DWDM transceivers as an ideal complement.
