What Is Driving Adoption of High Density Fiber Enclosures?

Real estate is one of the primary reasons that high density fiber enclosures are deployed in the data center. In some parts of the world, real estate is very expensive. One way to save cap ex is to try to use the smallest data center possible. The smaller the data center, the less square area required, and therefore, lower cap ex. This would certainly be the case if one is using a co-lo facility. Of course, a smaller data center also means lower op ex, e.g., less cooling, etc.

Another reason, also driven by real estate, is that the data center’s size is fixed. The data center cannot be enlarged. This might be the situation in dense urban areas where a larger space does not exist. The only way to add more functionality to the data center is to try and find a way to cram in more equipment. Hence, using a high density fiber enclosure.

Another less obvious reason for using a high density fiber enclosure is the trend towards data centers becoming profit centers. Historically, data centers were perceived as a cost of doing business. Depending on the business you are in, that may no longer be the case.

Hasn’t Everyone Deployed 10G Ethernet?

The other day I was participating in a conversation with a customer about LAN and SAN speeds greater than 10G. It was a good conversation and the customer had numerous questions about migrating to 40G Ethernet; what is happening with 100G Ethernet, using multiple fibers for Fibre Channel, etc.

Toward the end of the conversation I asked them about their plans regarding deploying 40G Ethernet. They replied that they had no immediate plans for deploying 40G and that the reason they wanted to talk about it was to make sure that their LAN infrastructure could support it in the future. They plan on deploying 10G Ethernet in the new data center.

That revelation hit me with the same impact as participating in an ice bucket challenge.

Practicing Good Fiber Hygiene

There is something lurking about in today’s data centers that is not mentioned in polite company and quite frankly, is ignored. Although it will not go away, one hopes that it will not rise up and wreak havoc, bringing the enterprise to a halt.

That’s right . . . bad fiber hygiene!

EEEK!

Helping You Manage Your Network: Tapped Fiber Cassettes

Data center networks are becoming more and more complex making it more difficult to trouble shoot and balance traffic within LANs and SANs. That is why more network architects and data center managers are deploying Tapped Fiber optic Cassettes (TFC).

Basic TFC Usage TFCs give network analyzers, packet brokers, and other pieces of test equipment access to the fiber link.

So, what are TFCs and how do they work?
