A white paper published by Fluke Networks includes a list of three characteristics users should look for in an optical time-domain reflectometer (OTDR) used to test fiber-optic cabling systems in data centers. The paper provides detail on why each of these characteristics is important, and also explains how and why fiber-optic cabling systems have had to change in order to support evolving data center networking technologies.
The three characteristics Fluke Networks describes are:
- A simplified and task-focused user interface
- Precision fiber channel information
- Effective planning and documentation
On the topic of the interface, the paper explains, "Almost every OTDR on the market today is designed to cover carrier applications. As a result, many have very complicated user interfaces ... While this is suitable for fiber enthusiasts who test telco fiber on a daily basis, it's a different story for enterprise network technicians."
Concerning precision fiber channel info, Fluke Networks says, "With the increasing use of short patch fibers and multi-fiber connections, details on every link are critical ... OTDRs with an attenuation dead zone of more than 3 meters are no longer applicable."
About planning and documentation capabilities, the paper advises, "You should be able to use a single tool to control, monitor, consolidate and document all test results."
The white paper also discusses the roles that preterminated cabling, high-density/high-speed equipment, and virtualization along with its associated network topologies have had on the evolution of fiber technology in data centers.
