Introducing the MultiFiber™ Pro Optical Power Meter and Fiber Test Kits. MultiFiber Pro is the only fiber tester that can test MPO fiber trunks without the use of a fan-out cords, it eliminates the complexity of polarity issues, and it makes cassettes easier to test in the field. Whether it is using 10 Gbps preterminated fiber trunks or planning for next-generation 40/100 Gbps performance, data centers are standardizing on an MPO connector solution. Typical data center fiber installation means time-consuming, manual and imprecise MPO validation. MultiFiber Pro is 90 percent faster than the single fiber testing method because it measures power loss and validates polarity on 12 fibers in a single connector— reducing test time from weeks to days.
