How to choose the right MPO Cassette

Low Insertion Loss. The lower the insertion loss, the more MPO cassettes that can be used in the channel—and the greater flexibility you have in your DC topology. Compatibility with Low-DMD Fibers. A cassette using low-DMD fiber is already compatible with systems using low-DMD fiber. This allows the ISI penalty to be reallocated to the […]

Fiber Characterization by Fiber Optic Test Equipment

The following specification is the fiber testers and specification for a cable before delivery. 1. Optical Time-Domain Reflectometer (OTDR) — sends a laser pulse through the fiber and detects the return signal strength as well as the transmitting time. This test shows the overall character of the fiber strand including splice loss, splice numbers, connectors, […]
