These wide-band multi-mode optical to-electrical converters are designed for measuring optical communications signals. Their broad wavelength range and multimode input optics make these devices ideal for applications including Gigabit Ethernet and Fibrechannel, as well as SONET/SDH up to 2.5 Gb/s. The OE455 is a ProBus module compatible with WavePro and Waverunner oscilloscopes as well as WaveMaster instruments when used with a LPA-BNC adapter.
