Introduction
Optametra's OM4106B Coherent Lightwave Signal Analyzer Pro™ is a new 1550 nm (C‐ and L‐band) fiber optic test system for visualization and measurement of complex-modulated signals, offering a complete solution to testing both coherent and direct-detected transmission systems. Optametra's hardware includes the OM3105 polarization‐diverse Coherent Modulation Receiver™ (CMR™) enabling simultaneous measurement of modulation formats important to advanced fiber communications, including dual‐polarization (DP) QPSK. Optametra's software performs all calibration and processing functions to enable real‐time burst‐mode constellation diagram display, eye‐diagram display, Poincaré sphere, and bit‐error detection. Working with a real‐time oscilloscope of sufficient bandwidth, bit rates exceeding 160 Gb/s (DP‐QPSK) can be analyzed.

Optametra User Interface (OUI)
The common thread through the Coherent Lightwave Signal Analyzer product line is the OUI which governs the operation and display of data. Color‐grade, persistence, and color‐key options are available to help you visualize the data. In the example below, the horizontal transitions are more rare than the vertical transitions due to the relative timing of the I and Q data sequence (upper middle). The other polarization constellation is shown in color grade with only the symbol points (lower middle). Color grade is also available for the eye‐diagram (bottom right).
